The MOST POWERFUL 7 Channel Car Audio Amp EVER?

[@SchClean]

[@brotharobmusic]

That guy is brilliant! I enjoy watching him repairing amps!

[@dead6last]

yep he is awsome

[@THELIFEOFPRICE]

So stoked about this monster 7 channel! I’m glad you showed the history of the 7 channel amps so people could see how BIG BOY THIS IS. BIG POWER AND BIG VALUE! Y’all be sure to use his affiliate link when ordering! Hhmmm which amp should we get Jacob Scott to create next?

[@CL-yp1bs]

There is NOTHING like this on the market. I am a long time car audio fan with deep knowledge of brands all the way from skar audio up to fancy stuff like mosconi, focal, etc.. There is literally nothing like this that i've ever seen. There are several 6 or 8 channel amps.. but none of them have any decent power on the sub channel. I am a person where 1-2kw will do it for me.. but i cant stand using a amp with only 500 or 600w on the sub channel. I dont even need an amp but I am probably going to pick one of these up just to keep on hand for my next build i do. Once these sell out, it will be hard to ever find anything like them again.

[@wal]

Thanks for the feedback!

[@msh6865]

I'd like to see Sam go over this amp from stem to stern. Maybe test the amp for THD at rated output as well. IMO the real turning point for these D4S amps will be if/when someone uses one for a competition SQ system....and is at least competitive. We hear all the time that the amp is the least important element in a true SQ system. Well, this is the perfect amp to confirm or disprove that claim. Excellent overview and dyno video Dereck!

[@wal]

Thanks Mark. I don’t think SQ judges would appreciate a D4S amp but maybe they don’t look or care about the brands…or maybe…

[@barelysarcastic73]

⁠@@walJust getting around to this video (must have missed it) and imo if a judge needs to see a brand to be impressed, they’re not a real judge and should have their creds yanked.. especially for sq. Either it sounds good or it doesn’t. Agree with Mark 1000% on having Sam go over this amp in detail. I want to do an OS “themed” build in my ‘87 Tbird and this amp would be perfect. Outstanding video as always Big D!!

[@EZShop76]

Awe man, I was hoping to see the sub channel in . 5 ohm. Still plenty of power. 😎

[@wal]

👌😬👍

[@StockA4]

UPDATE: Before I got rid of my Kia, I ran this exact amp^^ for a couple months on a Sinfoni Tempo 3 way set, and a Savard Hi-Q 15, (signal processed by a Helix Ultra). I have zero complaints about this amplifier. It did everything I wanted it to. I just plugged it into the system and ran everything at zero gain, (because I didn't feel like measuring, or messing with anything). This thing is stout, and treated all of my speakers pretty well. I was considering selling it to help fund my current build, but after seeing it in this video again, maybe I'll just hang onto it. It's a solid piece of work, so far.

[@DIYAudioGuy]

I think I found the perfect head unit to go with this beast!

[@wal]

That one is interesting for sure!

[@erik120719]

Never been a fan of JP but this amp is legit, whole car power for what alot of guys spend on just a monoblock. Will be checking one of these out next time I need a full car setup for a customer for sure

@@ksavage681 never really dealt with any of the d4s products but def will check em out

[@00000005547]

Not trying to downplay the amp, because it's still impressive, but what would make you choose this over say, 2x Taramps DS 4000x4's which would give you 8kw rms vs this one that does almost 4k? Looking at the components on the outputs this is also a class D so sound quality should be pretty much the same.

[@erik120719]

@@00000005547 bc taramps are garbage for both SQ and build quality. ive run half the power of the taramps in exact setup , played deeper and louder. ive put many taramps in bike installs with PA stuff and SQ was junk, it was loud asf but that what the customer waz looking for so it served its purpose, for me, the wont ever be a brazilian amp in my vehicles ever again. the md8k was flaky, didnt last long, got excuses from customoer service, and was told it may be almost 4 months for repair...threw in garbage and replaced with a cheap rp4500 and it WAY outshined the 8k in both loudness and authority down low.

[@josephrodriguez5566]

Big D, Yare the man all your testing on these amps. I just ordered it to replace my JL AUDIO AMPS. They do not last that long. I wish Linear Power were still around. Those are what I competed with in high school and still using the 2.2 high voltage and 5002iq running my two jl 10s under the seat in one of my crew cabs. If I could, I would pay Linear Power whatever for a 6 channel or 7.....Keep up the awesome testing...old schooler to another.

Been watching for a cpl years now but I don't post often. I would Love to hear Sam go into more detail on amplifier designs. And not just the JP. I'd be interested in that collab going over the details and nuances of many Quality amplifiers such as JL, RF, Kicker, and maybe someday look at some European SQ Amps like Masconi and Zapco. That would be an awesome series I think we'd all learn from.

The only gripe I have about these amplifiers is that if I wanted to build out a system, I don't want my amp wall looking like a rainbow.... wish they all came in the same color.

[@ua7pyro591]

Yeah, weird flex for sure. It certainly screams cheap.

[@ericperry72]

Exactly! Pick one basic color and then charge $50 extra for different colors for example

[@wal]

It’s a personal preference thing for sure

[@csj9619]

Word

[@vipersb1]

I like the colors they're using, but wish you could order any amp in any color. Would probably take longer to get them in a custom color, but the option would be nice. Maybe they'll start doing that at some point, I can't imagine it would be easy to do from a logistical point.

Wow. 1.21 gigiwatts! Very nice. These are pretty nice amps. Sam is the man! Great job

[@majorbarnes4090]

That is a special Amplifier. Big D, I bought some subwoofers from your brother in Virginia a few years ago. They are some 10 inch subs in a ported box. Yall look alike and I told him I be watching your cool videos. "This is not a mickey mouse program"

[@1ohmwrecker]

"Skar will only get you so far". They never come out with anything new. I got love for them cuz they got me back into the hobby, but you can outgrow them. Plus the permanent protect problem they had with the RP2000.1D's, and me having to exchange 4 of them to get one that works correctly, that wasn't fun to deal with. Although 3 yrs later, I still got it and still works🤷‍♂️

[@Outty5000Hertz]

Now D4S totally dropped the ball without adding the tweeter crossovers cause I totally intended to use this amp as a one chassis solution for a complete system

Here I am considering this for my truck... Upgrading from the stock 95A alternator to a 370A alternator. Not planning on pushing this to it's limits (power output wise), but utilizing the number of channels (set for the tweeters, set for the front woofers, set for the rear woofers, and another for the sub, DSP/EQ controlled, ~1100W RMS combined going by rated RMS of each driver).

Running RF t5 3way front and a SMD mini 12 inch sub all processed through a audiocontrol DM810. ..my 20+ year old 225.2 is causing a whining noise feedback into my other amps at zero volume.

[@dustinschimkat8645]

Wow what a amp beauty

[@CL-yp1bs]

Rockford has had amps with massive dynamic headroom for years. This is indicative of a well designed amplifier. When there are big or loud peaks or transients it means the amp can supply the power, instead of falling on its face. I would say it likely sounds very good, i am very impressed with the feature set on this. Most amps with this many channels have very low power output. The SQ folks will love this one.. running active with a DSP, this is a one hit wonder for running a 3 way front stage and one or two 12-15" subwoofer(s). Pair this with a 8 channel DSP (cant find a 7 channel) and you will have a killer system.

Great looking amps coming out from Down4Sound. I wish they had been around when I built my most recent system. The pricing for them is great but I wonder how long they can keep it up. Many times new brands are priced for low/no profit to get market share and many don’t make it past that stage. Skar walks the pricing fine line with their sk series korean amps while DC has gone upmarket with their korean amps. It will be interesting to see where Down4Sound is with their amps in a year.

[@jimjones3287]

I don't get why this guy has to crap on Skar audio to promote D4S. Both companies make good products for people on a budget. D4S has the lowest tuned pre-fab boxes I've seen on the internet at 32Hz. Others say 35-38Hz but are clearly in the mid 40's. The Skar prefabs are a true 38Hz which is good for all kinds of music not just songs with processed basslines.

[@2011joser]
