I have been salivating at just the thought if this amp. Finally ordered 2 when they dropped for pre-order. They are goergeous and the video does not do them justice. It would have been cool to see it only on the quad box!

@murrayshekelberg9754 it's awesome I think I got pics on my community tab. I've gotta get better quality speakers for this amp cuz the ones I got can't hang

[@matthewf1979]

That is a killer set of features and power for that price! If it sounds good it’ll be a freaking steal! 20 years ago you had to pay twice that to get those features in a 50w x4 amp! I am impressed with all of these D4S JP3 amps so far. I might actually recommend these over the RF Power series amps since they have huge dynamic power(makes up for the constant power).

[@bobit8742]

awesome amp, been waiting for this review on this purple ab. You don’t disappoint

[@catch22frubert]

Definitely an amp I'd like to have in my car. Great price too. I'd like to see it stay sub $300, but either way, still a nice old school amp design and good build quality.

I love the review and thank you for testing all of JPs amps! This one will be running my tweets.

[@MannuhFestIt]

These D4S amps are gonna take over quickly. But what I kinda notice is that the “competition” isn’t the other brands that popularized on Korean board amps; it looks like these amps are the Korean version of Taramps where they’re budget friendly but just with different internal boards.

[@davidjiannotti1537]

I now have two of these for mids and highs and a jp23 for low end. Ripped out everything and in the process of doing an 8 ch dsp setup with 3 ways up front. Almost there. Amazing amps!

[@wal]

Awesome 👏

[@ssjdavid]

Do you think the 34AB is worth the extra $110 over the JP84? I’m going to be running everything through a dsp eventually

[@LunarHermit]

That thing is beautiful! Would be perfect for a set of beefy 6x9s and a 12", very reasonable price too IMHO. I highly prefer class AB, on the whole I still think they sound a bit better and there's no chance of switching noise leaking back into the rest of the system.

[@travismanuel3739]

Dude thanks 🙏. You hurt my buddies feelings. He bet me that his amp was better than mine. I went straight to your channel and pulled both our amps up. Lmfao 🤣. I’m putting out almost 1000 watts more than him, and he paid 150$ more than me. Can’t argue with the numbers

[@wal]

Thanks for watching and commenting! MUCH appreciated!!

[@RydinginStyle72]

Thank you for bringing the down for sounds lineup on your channel. I recently picked up the jp-8 to try out because I love the punch base with the voltage. I will definitely be trying out their higher power amplifiers now. Amazing the super high-quality and these things are built like a tank!!😊

[@wal]

Some people complain I show them “too much” but I believe in the product and think they are amazing price/performance

[@RydinginStyle72]

Well I can tell you I was running a taramps 3000.1 on my stock F-150 I have three 12-inch subs. Running on stock electric. I just swapped it to the jp-8. I can't believe it is definitely louder and hits so much harder in the lows! I'm getting voltage drops at max volume, not under 13 volts, but this amp rocks my stock 2021 F150. All I can say is, wow! I will be getting an xs power battery then a JP33! Down for sounds is AWESOME 😎

[@D4S-JAKE]

Thank you for another review. 🙌

[@jasx1485]

It would be cool if you made a video of this amp or another 4 channel showing how you would set up the crossovers on something like someone adding front and rear door speakers with passive crossovers

Regarding your buddies s10...My local audio shop that went out of business years ago had a black s10 with exact same tilt bed and it had 8 12" mtx 5000s if memory serves me. That picture just took me back 25 years. 😂

[@25hztolife14]

I notice no actual ratings for 3 ch mode. Ratings not posted on screen for 3 ch either. This amp can attract buyers because of its 3 ch mode; and you really sell it as a 3 ch amp as well. It really is a all in one solution for those who want to use it like that. I also notice no comment on if the amp needs more than 4 awg ofc (you used 0 awg ofc). On top of that JP had the JP 34ab on his website for a very long time but only recently changed it--he should have changed it as soon as possible. Cross over points? You talked about this to an extent; however, is it set at 12db, 18db, or 24db? Would you recommend use of the deck crossover feature instead? Lastly, I notice you didn't do a 2 ch mode demonstration featuring sub performance and your take on it. I have this amp, and it's really good sounding. I was looking for an AB amp that would give me a different sound signature; and this Royal Purple Amp DELIVERS. I use it in 2 ch mode for two 12s.

His amps are great, but he wont display negative reviews. You can't go by the reviews on his site. I left a negative review and it did not show. He only shows positives. It was not defamatory in anyway. I was just stating my disappointment in his claims considering he is a bass head guy. I was expecting a bass head speaker. I have 3 of his amps. His amps are great, but that BT speaker will never satisfy a bass head. The Harman Kardon speaker sold at the Metro store for about the same price as his speaker has a ton of bass. I will be salty about the gas lighting till the day I die. His arrogant attitude is what set me off. There is no way you ever get me to believe he thinks that speaker has bass head quality bass. How he handled me cost him at least 4 more amp sales. I go through cars like water, I dont pull equipment when I sell the car, thats just trashy. Bass head for life.

[@dextermorgan1]

He's always come off as pretty arrogant to me too. Idk if I'd not buy an amp because of it, but it's definitely a consideration. That's not cool about the reviews either. I'm glad you wrote that so people know. There's too much good equipment available today to be a douche bag to your customers.

[@JAM-ur8tj]

I was thrown off by him in one of his videos where he claimed to be the first ever to come out with a Bluetooth wireless bass knob. And he knows full well that Kicker did that with their KXA amps years ago. That shows he believes he can tell his customers anything he wants and they will believe him, that's arrogant. Other than that I hear his amps are really good.

Lets just say that I wont be getting rid of my jl audio amp. And I forget to mention that the jl audio amp is class d, not class ab like the jp amp.

Make sure you didn't reverse the polarity one one channel as that would explain the SQ issue. I haven't had any complaints and several other friends who have these really like the SQ

BigD? Did you change your microphone or something? Or do something with the Audio? Maybe its just my ears foolin me again. But it sure sounds did sound better then I have heard that track before. I noticed it on my laptop and grabbed my cans. Maybe its just me, but I think I heard details in the music tracks that I never noticed before. The First track with the piano and cymbals just jumped out at me for lack of better description. Maybe its just me? But this Class A/B amp sure seems to be musical and somehow? Provide better detail. Maybe its just Microphone placement?. Whatever. These Elacs sound great with this amplifier! Even that lazer song seems to have more details on playback. I never heard the Fuzz before in the track. I'm impressed. I have to ask you. Did you do something to the room? This recording really sounds better.

Yo JP, why can I HP @ 20hz, but only LP at @ 50hz? It's stupid, make them both 20hz!! Surely easier on design and manufacturing too. My only other suggestions would be, how about adding a 12\24dB xo switch? Also, continuously variable phase *please*. I use a 4 ch to drive a single 12", and without the phase knob, the 2 bridged channels are not aligned. Everything else looks pretty sweet!

[@bobking7347]

Its user adjustable bro.... Read the specs, High Pass Filter: 20Hz - 800Hz High Pass Filter Multiply: x1 - x10 (200Hz -8KHz) Low Pass Filter: 50Hz - 800Hz it's completely usable with that insane range

[@minus3dbintheteens60]

Didn't you read what I said? Even if you didn't, you've listed the problem yourself. The minimum settings for the HPF and LPF are not the same. 20hz for the HPF is really good, but 50hz for a LPF is crap, and *especially* at 12dB. And it makes no sense whatsoever to design and make 2 completely different circuits to make them different frequencies when it is desirable to have both filters begin as low as possible. Let alone the overlap issues that creates.

[@iang7523]

There is no high put alternator for my car so what can I do.

[@midnightsunindustries5239]

If you're limited in electrical power, consider a class D monoblock, like the D4S JP13, it is around 96% efficient at 4 ohms. At around 700-1000 watts rms, with good sub choice, they can get insanely loud and clean with relatively little amperage draw on a stock electrical system.

[@nathancotton8020]

You think this would run a pair of Rockford Fosgate P2 12” subs on two channels. They are rated 400 RMS per sub?

[@catch22frubert]

I would personally just get the JP8 and use that. Its meant to drive subs and it will be way more efficient. Big D did a video on it and the 4 channel version. Now, if you wanted to get this amp for the mids and highs, thats another story. This amp isn't really meant to power subs. Just because it can do it, doesn't mean its the best choice for the job

[@c0c0asauce]

I have had a pair of 12" P2s since 2016. I have tried them on a Rockford Fosgate P300.1 A/B, Skar RP1200 class D. Hifonics 1100.1 class D, and an Alpine T class 5 channel. Catch22frubert is right that the JP8 would be a better match for sheer output but this amp in the video will probably sound better. Just depends on what you are into. Sound quality or getting loud.
