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 media could not be loaded. 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!

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!

Amp worked good for a while but after about 10 minutes, went into protect mode.

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.

Compact and heavy hitter unlike other huge amps with same wattage.

I am a little disappointed with this amplifier considering I know CT Sounds makes some great products. Not disappointed due to its sound or output, but because it didn’t last long at all before it stopped working. For starters, I will be comparing this to my other 4-channel car amplifier, the NVX JAD800.4. The NVX JAD800.4 amplifier has lasted me a good 4 years now. It has gone through many long road trips, and doesn’t get hot. It actually still works, but the reason I bought this CT Sounds 4-channel amplifier is because my HPF knob on my NVX amp for my front speakers broke inside the unit, and just spins, so I can’t adjust the hz for the HPF. The reason why I am giving this CT Sounds CT 150.4D amplifier a 3-star rating is because it didn’t even last me a month. I took it on a 5hr road trip, and by the fifth hour of playing music (mind you at the same volume level I played my NVX at), the amplifier went into protection mode, and after checking all fuses, connections, and wires, the amplifier won’t work. It basically fried itself, which is a shame. So it didn’t last long at all for a class D amplifier, that’s rated at 150W X 4 RMS @ 4ohms. My speakers are Audison Voce K6 components, and are 4 ohm rated mind you. I will say that when this CT Sounds amplifier was working, the sound it produced was clean and loud, with no distortion. I was telling my friends how good my system sounded with this amp, so sound quality wise, I give it a 4.5, but it just didn’t last long at all, so that’s a big letdown. I didn’t notice much, if any heat, coming from this amplifier either, so to say the amplifier overheated is hard for me to believe. My NVX JAD800.4 amp is also a class D amp, and it puts out 120W RMS X 4 @ 4ohms, which is less than this CT Sounds CT -150.4D amplifier, but it has never given me any problems. I’ve taken numerous amounts of 8+ hour road trips with it, and never a hiccup. The broken knob on it is solely my fault because I turned it too hard and broke it inside. So my thoughts on this comparison is that I just prefer the NVX amplifier over the CT Sounds amplifier, for the ability to actually LAST! I won’t say CT Sounds is horrible. It sounded great while it lasted, but I just wish it lasted. I hope I’m just one of the unlucky ones to have a bad amplifier, but considering there are other reviews that say theirs didn’t last long either, I have to assume that it’s just not built very well. The NVX JAD800.4 amp I believe is discontinued, but it was around the same price as this CT Sounds amp. Yes, this CT Sounds amp has a higher RMS rating, but the NVX amps provide more adjustability, which is a plus. If you want a NVX amp that’s equivalent in power to this CT Sounds amp, you’ll be paying around $50-80 more, but in my eyes, it’s worth the cost for an amp that you’ll get more adjustment and better longevity out of.
