Since JP brought back the classic US Amps heatsink look, it would be cool if he also brought back classic sink links to make two or more amplifiers look like one single long chassis.
Man i wish amps like this were available at this price point back in the 90s.
Well, there's a reason amps were expensive back in the nineties, they were better built, class a b, and made in the USA with zero tolerance components.
I would have been deaf for sure lol.
Technology moves forward over 30 years, they'll be saying the exact same 30 years from now.
@@danielknepper6884 More like needlessly overbuilt but inefficient and weak. Technology and innovation buries things that are meant to be put in a museum for a reason. 30 years later these korean amps will be put in a museum as well when new innovation comes forth.
@@Jeffdachefz ok buddy. Lol
I regret buying the Memphis 1200w 4ch brand new and the back speaker channel doesn't work A and never has only front and subs work. It only pushing 2 400w 6*9's and no clipping issues....yet LoL
Man another great review! Sounded amazing on the sound demo as well 💪🏽💪🏽And as always we take your recommendations on ways to become better seriously so thank you for that 💪🏽
Good shit brother 👍
I appreciate the opportunity to test as well as provide feedback. It’s getting harder and harder to find negatives 👌
@@wal that’s our goal 😊
@@wal You should review their customer service. Their anti-consumer return policies would make for a riveting video.
@@scottjames3698 well the name of the game is not to accept returns, the name of the game is to sell sell sell sell and move it out the door.😅😂
Down4Sound is really making an impressive mark in the mobile audio sector with these new amps.
I hope to see the high quality continue at these incredibly reasonable price points.
Thanks BigD for sharing your knowledge and thoughts and helping us know there are some fantastic options other than the mainstream stuff we've all heard about.
Wow 600 watts at 4 ohms on each channel that's one of the most powerful 4 channel amp I have seen in a while for all those guys who want to run high power midrange while keeping it in stereo mode
I'm using a 4 channel ol school Earthquake TXO4300 on my 15" subwoofer right now and it flex my car running in 4 ohms💪💯
I listened to this on my car system my man. It sounds so good on it. Thanks for sharing and testing of the amp.
Ow i love watching when you test in dyno and excited to see inside the amp.
Always tune at your channel watching from Philippines sir.
Dude that things a monster 4ch! Like you broke out some og royalty with the w7! Man from watching your ch so long it’s brought my insane love for car audio and slamming bass back like I’m 17 again 🤘🏻🤘🏻🤘🏻
One of a kind 4ch amp with the clip out mode awesome
Very nice as usual,thanks for the dyno vid big D!!
Wow another awesome product from JP and Down4Sound
Thanks for the great reviews
Sorry to say that im just now finding your channel.. i was a big basshead from mid 80's through the 90's . Now having a mercedes sl550 ive been researching the heck out of everything and these amo dyno's have helped tremendously.. Being out of the scene a good bit , i bought a couple of Blaupunkt amps.. i was like damn these should be so much louder. Saw your dyno lol.. man was i pizzed off...But anyway , your efforts are appreciated and very helpful
We live and learn
Yeah, blaupunkt aint what it used to be anymore sadly enough.
I can't pull myself away from using old school PPI amps. If I were too, I would use D4S amps.
I. too, love the old PPI stuff. I have no use for any of the Asian made products available
I myself are still using 4 old school linear power amps for mids and highs and and 1 for my subs. use to compete with them and never broke down. two 3002, one 2.2 hv, one 8002sw for two 12s.
@@josephrodriguez5566 Those are great amps as well. Very well made.
Trying to find more😅😅
Another JP monster. JP is killin it. Been watching both channels since the beginning. JP - We need a JP234 in Blue to match the Blue JP23 v2. My OCD can't handle the different color amps. Would have bought them already. Will be my first build back since 2003. Life got busy / got older, but still love a car audio system done right.
Yeah hes killing it but let's see how many of these amplifiers make it as long as a Rockford or a kicker. Let's see if big d has any of these amplifiers on his wall in twenty years. They will be sitting with the boss and pyramid. What is the length of life of these ample of fires for real? Why does he have to make new designs so quickly so fast what is he hiding? If you made your design good from day one you wouldn't be updating your board you wouldn't be updating the Process. It would already be set. So i'm saying he must have cheated in the first stage's. He just didn't tell anybody and he had any returns and warranty claims. Let's see that paperwork jeffrey!
i have 4X JP234's and 2 JP83's on a DSP i pulled them apart and had them anodized in Deep purple to go with my rebuild
@@MacNifty - you make some valid points. I give him the benefit of the doubt until proven otherwise. There is always a rosk in buying anything. Like any new product you always see room for improvement. With large companies it take more time for them to change. Being a smaller company has its perks and allows for updates to done quicker withoit red tape. As long as things are improving the customer wins in my book. As for the longevity that is a tough one. Most products today (cars included) do not last as long as older models. Most items are throw away and meant to last just past their warranty. Sad but true in my experience. When companies over build a product the warranty usually indicates that. In my case I am lookong for a couple years of usuage. Anything more is a plus in my book. By then things may have gotten better technology wise. I would like the choice to upgrade and not be forced, but you don't ever truely know unless the warranty backs it up.

I love your microphone. When the music is playing I cannot tell that the music is playing through your microphone vs just directly on youtube. I use Klipsch stereo speakers with a sub on my pc.
Having both input and output clipping indicators is sick, makes for much easier tuning. Although I wish it was class AB, my Orion can do 450wrms x4 @4, and it's not even the big model.
Love your videos. They are on point and always relevant
Thanks for watching and commenting!
@@wal always a pleasure. Been a fan for a few years now. Your Definitely my favorite you tuber.
Big d. Man I wish you had some kind of searchable index of all the amp Dyno videos. I would love to search for 4chn amps and really see back to back the ones you've tested
Jp definitely listening you😊
Better caps next time 💯 🎉🎉
That amp is a beast... I see a ton of blown speakers in the future 😁
The THD lights are cool and I know Rockford Fosgate has them on some of their amps.
Always wanted to get an amp that had those but I hardly use more then 20w on my 4 channel amp with my habits.
Great dynamic headroom, indicative of a overbuilt amplifier! As for the caps you would be surprised how good some of those Chinese caps are.
The Eton Core which is an extremely high end SQ amplifier with the lowest distortion of any amplifier in the world… It uses Chinese capacitors (Yuscon but it’s Yuscons high end line) so I think that is a good example of the Chinese making quality components.
To get Genuine nichicon capacitors, you have to import them from Japan into China for amplifier assembly so it’s not just the cost of the capacitors its the cost of importing them instead of buying domestically inside of China.
I would guess it would add a solid 20 bucks if not 40 bucks to the cost of the amplifier
I understand what you are saying but I don’t want people thinking this particular amp is made in China because it’s not. It’s Korean 🙂
they fixed that issue by labeling their shitty caps with nichicon labels on it. thats the real issue.
@@THELIFEOFPRICE Good to know!!
Yes and some of the ultra budget amps I've shown have counterfeit Nichicon caps so that wouldn't be helpful either. I just brought up the point for discussion. It's in no way a D4S issue only as most of the big MFG's use these generic style capacitors.
@@THELIFEOFPRICE I haven't had a good experience with the filter caps
Hell yeah! Very nice amp and love D4S
Man that amp is a beast
This would be a great head to head for the OG Rockford Power 1000 Just in terms of SQ and Power output etc.
Wow that is the most craziest 4 channel i've ever seen. Awesome
I really enjoy your channel. Especially when you do old school amps. I prefer old school installs rather than today's bass heads. I like the hidden wires and amp looks. Also I prefer sound quality over windshield shattering bass.
Thanks for the feedback!
I love your suggestion Big D. We should have a choice. Better caps for a long life. Thanks and I hope JP listens.
Wow, what a beast!
Absolute BEAST
It is a MONSTER and headroom for miles
😊
I couldn't fathom running that much power to my Highs and mids😳But for the ones who do 💯👊
Thanks for sitting it next to the jp 33 I was wondering if they matched 😀
Loving D4S Amp. Got myself D4S JP33! Right now have it running at 4 ohms on four Savard Hi-Q 6.5" subs in a custom box I build tuned to 30hz. Saving up for some Savard high out put 10" subs.
Man I bet that sounds really good!!!
Those Savard subs are killer too 🤙
@@FLINTmitten810 yea I have a slowmo video of the flexing my window and mirror.
That is just mind blowing
This amp is a beast 😮😮😮
When i build a new system im really considering doing an all D4S setup.
I enjoy my JP23 😮 it's bridged mono in the wife's mazda tribute going to 15 earthquake. Thought of trying it out on my soundstream splx...... yes the old school beast still lives. Lol 😊
JL for the win on sound quality
Can we get an updated on what you did with the skar 18" subs. Thanks Big D
I'm looking at the jp95. Question is. Can you run the front channels at 4ohm and the sub channel at 2ohm? Thank you. Love your informative videos.
Just ordered a box and amp from them. Delivers tomorrow.
Excellent amp
I would be very interested in you doing a write-up/video on the type of sound proofing (and overall setup) you have done on your Sequoia, as well as I'm sure others are interested in your other vehicles as well.
I've had my Sequoia for about 2 years now, but I just recently bought myself a nice system and I'm not really looking forward to dealing with all the rattles of an 18-year-old vehicle. 😂😂👍
QUESTION: If amp gain is set using a test tone to zero clipping, but shows light clipping while playing music loud; does that mean the gain is too high? Is that the difference between certified and dynamic? Amp in quest is the Rockford Fosgate R2-500X4 with clipping light.
I ordered a jp23 refurbished amp. Removed my ctsounds ct1500.1d amp that has been faithful for 6 months. Slide the jp23v1.5 in its place, checked preamp voltage, im running oversized 1/0 ofc wire, 2 agm xs d3100 batteries. The amp blew a cap on the filter side within 5 minutes of me having the amp. Thankfully the bottom is clear and I took a picture straight out of the box. You could see the cap was leaking when I got it. So I had to send it back the same day I got it. I have sent it in and I am waiting to see what they say. I was told they would replace all the caps. I wondered why they didn't use better caps myself, the filter caps sax 25 volt caps are only .08 cents each. I trust down4sound will take care of me. Just sucks I waited a week for the amp then had to ship it right back to the repair department. I asked if I could pay the extra money for a new amp and was denied. The listing stated 1 year warranty but it only has 30 days. I'm frustrated, but as long as they make it right is all the counts. Customer service has been great to work with, he is polite and patient. However, he can only do what he is allowed to do. It's up to the company to inspect products and step up when at fault.
Nice test. Does anyone make components strong enough for this bad boy? Lol
Legit numbers right there. 💯
Enouph power for the most and a clean design... in and outside.... not bad 4 a muscle maniac😎 👍🆙️
Big D, I know you normally do dynos on Big amps but please do dyno on the jp3 I'm curious the different wattage on 1,2,4 ohms
Like the new distortion indicators. New. 😮.
D4s always underrate their amps tho
What are the good Caps and can they be changed out? I was thinking of soldering in good ones if I get this amp.
As for better caps, they could make it a special/limited edition of 250 or 500 units. I dunno how much better it'd make an amp in this power range but it'd certainly be interesting to do a head-to-head. (D4S might have an arangement with their supplier that doesn't allow this subisturtion or makes it prohibitively costly) I suspect you'd need to do more than just a brute force output power test. Fidelity in, versus Fidelity out, dunno what test equipment that'd require though so perhaps it isn't a practical showdown.
Whats the dampening factor on these amps? Definitely need 105°c caps
Power extreme!!! Crazy!!!
Thanks.
So as always JP under promises and over delivers. God that current draw, holy cow! Definitely need an upgraded electrical and probably second battery to run this amp!!
Yeah he’s really flexing his OG status in the car audio game & giving us one hell of a deal on great amplifier’s amongst other products.
Is the bass knob Bluetooth or does it have to be linked directly to the amp I recall some of his knobs just needing a power supply and not strapped directly to the amplifier itself
Ok I plan on running this amp with 2/0 ofc power/ground wire from primary battery to secondary battery and off the secondary with dual 1/0 ofc power/ground wires to amp is this enough to run this amp ???????
About the sub, like how dose it work because I seen some with the screw holes under the surround
Everytime the dyno stopped I said gahhhhhh damn 😂..you have tested more powerful amps but I was not expecting this
🎉🎉
@THELIFEOFPRICE excellent way to bridge the gap between the 234 and the 10.4
I have no personal opinions on JP, but he seems to be killing the amp game. Agreed better caps and a dimmer for the remote would be a nice touch.
JP and his team are bringing out great products
We already started dimming the displays on the new runs of amps with the knobs 😊
@@THELIFEOFPRICE Do green or orange displays instead. :)
Oh orange and dim ftw!
Hey do u think this amp would be good for a Mtx thunder 9500 ? I’m trying to find a amp that would make it hit harder.
With music signal off and volume off, can someone tell me how much hiss you can hear coming through the mid range or tweeters? Thank you
@THELIFEOFPRICE Maybe build a Sound Quality line that includes high end caps and filters. Obviously, prices would reflect better internals but it would be a great option!
Samyoung caps are actually decent. The company (Samyoung Electronics) is run by Nippon Chemi-Con and has two manufacturing locations, one in Korea and one over at China (excluding Chemi-Con). The caps are pretty much identical, series matching but with a different brand. Their selection probably isn't broad enough to satisfy this amp though. Otherwise, one hell of an amp!
Pretty darn neat I mite get one of these. Far out man.
Reminds me of Sherwood the side of all the adjustments
d4s putting in work! they are lessening my fosgate or nothing view...good job fellas 👍👍
These days, brand name is unfortunately irrelevant cause everybody cutting corners
Awesome.
D4s has quickly become my favorite audio supplier.
Thank you 🎉
Why?
@@THELIFEOFPRICE Just recently bought your line level converter and a Deaf Bonce amp. Excellent stuff!!!
@@kiklop8362 I bought 3 d4s jp23. They pull a lot of power and sound great. I have them hooked up to 4 Rockford Fosgate 12" t2s1. The company helped with the setup and gave me advice. Which I followed. Best sound system for me yet
Same
My JP 10.4 does not get warm. I tried to see how hot I could get it, 106°F was as hot as I could get it. My Orion HCCA 11000.1 gets a whole lot hotter.
can you try a kenwood subwoofer?
Loads of power
Sweet!!
I wish they would put better caps I’m on my second JP 234
Nice!
We'll like to see another test of the Amp with lithium bank asap.
🙄
You should do a review on the kicker solo x 2023
Oh man hopefully soon!
Ummm taramps has had multi-color clipping indicator lights for ages brother the clip light turns orange for a soft clip and then goes red when you're in a hard clip scenario same bulb...
Back in the day, 80’s and 90’s, an amplifier with this type of power would have cost well over $1,000!!! I remember my old punch 150 amps were $500 each!
One amp to do it all 🤞
Like the ring 💍
Hoping JP drops his JP3 300 watt mono block amplifier soon.
That one looks super interesting 🤔
Supposed to be here this week if no delays happen 🙏🏻
@@THELIFEOFPRICE Awesome, thank you for the information JP. Can't wait to get a couple for myself.
Can you do one on the Phoenix gold Ti3-1600 I know it’s an older amp but very interested in this amp.
He only does JP amps 😂😂😂 jk
Down for sownd has been crushing it you 2 have changed the game!
💪🏽💪🏽
lol this sounds good on my computer speakers... but what about people watching on laptop or phone ?
minidsp 2x4, polk in wall 6 inch component set on new old school receiver/amp, svs 400 watt 12 sealed.
They are missing out!
at 2:00 Id like to have better QC for the freq adjustment on ch3/4... thats $249 quality, lol
You found the beef!
Four channels of FURY!
Apparently so did my ex-wife😂
If it's in the price range of a Rockford power series. I'll go with the power any day twice on Sunday
Kind of looks like the ppi logo with the lightning bolt. On the board.
It's nice
How it can handle 1kW heat?
Yessir 🔥
I was going to buy one until you mentioned it needs better caps. Thanks for the heads up
The caps on most big brands are generic like these. For most they will never experience issues with them. Brands like Nichicon, Panasonic, Rubycon, etc. are used by techs and have lifespans of tens of years. You won't find these caps in virtually ANY amp under $2000 due to the added cost of integrating into the manufacturing process. My mention wasn't to say they are "bad", but simply a recommendation to make the amps even better than they already are 👌
If anything happened you have warranty so don’t worry 😊
Higher end caps aren't going to make any difference on the rail voltage. It's the signal path where caps will shine. Also remember, there is much more to a capacitor than a name. The specs are not the same on all caps. Nichicon and other manufacturers might not make a cap specific for the needs of a particular amp or other electronic devices.
Then you need to have deep pockets if you want branded caps.
Probably cheaper to just upgrade them yourself to branded ones if they ever where to give you issues before you stop using the amp, which will probably will happen much earlier 👍
Can you do a Crescendo BC-8K??????
What's the name of the company that builds their amps??
Sony XM-1ES ?? How good is it
