- A Bass Players Guide to Matching Bass Amp Heads and Cabinets - johnnycoxmusic.com/
I should start by saying that I'm not an electrician or audio engineer. I'm just a bass player, and this is the first time I've done a Bass Practice Diary video that doesn't feature any bass playing. It's also the first time that I've ever had all of my bass amp heads and speaker cabinets together in the same room.
Combo Amplifier or Amp Head and Cabinet?
I believe that having a separate head and cab has numerous benefits over using a combo amplifier. Combo amps are only practical when they're small. I own a couple of bass combo amplifiers, but I didn't feature them in this video. I use them for rehearsals and small gigs because they're small and they save space. However their use is limited. Once you get up to a medium sized bass rig, combo amplifiers become heavy and impractical.
Having a separate head and cab (or cabs) gives you many more options. Lightweight solid state bass amp heads like the Markbass heads and the Warwick LWA 1000 are small and very light, and easy to transport. And you can match your head up with different sized cabinets or combinations of two cabinets to match the requirements of your gig. Bass amp heads also give you the potential to access much more power (Wattage) than combos.
However, "with great power comes great responsibility", and there are a couple of things that you need to know if you're going to safely unlock the potential of using a bass amp head with speaker cabinets.
Ohms and Watts
Those things are Ohms (Ω) and Watts (W). It's simple stuff, but back when I was trying to work all this stuff out, it always amazed me how hard it was to find this information put together for bass players in a simple to follow guide. I'm not an electrician and I have no qualifications in audio engineering, but this is my simple guide to Ohms and Watts for bass players.
All you need to know about Ohms, is that bass speaker cabinets are rated at either 4 Ohms or 8 Ohms. You need to know whether your cabinet is rated at 4 or 8 Ohms before you use it. If you run two speaker cabinets together (in parallel), then the Ohm rating halves, not doubles. So, two 8 Ohm speakers running in parallel makes a total of 4 Ohms. Virtually all bass amp heads are designed to run at a minimum of 4 Ohms. So you shouldn't run two 4 Ohm speakers together. That would be 2 Ohms, which would be below the minimum level that the amp is designed to run at. You should also never switch your amp head on without a cabinet connected, because that would be zero Ohms.
RMS stands for Root Mean Squared. The RMS power rating (Watts) is two things. It's the amount of continuous power that your amplifier is capable of putting out. And it's also the amount of continuous power that a speaker cabinet is capable of handling. Before you use a speaker, you need to know how many Ohms it's rated at and the RMS power rating. I've heard that some amp companies exaggerate the power handling capabilities of their speakers. They give the maximum Wattage that a speaker can handle, rather than the Root Mean Squared. RMS is the amount of continuous power it can handle. You need to make sure you know the RMS value for the Wattage.
How are Ohms and Watts Connected?
The number of Ohms your speaker is rated for will effect the RMS power that your amp head puts out. When amp manufacturers give the power ratings of their amps, they always give the RMS rating at 4 Ohms. However, if you read the technical specs for any amp head, it should give two RMS ratings. One for 4 Ohms and one for 8 Ohms. For example, the Warwick LWA 1000 is so called because it has the potential to run at 1000W RMS at 4 Ohms. At 8 Ohms it's only 500W RMS.
So, in order to unlock the full power of your amp head, you need to run it either into a 4 Ohm speaker or into two 8 Ohm speakers. However, it's not necessarily a bad thing to connect your amp head to just one 8 Ohm speaker. In fact, that's what I do most often when I take my amps out for rehearsals or gigs. The problem with running very high powered amps at 4 Ohms is finding speaker cabinets that have high enough RMS ratings. To safely match a 1000W bass head at 4 Ohms you'll need a really big rig. Either two 8 Ohm cabinets rated at at least 500W RMS each, or a massive 4 Ohm cabinet, like an 8x10 with a rating of at least 1000W RMS.
Can You Match a Higher Powered Amp with a Lower Powered Speaker?
Surprisingly, yes you can. Some people will tell you, that if you have a bass amp head rated at 800W RMS for 4 Ohms and a 4 Ohm speaker rated at 500W, then the head is too powerful for the cab. It seems logical that an 800W amp is too powerful for a 500W cab. But it's actually fine, as long as you don't push the speaker really hard. If you play through the amp well below full volume, it should be fine. The speaker will let you know if you're pushing it too hard, because it will start to sound bad. - Hudba
I’ve been researching amps and cabinets for months now and this is by far the best explanation of how to pair amps and cabinets. Thank you!
Thanks Andrew. I'm really glad you found this helpful. It took me a while to figure all this stuff out myself. I was hoping that it would be useful for other bass players.
you all prolly dont care but does any of you know of a way to get back into an instagram account..?
I stupidly forgot my login password. I love any help you can give me.
@Leonardo Beau it worked and I finally got access to my account again. Im so happy!
Thank you so much you saved my account!
@Francisco Braylen You are welcome =)
@@leonardobeau149 cheap spam. to everyone reading this shit, its a trap
You’d think it’s obvious but you are 100% correct. No one tells you and it’s not obvious. Thanks for great informative vid.
Brilliant! A true public service to the bass community. Thank you so much!
Thank you! 👍🎶
@@JohnnyCoxMusic excuse me Sir but can you clarify something for me?
@@jbass831 just ask the question
The Mesa bass amps go through this in really good detail in their respective manuals
Crystal clear! Thanks for these explanations, which should be in every amp manual.
Dude, you illuminated a topic that I thought I knew for years but no one ever confirmed. really thank you, this is an incredibly clear explanation
I would like to add that in my opinion, Carvin is very helpful. When I bought a 2x12" bass speaker cabinet online from them some years ago (to add to my existing Carvin R1000 cab and 1x15" setup), it had no documentation, so I called them, and they answered my questions on the phone. As it turned out, I had purchased a 4 ohm cabinet without understanding that I needed an 8 ohm if I wanted to use the 2 cabs together. They helped me sort it all out and now I have a fantastic sounding dual cab setup.
This is exactly what I need! I've been doing research for ages, finally I found it! Thank you so much, mate! You are heaven sent.
Thank you for a much-needed video! So many bass amp/cab makers provide little to no help in their manuals with regard to connecting amps to loudspeaker cabinets!
'Have really struggled to find advice on this subject delivered in simple terms. This was delivered extremely well and, refreshingly, without the sub-agenda of trying to be be cool/hip/happening etc.
Very informative and well presented video.
Ampeg manuals do a great job of explaining this information but it's a lot easier to understand hearing it than reading it in a manual.
Brilliant easy to follow one of the best explanations I have heard thanks Johnny
Seriously, thank you. Talked to so many people over the years who gave poor advice on this topic.
When the amplifier is not connected to the speaker, the resistance is infinite, thus still within the 4 ohm minimum requirement. (In my humble opinion)
Yes, the real reason you STILL should NOT be connecting and disconnecting in a powered on state is the possible sparks on connection that might be damaging to the components or at least cause some really awful noises on the speaker
Very rare that someone can explain this concept this well. It took me a long time to figure out all this by myself, but it's golden information. Thanks Johnny - subscribed just based on this vid alone...
The best video I have watched for a while.
You probably just saved this newb thousands of dollars in future purchases . God bless you , sir .
Well explained topic that helped me understand how to properly match up speaker ohms vs amp watts. I salvaged an old crate cabinet using a new 15”8ohm legend speaker powered by an Acoustic b300hd amp head. The speaker sounds great for the money !!!
Thank you for this video! I've been wanting to build a bass rig and I've looked everywhere for simple explanations on how all this works. This video helps a ton!
Thank you! 👍🎶
This video is so helpful, thank you so much for taking the time to explain all this!
I had to scour message boards to find these explanations years ago. Thanks for putting a video together
This was exceptional
Really good information here and well explained .What surprised me was the lack of proper instructions, especially to somebody new to Group gear amplification that are relying on a step by step guide to safely connect their new equipment up safely.
Great information, I always used Combo amps but now going to head + cabinet, thanks alot!
Thank you so very much for this !! I am looking to buy my first little rig and you answered all my questions
Thanks for the video! Very useful content. 100% true about the manufacturers manuals:)
That's crazy how you're right about the lack of informations in user's guide. The bass player in my former band was playing à TC Electronic combo (can't remember the exact model) which was sold as a 250w amp. We thought it sounded weak for a 250 w amp but we finaly learned that the power rating was for 4 ohms speakers and the speaker that came with it was actually 8 ohms. Wish I saw this video at the time ! Thank you for uploading it !
I have a similar story. I bought a Peavey Max 208 bass combo. The max series are great amps, but their power ratings are misleading because you have to buy an extension cab to get the full output from the amp. Peavey doesn’t like to tell you that.
fantastic information. very well done
Fantastic explanation. Thanks for sharing this.
Thank you! 👍🎶
Thanks, wasn't totally sure about daisy chaining my cabs as the amp has only one speaker output. Now I know its fine.
Thank you so much for this clear explanation.
Wow! Thank you. This is absolutely invaluable information. Without it, one could very easily ruin some very pricey gear. I doubt that amplifier cabinet manufacturer’s warranties cover such operator error damage. As you mentioned, this should automatically be explained within the owners manual… Bless you!
Thank you! 👍🎶
excellent dude!
Wow! Great explanation. Thank you so much
Thank you! 👍🎶
Such a good explanation, saved!
Thank you. Very well explained 👍
Very helpful! Thank you!
Thank you! 👍🎶
Very informative.Thanks.
This is SO helpful. Thank you! Saved my bass-amp bacon.
Excellent!!🙏
Thank you so much!
Awesome videos. Congrats. I love the part where you talk about the setup guide. You're so right. It's not even worth the paper it's written in. No brand explains what's necessary but they tell you to get it out of the box and turn it on ahahahh. Hilarious! Anyway, nice video. Thanks for the help. 👍🏻
Thanks Nuno. Yeah, it took me a while to figure this stuff out for myself, so I hoped it would help other bass players if I put it in a video. 👍🎶
Great video! This helped a lot!
Great info!
Thank you!
I keep hearing that you have to make sure your speaker cabinet has enough power handling capability. Maybe things have changed, but I learned an important lesson back in the late 70's and early 80's with my stereos. As a teenager, I had a 45W Kenwood stereo receiver going to 100W Kenwood speakers. I must have blown out a tweeter on those speakers 3 or 4 times over a few years. I learned that since the amp wasn't a very high wattage amp, it was clipping the signal, and that's notorious for blowing out tweeters. In the 80's, I purchased a 250W Soundcraftsmen amplifier. That beast never blew out speakers...EVER! We even tried to blow out an old pair of Radio Shack speakers (I think they were rated 100W), and we couldn't. The signal from that amp was so clean and it never clipped. Maybe this principal is more applicable to tweeters, but since then I've always chosen to error on having TOO MUCH amplifier power over too little.
Thanks Greg, this is useful info. 👍🎶
Thank you!
From memory, my SWR amp manual had a quite a good explanation on single speaker vs parallel speaker impedance and amplifier output. I think there was a couple of pages on it. Including what gauge cable to use.
Analogy of ohms to a head:
A bucket full of water w holes drilled in it.
1 1/8 inch hole drains so much water. Imagine that 8Ω.
2 1/8 holes give twice the paths for water to pour out, less resistance, twice the watts at 4Ω
1 1/4 inch hole is less resistance than 1 1/8 inch hole so flows twice the juice. Imagine 4Ω.
2 1/4 inch holes are half the resistance of 1 1/4 inch hole, half the resistance, twice the flow.
Imagine 2Ω. This amount of juice burns out your transistors.
The analogy is imperfect because circles have a lot more area for twice the diameter.
Awesome video!!👍👍
New GK amps you can run without a cabinet plugged in
Tc Electronics explains every possible thing that you need to know with ohms and power ratings for bass heads.
Excellent video man, thank you. My new head's fans went insane, I plugged into a load with a bad speaker cable and I think maybe it was cutting out connection to the load. I made sure to turn it off when that happened. I also played not plugged into a load, but with the headphones connected. My head is OK but it would have been nice to know not to turn it on unless it was plugged into a load. I also had a knob turned way up that could have damaged the speakers and didn't know that either. I'm pretty sure my head and cab are OK but damn what a couple of close calls, especially when I was playing loud.
It's a Peavey MiniMega 1000 watt head connected to a BAG END Q10BX-D. I'm still hoping I didn't damage anything WTAF.
Wow this video was great! thank you so much
In practise it’s fine to run an over or under amped combination
, you just need to be aware of the potential issues. For rehearsals I generally use my 700w amp with a 2x10 that’s rated 150w. As long as I don’t drive the cab too hard it’s fine.
I don't usually comment on YT, but this video is just brilliant!
Thank you very much! 👍🎶
A very good and informative presentation in a subject not well covered. I would question one point however that was stated about not turning on the amplifier without a speaker being plugged in. An Ohm is a measurement of electrical resistance. With no speaker plugged in the electrical resistance would be infinite not 0, therefore it would do no damage to the amplifier. "0" resistance would be considered an electrical short circuit. Infinite resistance is , well infinite resistance.
Again a great video.
Thanks
Nice Jonas Hellborg stack there in the right, btw 🤘
Thx for this video, i learn so much about this world of connecting bass amp with cabs ! I wish you all the best ! By the way, my Hartke LX8500' users manual does explain properly like you the impedance !
Thank you! 👍🎶
Thankyou, thankyou, just bought a Markbass AG 1000 and wondered how to connect to two cabs.
This is great information! Thank you.. But I'm curious what happens if the bass head has 2 speaker outputs and you connect both to the back of the same cabinet which has 2 inputs?
When you connect no speaker on a Digital amp you do not have 0Ω but you have ∞Ω. This does not destroy any digital amp because no current is flowing. On a Tube amp - in opposite- the lack of load will bring your Tubes into a bad area of your amplification curve so the result could be defective tubes (depending on circuit). Also the Ω on Speakers and Amps is impedance not resistance. it is not static but the 8 or 4Ω are averaged out resistance values over direct current measures. As every Speaker has different impedance response even when connecting the "right" impedance it can lead to strange effects as the speakers influence each others response. All over Digital amps are easy with anything and I have seen no Digital amp blowing up below 4 ohms just yet. Might sound a bit bad but hey.. it´s digital ;) . I still appreciate your efforts telling folks a little about this. Yes manuals are ridiculous everywhere
Thanks for the clear explanation.
I got two 8 ohm ampeg cabs and an ampeg head (svt 4 pro) that has both, 2 separate outputs and a mono output.
Is there an advantage to connect in daisy chain (As i do now) over 2 separate outputs ?
Note : i use this seup only in my music roon, no live, too heavy...😊....for live i use a more handy combo.
Thanks
Hi, thanks for upload this video. I bought a line 6 lowdown HD750 amplifier (750 w) and i want to buy two cabinets of 8 ohms. Wich brand do you recomend me? Hartke, ampeg or gallien Krueger? I was thinking about buying 4x10" cabinet 500w RMS, and 1x15" 400w RMS. It doesn't matter that 1 cabinet has more watts? Thanks in advance
Same concept applies with guitar amps push higher wattage amp through a lower wattage speaker and you can blow it with ease for example if I take my origin 50 and drive a orange 1x8 mini cab I can end up blowing the cab because the origin 50 is a 50w head, always match your amps wattage to your cab you can get away with an lower wattage amp just remember that you’re not gonna be as loud as higher wattage amp though it’ll still get loud, running my Friedman be mini 30w solid state mini amp head through a Marshall 4x12 240w cab and it gets pretty loud.
Thanks, I just bought a Warwick head, and indeed no mention of how to correctly pair it with a speaker. In step one, they do mention the need to unpack the amp, albeit for this instruction they write in German language, while the other 4 steps are English. If my German was even worse I would have totally missed that first step...
Hi Johnny. Great video. I have a question about tube heads.
What would happen if I ran a Fender Super Bassman 300 through a Markbass 104HF that is rated 800 watts at 4 ohms? Would there not be enough power from the head to the speaker (if I ran the head at 4 ohms)? Or would the tubes be too loud for the speaker to handle? Thanks in advance.
Hey man I got a question.... so I have a mark bass amp combo,“ CMD 102P” the impedance is 8ohms and I just got a mark bass cabinet, so I didn’t know which one to get so I got the 4ohms.... is it fine ? Or should I get the 8ohms?
The cabinet I have is the
“Markbass Traveler 102P Rear-Ported Compact 2x10 Bass Speaker Cabinet 4 Ohm”
And the amp combo is the
“Markbass CMD 102P 300/500W 2x10 Tilt-Back Bass Combo Amp”
Hi Jonny, great vid, thanks. My question is about turning on an amp without connecting to a cab. A lot of heads have a headphone out socket for quiet practice. Surely if the head has this feature I wouldn’t need to connect to a cab? Unless of course connecting headphones mutes the output to the cabs? Any advice appreciated. Thanks.
I appreciate the little labeling you did during this video to differentiate the steps you are explaining. So, I got a Ampeg 6x10 cab that has a power of 600W @4 Ohms. But I want this Ampeg V-4B Tube bass head that only has a power of 100W and it supports 2, 4, and 8 ohms. What are the cons (and/or pros) of having having an amp head with a power that is significantly lower than what my cab can put out?
Hi Arthur, I can't give you a technical explanation, but I've been told that it's not a good idea to use a head with a low RMS power rating into a cab with a much higher RMS. I believe it's not good for the amp.
How are you doing the calculations to find the wattage rating needed from the speakers when you change the ohm value?
Hey boss! Love the video! My question is this. If the cab I bought is rated for 800 watts rms at 8 ohms (acoustic neo 4x10), could I use an amp that was rated at 500 watts rms/8 ohms? I've been trying to find an amp that will pair well for modern rock and some pop. Thanks!
Hi, thank you. You can use it. Some people say that if the head is underpowered for the cab, then the amp has to work too hard. So, it probably isn't a perfect pairing. But, I've paired amps and cabs like that before and I've never found it to be a problem.
Important question. If I have a bass head that is rated 400 watts at 2ohms, but only 175 watts at 8ohms, and I’m running it into an 8ohm cab, is it safe to use a cab that’s only rated for, let’s say 200 watts RMS? In other words, does more resistance make it safer to use a cab less power handling?
If I have a portaflex PF500 amp head at 4 ohms, I can connect it to an Ampeg PF-410HLF 800 Watt Bass Amp Cabinet 8 ohms, how much power would the amp give me with the cabinet? I'm sorry for English, I use a translator
Hi. I believe that amp is 300W at 8 ohms. 👍🎶
@@JohnnyCoxMusic muchas gracias amigo, saludos desde Lima Peru
good video!
If I need more power for a gig I’m entertaining the idea of adding a fender rumble 115 v3 extension cab (600 watt 300 rms 8hm) to my ampeg ba 210 v2 ( 283 watt @ 4ohm, 450 @ 8) via the extension out jack.
Other than offending other bass players do you think this is an advisable pairing spec wise?
My thought process is to add a 15 for more low end thump where I already have 2 10’s handling the punchy sound.
I’d love to get some feed back!
Thanks
Very helpful! I have one question though. I’m building my own 4x12 bass cabinet. The Eminence speakers I’m looking at are individually advertised as 500watts and 4ohms. Since there will be 4 of those in the cabinet...would it work properly with my 900 watt/4 ohm head? my amp head also has a button that switches to 2 ohm.
I do not claim to be an expert, but you control the impedance (ohms) of the cabinet in the way that you wire the internal multiple drivers. If you wire, for instance, two 4 ohm speakers in series, then add 4 + 4 to get 8. The formula for wiring in parallel (please look it up) is not quite as simple as it seems, but two loads of 8 ohms in parallel gives 4 ohms. You'll have to decide what total ohms of the cab is desired and then wire the four speakers in a combination of series and parallel circuits to obtain the desired ohmage.
Appreciate the info
I use Warwick cabs and a 86' Hiwatt Bass 100
Looking at a Warwick Gnome 2x8 200w for potability
Thoughts?
Very informative thanks! Now, would it be ok to use a standard (guitar) right angle connector adapter going into the cab? Will it destroy the cab? Or is there a special speaker cable right angle connector?
Hi, hopefully you found your answer but in case not - please do not use guitar leads as speaker cable. Especially for bass amps. Instrument cable is designed for the incredibly low signal that comes from guitar pickups and is simply not designed for connecting amps to speakers. While it will "work" - you'll get sound with your tone and maybe even for a while - it's a fire hazard.
Please, if you haven't done so already, go into your local guitar store and ask for speaker cable to connect your amp to your cabinet. There are 2 kinds; a standard looking connector that looks like instrument cable, and what's known as Speakon connector. Most amps can use speakon connectors but not all speaker cabinets do so check your rig first. :)
I think I have the answer from. This but I'm just not sure.
I have a marshall dbs 7400 amp head and a marshall dbs 7415 cab. I read the amp is capable of pushing its peak 2000 watts at 2 ohms. So am I able to get another 7410 or 7412 and run them both with the one head and get more power ?
Really cool video ! I’m considering buying an Aguilar Tone Hammer 500 (500w on 4ohms) and pair it with a SL 210 (400w on 4omhs). My question is : would you say that it is not too risky and that I’ll just have to make sure that I’ll never push the master volume over 75% ?
Hi, thank you! Yes, If the the Cab is rated at 4 Ohms and 400w RMS then I would say it's well matched for a 500w head. The RMS rating on the cab tells you what the cab can continuously handle. It should be capable of handling short bursts of more than 400w. So, unless you're planning to run the amp head at full volume a lot (I'm sure you're not) then you won't have any problems. Also, you'll hear if you're pushing the cab too hard and you can turn it down if necessary.
@@johnnycoxguitarbassschool3957 thank you very much ! It’s pretty clear now, will go for this set up 🙏
If you would have an amp of like 300 watts at 4 ohms and you put it into a cab of 600 watts at 8 ohms, how does that affect the sounds? Would it be a lot lot quieter? Is there a change in tone? What would happen?
I have an Ampeg SVT 4 PRO I was wondering can I mono bridge the head into one cabinet and then run out of the that cab to another and be ok?? And how is the wattage distributed? The amp in mono bridge is 1200 watts
I have the orange terror bass head and a 4ohm 500watt cab. I would need another 4ohm 500watt cab to match that. The head is 4ohms at 500 Watts so can I use 2 500wat cabs?
If they are NOT tube amps yes it’s still good to plug everything in first but toy won’t damage a solid state amp without speakers only tube amps require speaker load
Very interesting, thanks a lot!
What happens if I have a 1000 Watt head, and I plug it directly into the PA, and no speaker?
quick question, I have a Hartke 4x10 XL. The inputs are 1/4 and Darkglass and Aguilar amp head has XLR output. Can I connect these amps to my cabinet? do I have to use a XLR - 1/4 cable? thanks!!!
Can you explain peak watts? I just want to be sure I'm getting it. I don't want to ruin my head or speakers and I want to get the best sound from them that I can. I've really only ever used combos and the 1 setup I had was set up by my dad (who doesn't know any of this apparently). I have a 600watt head. It says the minimum is 4ohms and it has 2 speaker Jack's marked 8ohms. So it's telling me to plug in 1 8ohm speaker in each jack, and it'll give me 4ohms and the full 600? Am I getting that correctly? Sorry for the silly questions, but your video seems to be the best on this subject so I trust what your telling us. Thanks again.
God bless
Thanks man! i've got 1 question. Can you run a head wihout a cabinet and only use the headphones?
question. I'm very new to all this. if i plug a 500w@4ohm / 300w@8ohm bass amp head into two 800w 4 ohm, 8 ohm cabinets, how much wattage in total would i be able to output? and would such a setup make sense?
Hi mister.
Thanks for the video, very useful information and really well explained.
My question is about the Warwick cabinets you have there. How good are they?
I have the chance to buy a WCA210 cabinet, very similar to 2x8.
I assume they are good enough for delivering quality sound produced by your Markbass amp, but I would like to hear your opinion.
Thanks in advance.
I have an Aguilar tone hammer 500 head by the way.
Thank you! I like the Warwick cabinets. I've used them quite a bit with my Markbass Little Mark III head. I think they give quite an honest representation of the sound of the amp. They don't colour the sound too much. The 2x8 doesn't give a huge amount of low end, but you wouldn't expect it to. 👍🎶
@@JohnnyCoxMusic Thank you, I really appreciate your opinion. There is very few information about this cabinets, and is really helpful to have a honest commentary about them.
please explain Johny , how come compos have an 8 ohm speaker in them ? do they run at half their nominated power ? thank you
I played an open air gig the other day nothing major . And my ampeg bass rig was good . But I had a thought I’ve got another 1000 watt amp at home , so my question is could I run both amps together to get serious power / volume .
I have 2 500watt speakers ( 4x10s ) x 2
If I did run the Amps together would I run the risk of just blowing the speakers up .. ???
Johnny, you have a strong resemblance to the Drapers in the USA,nice family any connection ?...love your info keep up the great work
Thanks Willie. I don't know the Drapers.
Let make something else clear? That possible 1000 watts is its peak unless it’s stated “1000 watts continuous.” Just like the speaker,600 watts programmed or musical? Like let’s say a CD being played through it or your raw bass guitar signal? You’ll damage a speaker just as quick by under powering it as you will over powering it. Under powering a speaker makes it sit still when the amp cannot give any more. That speaker at which point is not moving “In/Out” but rather sitting in one position of movement therefore frying the voice coil. Good video and nice amps by the way.
thank you so much for your explanation, Greetings from Peru
Hello! Thank you!
I have the darkglass 900(900 watts at 4ohm) and it has two speaker outputs at 4ohm. Is each speaker connected receiving 900 watts or is it 900 watts in total?
Hi. It would be 900W total.
I think its tube amps (with power tubes) that need to have a speaker load on them, cheers.
Great content .... but what about adding cabinets in series ? I wonder why someone would do that since it would make 2 8 omh cabinets 16 ohms. Not sure of the math, but would that not run a 800 w amp at about 300 w ? What benefit would that provide?
help on pairing a 200 watt green matamp to a 4x10 1x15 cabinet , 4 or 8 ohms?
What's the appropriate cabinet for pairing peavey minimega bass head? 🤔🤔
Really good was that, you know you're stuff and willing to share it. Do you know anything or have any ideas about slaving bass amps or linking two amps together. Cheers
Just purchased a Mesa D350 head with 2 1x12 8 ohm subway cabs. With this combo am I safe and will i achieve the max 350 while running all together. Thx for all. Bob
