This is a great amp. Gave my speakers all the power they needed and some. Top quality product for the setup I have. Will continue to support CT Sounds. And would definitely recommend buying CT Sounds speakers to go with this amp. Will be purchasing again in the future

The guy that claims a super old 50w per channel amp "has more power" than this is full of it. Either he did something wrong or he had a dud (which wouldnt surprise me..). I have had three of these so far. The first was in my car, powering four Sundown supertweeters and four Skar 6.5 neos, feeding each 125w RMS. It was ungodly loud. The same setup using that other guy's 50w amp, feeding 25w per speaker, would have barely been louder than a stock stereo and stock speakers. With the CT and my stereo cranked, without considering my subwoofer even, youd have to stand 30+ feet back from the car to hear someone talking next to you. So ignore that guy. BUT. This is not a perfect product, by any means. It is VERY poorly made. It looks ok and feels well made, but it is just not. The first one I put in my car was fine. Then I bought another to make a DIY home stereo. Tow of the four channels just didnt work at all. Returned, and got a replacement. The replacement works, but has issues. Something internally is crossed and either there is channel mixing on the RCA inputs or something else weird is going on. For the money, hard to beat the power, and the SQ is decent. I replaced the one in my car with a D-6.1200, and while I got a sick DSP and far better SQ, I also lost a LOT of output volume. Even though the D-6.1200 is 200w x4 at 2ohm (I am not using the 5th or 6th channels yet), only 50w short of the CT per channel, the volume level is noticeably different. Which is fine in the end, the CT with my eight speakers was absolutely damaging my hearing before even maxing out, but the AudioControl is just barely at the limit when at max, so the smarter choice in the end in regards to my health ha. I would say ignore the bad reviews, at least if you buy on Amazon. If you dont get one that slipped thru QC with a defect, it is hard to find more power for a better deal. D4S has some REALLY killer sales lately, that give you even more power for even less money, but that isnt super common or something you can bank on being in stock anyways.

I was honestly torn when I bought this amp I’m using it to run two component speakers upfront and two 6 x 9‘s in the rear of my car. I always thought that I would need a class AB amplifier in order to get the sound quality that I really wanted out of my speakers, sure a class D amp would be fine for subs but not for the speakers. I was absolutely wrong this amp sounds great. I can’t thank the people at CT sounds enough for making such an awesome product!

I am CT sounds customer that purchased two ct amps four of there best coaxial speakers and two 10 subs .. I know how to run car audio as myself have been doing it for a life time . The four channel amp keeps clipping off for a second here and there . I’ve only owned the four channel for about a month . I pulled the amp to send for warranty only to be jerked around with questions about my installation. Mind you I have a Hifonics four channel amp that I’ve owned for years that’s actually is bigger than the CT and is in the car for temporary so I can have my music the system works fine no clipping or cutting out . I’ve spoken to Brandon in returns and warranty he dosnt care if I have my product or not it’s been two weeks and they still haven’t replaced it yet they want to test it make me wait longer again I’ve only had it a month and purchased extended warranty. So very disappointed in the way they handlel there return Or repairs. This experience has totally killed my faith in this company.

Paired with a set of Meso 6x9s and eventually a set of Meso 3 way components. Video is with just the two 6x9s as shown. Gotta say this is the best 4ch amp I’ve ever purchased. Super compact to fit just about anywhere and packs a really big punch for the price. I’d recommend this amp to anyone looking for a 4 channel amp for their car! Outperforms RFs equivalent prim amplifier and for a cheaper price and you don’t have the RF brand on the amp. Definitely satisfied with my purchase and won’t be the last of my CT Sounds products!

Was a replacement for a Kenwood amp. I have the front on 2 ohms and rear on 4. It’s extremely loud and clear. Doesn’t get hot and the clipping indicator lights are amazing. Never adjusted gains so easily before. Will never go another route for mids and highs.
