CT Sounds CT-400.1D Compact Class D Car Audio Monoblock Amplifier, 400 Watts RMS

Great amp at any price. I've had this amp for several months now. I have been using it to power 1 Alpine bassline 10-inch subwoofer. I listen to my music loud and have the gain turned up so it thumps hard. My commute to work is about an hour long every day, and it hasn't given me any issues at all; it doesn't even get hot.

First received a used unit that was missing pieces. Processed an exchange and it was delivered 24 hours later. Works great and sounds great.

I matched this with a shallow Ct sounds hydro 10in and installed in my Kenworth dump truck. Build quality is excellent and it packs a punch for its size. I had to buy the smallest 10in box I could find because I’m limited on space but it powers the sub very well. I have it on the floor which gets pretty hot to the touch from the transmission right underneath and the amp hardly gets warm after continuous hours of listening. Sound quality is great for me I used a o scope to set gains and couldn’t be happier with my purchase. Time will tell and I will report back this winter since I seen some issues with it not working in the cold.

This little Amp is no slouch, can't belive its 400 watts! Been doing car audio for quite some time...and this amp for the price is amazing. The build quality is definitely on point, its definitely got some weight to it. very small and compact can go just about anywhere. It's definitely a little power hungry...I almost regret not installing 1/0 gauge power cable and just using reducer at the amp but it's only 400 watts. Got this running 2 CT tropo 6.5s at 1 ohm and the overall setup DOES NOT Disappoint! My only Gripe (or Gripes) would be the bass knob is trash. Very cheap lightweight plastic, I feel like if you just look at it wrong it will break. I didn't even mount the knob because I'm afraid a Tab would bust off while screwing it down. It also has a power LED on the knob which is a blinding blue...I can't even look at it straight on with out it leaving a weird blue fuzz in my eyes for an hour. Other than that, awesome amp, awesome price...I look forward to getting another and strapping them to 4 6.5s 👍

Bought this for my 2009 Street Glide. Fits behind the fairing has good power, but I've tried 2 and only one channel works. would be a great amp if it weren't for that. A quick update, CT Sounds reached out, they have a few suggestions, to make sure installation is correct, if it is, they offered to warranty product. Great Customer service!
