Be careful mate, someone's pretending to be you..
Bro I think you got hacked. I got a message from "you" saying to text you with a phone number.
@@drgenerico83 they are scammers ignore them. It's not me, they are using my profile photo
A bank of many smaller capacitors tend to be cheaper than a single 10,000µF capacitor. Also, a big cap tends to take up a lot of vertical space, while a bank of smaller caps will take up a lot of horizontal space. So the dimensions of the box, and the space available on the circuit board plays a role here too. Plus, smaller capacitors will charge and discharge faster than a single large one. This improves transient response time - basically, the speed in which current can flow in and out the capacitor to the rest of the unit. The faster this current can flow, the less the signal is distorted when there is a sudden, high current demand, and the sooner the caps can recover after being depleted (or nearly so). This results high frequencies sounding better at high volumes, and bass notes retaining their "punch" at high volumes.
But every capacitor has leakage. This is a tiny amount of current lost within the capacitor. No capacitor is perfect. And when we add a bunch together, we add up the leakage. So we use special capacitors with low leakage - but slightly more expensive. And using capacitors rated at double the voltage for their intended use also lowers leakage - again, more expensive. Thus, a 35v application would use a 70v capacitor to minimize leakage. Cheap engineers and/or manufacturers will use caps at or near their rated voltage to save money. Too much leakage, can reduce the voltage available to the unit, reduce efficiency, and reduce the life span of the caps themselves. Also, each cap has a tiny chance of failure at any given time. So a large bank of many small caps increase that chance of failure by the number of caps.
Sometimes you will find a small cap in parallel with a large cap. This small cap is called a bypass cap. It's there to handle those fast transients (high notes at high volume) while the big cap handles the bulk of the current demand. it's not as effective as a bunch of small caps, but the failure rate is far less, and it takes up less real estate on the circuit board. You may notice that some boards have all kinds of free real estate, while others are crammed with electronic components.
This absolute explains why my JL hd1200.1 amp has so much more punch than my previous infinity k1000. Both used the same input signal and keeping same settings it sounded so much more punchy.
When you put bunch of them in parallel it also reduces the parasitic resistance aka ESR...
This kinda knowledge is priceless and was explained very well, even a dumbfuck like me could fillow that 😂 cheers bro 👌
High voltage caps have a much higher ESR than lower voltage ones so you will more of them. Using caps rated at higher temperature and voltage drastically improves their lifetime (doubles for each 10deg below their rating)
Wish there was distortion, intermodulation, and also more circuit layout discussion like we get on ASR forums. Parallel caps have lower ESR than usually can be achieved in a single larger can. I think Panasonic doesn’t even make large value snap-in capacitors anymore.
Have rocked jl audio for years. Still have a 1000/1 anp and a w7-8 kicking around. Expensive but very quality stuff!
I've bought 3-4 XD amps used. They all continue to work great years later. Highly recommend second hand if you can test them, avoids the high price.
The xd line is fairly easy to repair
@@jakep8484 good to know! One used purchase has something rattling around inside but still performs fine.. so far.
@@Geoff240ti i would check that out, could short something eventually. Xds and slash are my favorite jl amps.
@Jake P good advice, I'll pull it from that vehicle and have a look. Haven't tried a slash amp yet, any other favorites from other brands?
@@Geoff240ti well full disclosure I used to work for JL so have only repaired JL amps but the class ab rockford amps and audio control amps look interesting as well. As for subs though I love my JL 10W7 and that has nothing to do with my history, its just a really smooth, deep and musical sub 👍
Love your videos. This is one where I wish you had done a sub test. It's always good to see.
I still use my JL Audio 500/1 you helped me decide to buy years ago.
Thank you Big D!
Same
I have been using my XD400/4v1 and two XD600/1v1 amps for 15 years now. They have never had an issue and always sounded great. It's great when you get what you pay for, quality and reliability.
Love the videos you produce Big D. My favorite by far!
Thank you for watching and commenting!
another one i've
been waiting for thank you BIG D
Use to have one of these amps on 2 13W3 amp is a beast and did wonderful on stock electrical.

Oddly enough back in the 90s when I was big into this stuff, you were expecting to pay $1 per watt, for real world clean power. At least in Canadian dollars anyway, which at the time was about 35% less than USD.
I do like that JL hasn't sold out it's brand and turned it into garbage.
Time will tell if this statement remains to be true.
I'm on 20 years with my 500/1 and 5 cars still rocking after 2 car accidents with the sub box hitting it. Tis but a scratch. Battle scars!
I use a XD600/1 v2 and I get 990w using a SMD DD-1+ 40hz test tone. I currently have it set for 850w to match my 2 12Tw3s. Sounds fantastic!!!
Thanks D for another cool video. 😎
The Gomer Pyle cut is new and funny. Thanks.
The RCA not Tiffany and no bass knob ouch for the price no low ohm load for how much 🤯🎶🎵🛠️👌👍✌️
Good looking PCB. From my understanding, an array of smaller caps will have for plate and terminal surface area than fewer large caps. This can ensure faster current delivery as well as power and heat dissipation.
Yes, due to the lower series resistance and inductance. Less power loss and heat dissipation = longer life.
Lower ESR
And you can put that pcb into a slim case. Wouldnt be possible with a huge, round single cap.
@@napnapnop So prior, engineers knew nothing of ESR and current delivery? Today, still few home amps use a small cap array.
Many smaller caps will have a lower ESR resulting in faster and higher current capabilities. Also, you can distribute the current across more conductor with many smaller caps to distribute (heat) current load across more conductor, resulting in better cooling.
Thanks for the info, greatly appreciated. These are a pricey item & they are not giving any breaks. Quoted 18 bills for a vx800/8i, and not a dollar less, even after trying to haggle for an hour or so. I bounced. It appeared to be an impressive amp, that sounded great.
The smaller capacitors that are tall rather that wide, this has a better geometry to reduce inductance in the capacitor, ESL (effective series inductance) . As a result they can transfer current better at high frequencies. Since the power supply switches at tens of kilo hertz, this is beneficial since it can deliver power with minimal impedance. The effective ESR (effective series resistance), this has to be low to minimize heat generated in the capacitor, this is stated as you can see on the capacitor "Low ESR", this not always the case.
I love it when you do JL amps! It would be interesting to see how the lesser of the mono blocks do in comparison.
Thanks. Good result.
Watching from Jamaica 🇯🇲. Like when u see this
Have a wonderful day friend in Jamaica! 🍻❤️🌎
Don't tell me what to do... Lol
"Fire in the hole" is an excellent catchphrase, and you should be dropping that line before the start of your Dyno test every video.
Made me laugh so hard!
The dope ass amp. Packs a lot of powers for the features and it's going to be clean as be as you would expect from audio control😊
😅😅😅😅😅
Where was the audio control amp?
@@ah4800it was a way back 😊
JL has always designed and made clean products.
I ran JL subs and PPI pro mos for years , these remind me of old PPI SUPER high damping got to get the 1000 this year 😁
I love JL Audio
I had the small 250 watt mono JL amp on a single dual voice coil 8” and it was awesome!! GREAT headroom, never got hot, and never heard the sub distorting due to the power. They make some great amps, but are DEFINITELY overpriced.
Using many smaller capacitors in parallel instead of few big ones lowers the ESR (equivalent series resistance) of the capacitor circuit helping with dynamic current delivery.
I've had the xd600/6 pushing my front stage Audio Frog GBs for several years. Never an issue.
Great video!! Can you test the Audiopipe APMOX Amps?? They’re tiny - I can’t believe the power handling 😳
I have the jx1000/1 and it still works great
Hey. I enjoy enjoy your videos and you have become my go to when looking for power on a specific amp.
On that note. Is there any chance u could do a test on the DD audio M4?
Not m4a or b. But just the last generation m4? I’ve looked all over and haven’t found that on a dyno.
I went to that from the sundown salt 4 and it seems significantly more powerful. I ran them both at .5 ohm.
Thank you.
1000 at 2 ohm is not bad. Would be a decent single 12 inch setup. Thinking back I always saw these amps used in installs that for example, a friend of mine who does not work on cars, went to a shop and just had a single 10 inch system installed with the custom made boxes they sold designed for each model of car to fit in spare tire spaces or where the jack would normally be. It would always be an alpine head unit, a CD changer, a JL audio amplifier, those custom boxes and a JL audio sub either 10 or 12 inch class. I remember the one in my buddies firebird was a 10 inch JL in a sealed custom box that came out to be just under one cu ft stuffed with poly fill.
Good high quality ✅ JL audio fantastic for the money 💸 fantastic factory 🏭 control.
Love how you show the wire setup on a subwoofer, ohm load
I'm dying at the amp that doesn't catch fire statement after watching Parker the basehead video on his new amp catching fire this morning.
He used some sketchy brand I never heard of. Probably has sketchy protection circuit.
He used a sketchy designed subwoofer. Basically a novelty subwoofer, that he previously damaged and cob-job repaired. The sub had a dead short, from it rubbing the top plate under heavy load the first time he "tested" it and the spider lifted. Sub died, and killed the amp. It happens, and could happen to any amp..full or half bridge. Parker isn't the best, at doing actual tests and or reviews most of the time. But he's entertaining.
@NoB.S Audio agreed. He is backyard mhead style. Comedy not review.
@@numlockkilla 💯 agree
@@Bassotronics that amp that caught on fire is a common amp sold on Alibaba. Just rebadged. Now, on that same note, the Teampie amplifiers are also sold on Alibaba unbadged with the option of branding it with your own brand if you purchase like 5,000 units. EMF audio , along with many others all use the same amp with their own branding on them.
Salute! Solid reliable quality amp. You get what you pay for. Buy what you can afford Bassheads.
JL is the best😂😂😂😂
The smaller caps have a few pros. Reliability, life expectation is higher. Better temp stability. Reduce fire hazard IF one fails. Lower internal inductance for a faster response.
Cons
Cost more the higher price of a single cap is generally less then the combined cost of 3 or 4 smaller caps plus most caps are installed and soldered by hand so more costs with more assembly.
Board trace layout and space. When placing multiple round cans you take up dead space between them. Batch control Generally you want all the caps together to be from the same batch or match esr and inductance so they share the load evenly.
Love the content and JL! I have had JL Amps, Subs and speakers. It would be cool to see a Slash 1200 on the dyno!
Do you still daily a 10w6? This amp would push it quite nicely!
I actually like that you show an 8 ohm load.
20 years ago I would have bought two of those amps, a couple of W7 subs, mids and a matching 300/4. All after spending a couple of hours at my favorite stereo shop killing time with friends and installers. Now I just putz around with my untouched factory stereo doing boring adult stuff.
Big "D" always rocks and well worth it! The amps, well, that's why we have you, to help us out and everyone has their preferences! Just crank that puppy up and let's rock! 🔈🔉🔊🍻❤️🌎
Dayum son, you gave me a heart seconds after I posted! And this is why we love ya! Just make sure you keep being you and we appreciate you! ❤
The multiple small value capacitors equal lower impedance, which equals releases the energy quicker with less loss. This was pioneered by Peter Stein of ME
Sound in Australia.
I believe many amps who aim for quality still have amps that are only 2 ohm or even 4 ohm stable in bridged mode. I do believe the higher impedance is better for SQ in my opinion.
All is starting to make sense why you sent a heads up on JL's discounts recently. 🤔 😏 I did love my 2000s JL500.1.
Would love to see a bench test if the diamond audio des1000.1 have 4 of them on my home set up and they are great!! Also beyond very efficient!
I have a JL Audio JX1000 class D amp. I've been waiting for a dyno test on here, nothing so far. I would gladly send you mine to test.
Had 2 of these amps die at the same time in a build. Power supplies both went down virtually simultaneously. Very surprised. No apparent reason why. Was told this is not uncommon under prolonged low voltage conditions- which were seemingly not the issue on this particular build. Not sure if that’s accurate or not. Owner repaired at $400/each and have been fine since. A couple lemons maybe? Nothing against JL. They’re okay. Basically the Apple of the mobile/marine market though. Price to performance ratio is sub par at best.
You can never expect even the best amps to survive if someone with no knowledge of decent electrics keeps beating on them…All amps will die eventually under those conditions..
@@justkiddin1980 That’s presumptive, but again, since repair there have been no issues with either amp. Going on nearly 2 years since repairs without change in the electrical system (which consisted of HO alt and Northstar AGMs) or non-abusive listening habits.
"Basically the Apple of the mobile/marine market though."
Which is why I buy Audiopipe amplifiers for my vehicles. They make their rated power and are not overpriced.
possibly a loose connection
ok big D since this isnt a mi9ckey mouse operation which would you buy D4S or JL A?
One of the best brands ever. Quality is always better then quantity! Thank you Big D!!!
One thing JL Audio always provides is super clean and deep sounding bass, especially when you pair their amplifiers with their subwoofers. I always enjoyed the tonality and accuracy of JL equipment. The numbers on the amp dyno don't really address that (SQ) aspect, but it's very important, and its why they are justified in asking a higher price, imho.
I had that Amp. Played it in the Arizona summer 110+ degrees windows down no ac. on 3 JL audio w6v3s. Max volume. No issues, never overheated once in 4 years. Sold it for a more powerful amp
Great comment sir. That’s fantastic to hear.
The gentlemen who engineered this amplifier live and work in Phoenix. They are acutely aware of real world temps in cars, in the summer, in Phoenix. (I know this because I work with them)
Good video Big D
And another one... (another what one may ask lol) Well another consistently great video from Big D of course!! Thanks D.
JL, you can be reassured she'll keep the sounds bumpin for many many many years without issues.
JL audio is quality.
I have 2 w7’s with this amp one on each sub….. it rocks
A caps tolerance is typically plus or minus 5%. The bigger your cap the bigger your tolerances need to be. By using smaller caps you can tighten your electrical tolerances.
Armchair EE nerd here. Electrically, the equivalent series resistance ("ESR") of a capacitor is a big reason why a choice would be made between giant bulk capacitors and an array of smaller ones (as JL has). Just like with the woofers when paralleled, more small capacitors will have a lower ESR, allowing the capacitor array to handle a much bigger peak power draw, as one would see with a thundering subwoofer in a typical music application. There are other considerations as well:
-Heat dissipation (more capacitors = more surface area for cooling)
-Space usage
-Cost of bulk capacitor vs. capacitor array
I don't think any of those are a major concern for JL Audio in this application, because:
-The enclosed housing and cluster of capacitors wouldn't do much for dissipating heat from the capacitors
-They clearly have plenty of space
-JL seems to consistently prioritize quality over cost. (I do too.)
Thanks for covering, Big D. 👍
Hey WA Lab… I wanted to see if you can either answer or both answer and show amps that have best efficiency. By efficiency, I mean amps that do not tax an car’s electrical system too much, and would/could possibly perform well without huge power output upgrades. Many of the amps you show with decent power take so much amperage to run, that an 100-150amp alternator would barely put out to keep up with most of those 1k amps. And since most newer car’s electrical systems are really sensitive to voltage spikes and drops, that would be a cool series to help people that want to bump & retain an unmolested factory electrics- or mildly upgraded ones that just need a cap or additional battery. Cheers
Thoughts on a used JL 1000/1 like this or the JP23? I have 2 X JL 12W3s and had a JP8. I felt I was maxing the amp and the speakers wanted more than 400 watts each that the JP8 was providing. Ive had XTANT in the past, so Im familiar with quality and damping of the amp. I just want to make sure Im getting loads of easy clean power to the subs.
thats cool never seen a amp that rapidly went in and out of protect
My buddy had the old version 1000.d that he cranked all day long. That thing would get warm and that's it. It powered 2 kicker comp r 12's. Not the most powerful, but you probably won't blow it
Dunno about this xd line but the HD 1200 is the best I’ve heard. Put up against a taramps 5k and even at same volume or louder the JL is just more detailed. I really tried to make the taramps good enough but it just can reproduce the detail like JL can
Thank you for the vids
Is there any chance you could Test the JL 10w3v3.4 sub?,thank you
Using more small caps help distribute the power more efficiently
Love jl 4 life
I really don't mind not seeing it blow away the rated power. For ppl not competing in an amp class it makes the most sense to just know what you're getting.
These days without a Big D video you might not know if an amp does half or double it's rated power
True, as long as the amp does its rated power, I'm happy with that.
Gone are the days of the J.C. Whitney catalog where you were pretty much 100% guaranteed what you were getting was no more than 10% the advertised power - or less. So many of us were so uninformed back before the internet.
@@jdlech Pyramid for the WIN!!!
@@jdlech At least in Europe there are still some brands that claim 1000+W for something like a 2x50W puny thing.
In the worst case (Auna) even less power and even more bloated numbers, like 6000 or even 10 000W (6 channels and a bit over 400 W total at 13,5 V and 1 % distortion) and one example (Auna AMP CH 02) that is marketed 1400 W max and has 34 W of total power, or the AB-650, 4800 W max, actual power 96 watts total to SIX channels! Technically they can be compared to something like 80's boomboxes as the amp chip(s) run straight from the 12 volts.
@@jdlech my first sub was a 12 inch subwoofer from JC Whitney and a two channel Boss amp in 1997 or so
I have Jl products so I really appreciate these videos. Could we get a dyno of the RD1500/1
Thanks for the suggestion
Still watching, but I expect this JL to be quality!
Capacitors have internal resistance.. more caps less resistance.. so the power supply can handle short high current power draw..
Hey, Big D. Power acoustic has a powered 8" sub at Walmart. Comes with a bass remote. Would like to see a review of this.
JL Audio has always been a company that delivers well-thought-out, well-designed and reliable products. And these things shouldn't be cheap. The question is whether it can compete on price with European or Japanese amplifiers. If we talk about real SQ, I will always choose a European or Japanese amplifier for not powerful (60-80 watts per channel) 4-channel amplifier for midranges and tweeters.
As for subwoofers or subwoofer monoblocks, JL Audio has succeeded in this.
Thank you for your test and review.
Sorry JL Audio is low budget subwoofer & Amplifier,too expensive if you want deep bass they are not the way to go
@@poohwecampbell7799 I'm actually talking about sound quality and not about SPL. I'm pissed off by cars that can hear bass from half a mile away. Well, to each his own. In terms of sound quality, JL Audio does a great, right bass.
Hey buddy have ever tested a 'power accustic' over drive series 3500 if so can you let me now how it tested. If not u think u can test one would really appreciate it. Thank u love ur show
I would like to see you test a sundown audio SAZ 2000
Though i myself do not use any JL audio stuff i can say sometimes the high end priced stuff does last. I have a buddy with a rockford t1500.1 that has been pounding away for sooo many years now without a care in the world.
Could you do a jp8 strapped/linked dyno run. I just got a second one. And I am just curious. 😊 thanks D
Many caps in parallel is lower internal resistance. No point having large cap if it can't discharge fast
Gotta pay for that RnD to get that JL quality :)
The fixed frequency subsonic is the worst thing about it, in my opinion. It really would make it so that you'd have to build a ported enclosure with that in mind. On an amp of that cost, it should certainly be variable.
That is my okay gripe with their amps. I bought the HD1200/1 amp. I love it but there's no adjustment for the subsonic filter as its fixed to 30hz.
7:15 The idea is supposed to lower the Equivalent series resistance of the capacitance. The theory is the smaller caps should discharge much faster.
What a lovely Amp! 😊 Guess i wouldn´t buy it, but it sure is a great piece of engineering.
BTW: 1000V seems quite a lot for the rail-caps. They might be rather 100V.
Did I say 1000V? Geesh 🤦♂️
I love it
Multiple capacitors can charge up way faster than a single capacitor. This allows for much faster power response.
Big D still waiting for the hifonics colossus vi test you promised about 10.5 light years ago
I'm still waiting on that cha ching you promised! Goteem!
I would assume the smaller caps charge and discharge more efficiently. Just a guess.
In general 1 per watt is the bar and has been for 20+ years in my book. That's just a very general rule of thumb that's rare to go wrong. That obviously changes the more you understand audio. Love the videos big d! Stay cool
The bar is 10 cents in 2023. You can’t tell me this amp is better than a CT sounds or D4S.
@alconyers2003 no I'm definitely not saying that. That's old technology, depending on how old you are that was the height of technology 20 years ago and was the same price, we didn't have those options. So what I'm saying is that this is something that someone buys that has more money than brains nowadays. Now there's so many options it makes me jealous, I can barely keep up. Now big box brands aren't even on my radar.
look at the Taramps... 26k RMS power at $3,500.00
not to mention 1/4 of the size of the old stuff... its crazy
1$ per watt was always my rule of thumb and expected over the past 30 years or so. But I also remember getting Orions the size of surf boards back then.
Amp tech has definitely come a long way, but I do still wonder if the audio quality is the same now as it was back then, or if all people care about nowadays is just pushing the subs, and audio quality comes second.

I’m sure I got this wrong and I’m going to get a bunch of flack for this. Did the engineer who designed the PPI art series amplifiers go from Precision Power to Xtant and then finally to JL? If so then the JL amplifiers at least the ones from around the late 2000 would be the final descendants of the art series lineage?
Please do the test of the crossfire CFA 1000D
Great 👍 video.
Does what they say it does, that carries a lot of weight these days.
Never had a JL anything and probably never will, but this is a nice amp. Oddly enough, I like that they don't rate it below 2ohm. I'd rather run a higher ohm load and still get the wattage than to have to run everything at 1 or less to get better numbers. Then again, for the price of this one... I could buy a bigger amp from another brand and just run it at 2.
I'll keep banging my D'Amore though since it's already bought and paid for.
Does it sound better then a Fosgate? Honestly when i have the budget Fosgate makes a great amp, right now my wallet is on a Skar audio budget but man for $500 i got a box with x2 12s and a RP 1200.1d and it hits smooth low and clear. I notice with Skar tho has to be turned perfectly it's my experience after owning 3 dif Skar amps mechanical clipping you can hear, so feed them propper power and tune them accordingly.
do a Dyno test on the new JL 400/4 amp
multiple caps in parallel allows for less resistance.....but can cost more. but each situation is unique (obviously) -JL amps are extremely well designed and very high quality.. anyone who bashes on them has no idea what they are talking about (unless its about price! LOL)
I got mine for 50$ on offer up without cover . It works
Do it bump doe?
Why didn't you test 1.5ohms like you suggested it would match the JL subwoofers?
Hey big D can You do a budget amp Viking 15000 Looking at it on Amazon just wondering what it Does ? supposedly have Brazilian Goats.??
