![OVERLOADED my AMP DYNO? D4S JP83 is a 10,000 watt MONSTER!! [4K]](http://i.ytimg.com/vi/_Buqewi_8lI/mqdefault.jpg)
Mr. Price certainly knows his customer base! "Under promise & over deliver" will keep his customers coming back for more! 💯%
It look like it do bumpeth tho 😊😊 thank you for another awesome review 🙏🏻
I bought one just because of this review. Thanks to both of you!
I completely agree with you, BIG D. As an average listener, I find that an 800w amplifier is perfectly suitable for my needs. While I do appreciate a bit of extra bass to enhance my listening experience and give it a more robust and full-bodied sound, I am not the type to blast music on the streets to make everything shake with overpowering bass. While that may be a dream for me one day and many others, I find that a balanced and enjoyable listening experience is what truly matters to me everyday.
I had a 5 channel pioneer that prolly put out around 5-600 watts for sub onto a ported single 12” kick L7. It was ALL the bass I needed for daily use.
@@webberfan1234 I have a Mazda CX-5 with a Bose system that I absolutely love. My upgrades to Bose's poor subwoofer was by tapping into the original Bose subwoofer and connecting it to an active LOC. This helped to restore the missing 45 Hz and under frequencies, and the results have been phenomenal, I paired the setup with a Skar 800W mono block powering a 12" Skar tube subwoofer, which produces fantastic low-frequency bass under 30 Hz. The combination of the Bose system and the Skar subwoofer has created an immersive soundstage which boosted the original bose's concert-like sound experience that I couldn't be happier with.
Original Bose had food soundstage and concert like experience, but the Bose subwoofer sucked. It is a 4" subwoofer that produces very weak bass
Should have put it on two 12s inside a car to let it bump
@@terranwallace7528 that would absolutely be crazy . The cx5 is a little small. With dual 12"s I'll be ear rapeing myself
I bet your 800 watt amp, is doing about a 1/10th of that on music.... so, do you. Like the rest of us.
I’m sitting here with my mouth open, just in awe, and speechless! I’ve come to expect ratings on the Down4Sound amps to be underrated, but this almost in the same category as the cheater amps from the ‘90s, almost. Bravo D4S, bravo!!
Thanks for testing these out Derek! We appreciate it!!!
No it isnt... Not even close to the same thing. It doesnt even double its power at half its load. (cheater). Its doing some "power regulation" . Hence it doing about the same at any load. And that, is NOT a back in the day "cheater". Also, no one on the planet cares about the dynamic test on any board. Well, anyone that knows a thing. EDIT- also, its not like JP , or anyone he even knows, designed the board. He just bought a patent that was already made, and is selling it.
@@96kylar actually, there are many who do care about the dynamic power an amp has because that really shows how an amp can deliver power for the tight kick drum bass that you feel. The better dynamic power, the better an amp is going to be able to deliver that power for those type of bass notes. Take any amp that has good dynamic power and compare it to an amp that doesn’t put out good dynamic power and you will be able to hear and feel the difference.
As far as your argument that JP did not design the amps, you are completely right. But he also did not go to some cheap made in China company to build yet another cheap Chinese amp that doesn’t put out rated power and has questionable quality. He did what every good businessman does and he found someone who designed and built a quality amp to put his name on. What is wrong with that?
Oh, and my reference for comparing this amp to the cheater amps of the 90’s was to show similarities on how the JP3 over performs, like the cheater amps did. I also did not say that it was the same as the cheater amps, I stated it was almost.
Either way you look at it, the JP3 performed exceptionally well and is a good value for the money, like most of the D4S amps(I didn’t say all, I said most). And for the record, I do own a JP8 and have been very impressed with it. I’ve been into car audio for 30 years and have had too many amps to count, but the JP8 is definitely up there with the best ones that I’ve ever owned.
@@96kylar Yea, Orion HCCA 225 rated 25W per channel. Only rated at 4 ohm stereo. But in bridged mono at 1 ohm it would deliver 400W, 8X the rated power, so not the same thing as an old school cheater amp, but about the same size and more than double the power, so there is a similarity...
NOD
Heck yea, I really like D4S amps but 90% of what I put in is around 5-600rms. Finally a mass market model that comes with their genius bass remote
Damn when I was really big into car audio in the late 90’s I would have never imagined an amp this small doing that much power and 1 ohm mono stable also. That’s crazy. Back in the day the amp would be at least the size of a skateboard to actually do over 1000 watts. Car audio sure has come a long way.
Zapo Co and US Amps, BABY!!! But they were more on the size of a surf board lol... Now Old Skool Orion HCCA and the BEAST were skateboards, lol, they were the shit!
@@Miami_Bad_Boy_BOSS Oh yeah I had a friend with 3 cerwin Vega stroker 15’s each with its own zapco amp in an extended cab S-10 back in the day. Think the amps were like 1200 to 1500 watts each and they were about the size of a skateboard. But were more long and skinny. Now you can get 1500 watts out of amp the size of a new iPad mini lol. Those 3 strokers sure did hit hard. Especially for the mid 1990’s.
@@JayP7.62 Yeah, amp tech has definitely come a long way, but the 14v 90s gear was the best
@@Miami_Bad_Boy_BOSS Oh yeah. I loved those huge “25wx2” cheater amps lol.
Also this creates a shit ton of heat almost a watt of heat for every 2 watts of output 90s amps were made with way better heat dissipation due to their sizes and could commonly run for much longer at max output than these small big power amp which are great for burps and comps but really lack the constant output power of bigger amps
I'm getting me one of these modern masterpiece to go with all the rest of my old school collection. I like it when the smaller amps put out the big butt kick in power 4:53
WOW! What a powerful little package! Thanks for the vids as always!
I like how on their website, it lists 555w output for 4, 2, and 1 Ohm. Love your content, and this amplifier is definitely very budget-friendly. I'll probably be picking one up!
Nice I've been waiting for the review on this amp, it will be great for the everyday person 👍
This is the Amp I have been looking for. 100% gonna get this one for my first system!
I have been so excited for this little guy. I was expecting 750w at 1 ohm when I saw it at 4 ohm on 13.8v I was a little more than impressed.
Just picked this amp for Black Friday for my daughter’s car. Thanks for doing this dyno it really persuaded me to purchase
😱 About the same size as a old school RF Punch 45-75. Unbelievable times for car audio enthusiasts.
Thanks Dereck! 👍👍
nostalgia. i remember rocking 4 punch 45's on 2 Generic 18's on my way to high school back in the day... Those were the times
So everyone's gonna just forgot how this claims to be a constant power amp but continues to increase power the lower the ohms so it's just a regular amps miss rated to be sold as a constant power which in fact is a regular amp with a dumber down number to make it look good... they still get stupid hot on great electrical and no clipping and weak points shine there after..
Man I saw this in my email other day and I’m so freaking glad you dyno tested it . Want to throw this in my everyday with an American bass 10 for that bump
Just got one ordered for myself thanks for the videos
Always loved the honest reviews. Little monster of an amp.
Awesome power for something so small!! Thank ya Big D
Big D, that lil D4S JP3 is a BEAST! You didn't comment on the quality of the "bump" audio, but to me it sounded very clean and well controlled. Looks like that JP3 matches well with the Kicker 12 inch. Update us on your experiences with it after you "enjoy the bumps" in your daily driver over the next few months... I wish other manufacturers would understand - produce a quality product, for a good price, and UNDER stating your RMS power ratings will impress the reviewers and bring hordes of customers.
Remember that most customers don't watch amplifier tests, they simply go by what's printed on the box. Understating power ratings is not smart for the average buyer.
Power up 💪 , more to come! Thank you for the Video!
I have this amp on two Skar SDR8 D2's wired at 1 ohm (individual sealed enclosures) in my wifes Ford escape. It definitely do bump lol. Thank you for your great videos/ information.
As allways, excellent review sir. When is that ruby red JP 32.2 going to grace your bench? Like others, i know you stay busy putting out old school content! But the JP amps are definitely creating a legacy library for the future of Old School Coolness 😎 Keep em commin sir! Best part of my CZcams viewing during the week!
Mr Price over at D4S is making some fire and always puts underated specs on paper. These in my opinion blow the other brands out of the water. Now if they upgrade the caps that would be a huge plus because you know Rockford does, but Rockford is also charging probably triple the amount for an amp that pushes this kind of wattage. What a great little amp....
That’s a heck of a deal. It’s incredible how far amplifier design has come in the past 20 years.
I wasn't expecting that kind of result. Thats a powerful amp.
But will it last ..that's the key
Purchased! D4S was super FAST shipping to FL! This lil monster should be perfect for a normal stock electrical daily. TY for the great content Big D!
Jp is smart, he is hitting crazy price points love it
Big D !! I remember when I first started watching your videos about 10 years ago… the content was so cool “old school audio” even tho I was 26 year old and car audio enthusiast the old school was and still is my thing, sad to see that your content changed completely, even when your videos are so informative the stuff you review can be found in many other channels. Keep it up with your work, hopping to find other old school channel like yours used to be… specially disappoint me the most that last videos that are all about a single
Brand.
Awesome amp . Just what i have been wanting. I nice little amp that dose great power and you dont need to run welding cable to run correctly. Im a firm believer that it dosent take a ton of power to get loud just the right subs and enclosure.
This is a fantastic amp with a awesome footprint.
Oh man I have really no experience in audio. I have seen many crazy car systems in my life but for the first time in my life I heard a good one. More felt. I didn't hear any music but I felt the bass that's for sure. That's the system I want
Those ratings are like 70's muscle car horsepower ratings. Truly astounding performance. JP continues to change that scene into such a a better market. WTG!
Thank you for the review .
I run two old 90's 450w RMS amps and two 12" subs in a large ported box and it suits me fine.
Cool little amp! Remind me of soundsteam angina!!!
I needed this amp back in 1992!
I have an Alpine monoblock I bought for $50 at a second hand shop 10 years ago. I think it's supposed to be 500watt. I was running an old Kicker L7 12" and it sounded good but the speaker is heavy and I had to pull it out sometimes to use the back seat in my truck. Front door speakers are Jenson 2 way and a basic Alpine deck. Rear door speakers are factory ones. I sold the Kicker and got myself a JL audio 10" in a box specifically made for that speaker powered by the old Alpine second hand shop amp. It hits so much harder and it's half the weight.
Good amp. Thanks.
Just bought 2 of these for my two 12 inch Image Dynamic idq subs in my C6 Corvette.
Love the old school look on the dfs amps
God damn D4S ain't playing around with their amps🔥🔊
Been patiently waiting for this video… 😁
I was going to buy a Kicker amp, But after seeing this i decided to order a JP3. Cheaper and makes more power then the other amp's I was looking at 😎👌
Nice little amp thanks for dyno video.
Thanks for watching and commenting!
Amp tests like this is awesome ....would like to see you so a test on the sound digital evo x 800 4 some time . Thanks for all you are doing.
God damn😮😮😮 this is amp is definitely gonna sell out fast. Best sellers for sure
I love my jp23 amps. I have the mono and the 4 channel.
The power from this little amp is amazing, after I saw the kenwood that was just shy of pperfection (BIG D's words, not mine) and considering that the only kenwood amp I have on my wall is a kac- 921 ( my first real amp, chariest this amp more than my Rockford 150hd and my ppi a600.2) so I said i was going to pick one up this week, but after seeing this, it's a no brainier, plus I don't have d4s amp. The link you have posted for this amp, says it can't be reached
Seems crazy to me. Would buy this any day.
Nice vid.
I like that you used a reasonable voltage... Most new cars don't even run the typical 14.1 range unless the battery is charging. Voltage is automatically dropped to the mid to low 13's for that bit of extra fuel savings.
I had a KIA hybrid that would drop the voltage down into the low 12s on a regular basis!! This is because on a hybrid, it doesn’t have an alternator. It uses a DC to DC converter to step down the traction battery power to a 12 volt power source which acts like an alternator. After some time, I discovered that if I kept the headlights on then the car kept the DC to DC converter putting out power at all times, thus increasing the voltage and maintaining the voltage at around 14.1 volts. Regardless though, it is nice that Big D does his tests at real world voltage.
Yep, on my 18 ford escape, the alternator starts up on 15v cold start but once it gets warmed up and detects the battery is charged enough, the voltage drops down to low 13s
I'm getting a new car soon and was thinking about getting this to power my 2 kicker VR 10s. Now I'm sold, D4S rules!
For the pricetag, that amp is crazy :)
How have I never heard of this?? Thanks for showing it off Big D! Toss in some proper caps and a high-flow fan for not a lot more money and that should last long enough to rumble the car apart. 😅
Wow phat little amp you got there!
I am running a JP63 extremely powerful amplifier, the most powerful amplifier I have ran and I also own a Deaf Bounce AAK 4k & Soundigital EVO.2 12k. However the only two drawbacks I have noticed is the issues I have had with the Bluetooth knob randomly not working. Also the amplifier does not have enough thermal Mass for the Heat dissipation by the mosfets even in 80 degree weather it will quickly rise to over 100°F now this us far away from the silicone breakdown temp however a bit warmer than I would like to see it on average operation and it is far away from clipping. The onboard fan will only minimize the heat creep but can not cool the amplifier they should add another fan to the larger boards
Those ole Kicker Gold letters was the champs!!!!👍👍👍👍👍
🤯wow that’s great
King of the budget amps a must have.
Very interested in gear like this. I have to use ALL the cargo area in my Jeep for... cargo, but I want to upgrade the 100 watt "500 watt" Alpine system. These smaller amps are the way, methinx. Seems like we're in a golden age for car audio, right now. Which is interesting since car manufacturers are trying REALLY hard to keep us from buying aftermarket head units.
Insane value. D4S for the Winnnnn!!!!
Could you imagine having amps like this in the 90's
I like the small size of these, however the longevity factor really boils down to that price point. Can totally see these amps cooking themselves!
If this amp does like the larger JP8 then the fan doesn’t even come on till higher temps are seen. I have the JP8 and with running it at 1 ohm at close to clipping for 30 minutes straight, the amp would heat up quickly and then stay at 115-125 degrees. This is in Texas in the middle of summer where it was 100 degrees outside. Hopefully, this little amp handles the heat like the JP8, hopefully.
Heh, reminds me a bit of the old school Fosgate Punch 30 from the early 90's..
Not near the same power as the amp here, but was amazing none the less back in the day.
This is exactly what they needed to make me a customer. :)
Can’t wait for a JP13 review!
This one will be on Williston Audio EXTRAS, make sure you're subscribed 👌 czcams.com/channels/gz8QirXKO5EPWH6sV-hKlw.html
seen this pop up a month ago on d4s .. was wishing you'd do a video .. i figured the 555 at 4 vs 1 was a lie ... love to try this with my two kicker 8" . be a upgrade from my 250w taramps ,,
I really wish D4S would start listing the db/octave in the manuals. I can't find it anywhere.
Did you test 12v back chance? Curious if the power supply makes a big difference at that voltage as well
Wow what a awesome little guy. I wonder if there is a 4ch in black.
Damn that acrylic Gatley box is getting all chipped up around the sub. I know you've had a lot of subs in and out of it, but damn.
That's what I was going to say, but you beat me to it. The epoxy on the threaded inserts could've lost the bond, and the vibration caused some stress cracks around the holes. I've been wondering how much abuse it could take before bonds started breaking. It held up longer than I thought it would
I think when I tried the Massive Audio BOA121 sub in there, it really stressed it out. The cut out wasn't quite big enough unfortunately
That Boss is rated for 20w x 4. Lets say it does a clean 15w. This means it should play well at low to medium volume levels, but at higher volume you'll hear distortion. More power will only allow higher volume without the distortion. So if it sounds bad at low to medium volume, an amp is not going to fix that.
What set of speakers do you have and are you using the passive crossovers that came with them?
Where are the speakers installed.
Can you describe in what way it sounds bad?
Damn now i gotta upgrade my remote wire to 8 gauge
😮 THAT LITTLE AMP PUTTING OUT POWER
Everyone can make play louder, the harder part is how really accurate is the detail to the rendition of the bass. The acid test for lows is the Double bass instrument.
It's awesome, the only concern I have is the amount of power going through such a small amp. I live in the desert, it gets hotter than a rattlesnakes taint during the summer.
Ask Big D to document ambient rise over like 20 minutes and then calculate yours from that.
I don't think you really should worry. The heatsink on this amp does its job and while it'll get hot, those internal parts are all rated for 85-100C. You should be just fine, especially if you run proper voltage. Adding an extra 140MM fan to the mix to move air across the amp won't hurt things, either.
Just put additional fans on the amp. Problem solved.
It has a built in fan under the plexiglass cover.
Good lord. Nice option for the bike
Big power in one hand.....💪
The fact that the output stays similar in lower ohms means that it has quality chips in it keeping the protection walls up I really love the fact that JP is choosing quality over quantity This amp is perfect for a beginner or just a regular base lover with 2 500 Watts 800 peak kicker vr 12in perfect set up to run at 2 ohm
Keep in mind that this amplifiers constant power design is different from most amplifiers and that's why it has consistent output. It has nothing to do with the quality of the chips
@JasonWW2000 lol still goes back to the design of constant output under stress loads thats where weak links fail... i.e. chips and circuit design... im into electronics and amplifier repairs.... my comment was directed at jp's choices...you could have a cheaper version of any of these components and have different parameters of functionality (like when turninig on and off)voltage regulators. sot23 ...ceramic resistors... zn44 mosfets... filters.... pnp's....rectifiers...npn's you think none of these are in a constant output designe... but thaks for chiming in... at least theres discussion, learning, and growing in the community follow barevids he repairs amps
@@johnpolaski6126 I'm glad things are more clear now. 👍
@@johnpolaski6126this is just a simply mini Chinese class d all class d d amp dona certain power like 550 at 4 ohm 800 at 2 ohm and something like 1k at 1 ohm . Jp just markets this amp as 555 in all ohm loads Wich is kinda.silly.
Impressive!
I may order this one.
The thernal imaging you did..was the amp laying flat on the table? I noticed the fan on the cover. Bet all the heat could have been less if the fan opening wasnt blocked. 🤔
I am on the fence about this amp. I'm not sure it would act different on some subs with the changing Ohm loads, but this amp should have a tighter clamp on the power at lower Ohm loads! We all like more bang for the buck, but I think an amp should be rated close to the numbers posted. Like that crazy Orion 2500 hitting more than 10k in power. I would like 2 of these amps on my pair of 8s, but with it clamping so high at 2 and 1 Ohms, it has me hesitating I don't want to re-cone these subs every month because of miss rated amps.
Hey have you ever tested the Sony XM-5ES 5 channel amp, looks to be a really nice amp but haven't seen much about it on CZcams
It's amazes me on the power per dollar that's available now a days. You could spend 3k and build a killer system
Lmao...🤣🤣 You included the clip of that flamboyant guy with the car. "Would ya just look at it?!"
Good video, it will be possible to make one of the company CT Sound, and your opinion if you recommend them.
I’ve tested a few, here’s one
Bass Amp for the Masses? CT Sounds CT-400.1D Review and Amp Dyno Test [4K]

Id upgrade that fan to a noctua to keep it cooler and quieter. In the pc game theyre king. The bequiet! Silent wings 4 are also a very good choice of pc fan if you can manage to fit a 140mm fan.
13123watts for .5 dynamic with no protection , is still the craziest dyno I’ve seen you run from orion 3k
What do u think about this amp on a gately audio relentless 6.5
Do you have a good way of removing magnets from old subs and speakers? CZcams need a video on this. 😅
How's this working on your daily? And which ohm do you use in your daily?;thanks in advance
I have come to favor audio control lc1.800....underrated and superclean output worthy of Sq duty..it's a bit pricey but I think worth the money
Ran two Fosgate p3 dvc 10 subs and it was all they wanted maybe more
nice little amp
I like these D4S amps. I'm replacing 2 Punch 150HDs. BTW what is the intro music on this video please?
Song is "Low" by NEFFEX and is in the CZcams Audio Library
Nice
NICE MINI MONSTER
The Kicker 800W is in clearance at Best Buy for $127
I just bought one, thinking I should buy a few more 😅
