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

This thing runs my single ten-inch Kicker Comp R and it just thumps. It's a great little amp. I'm sure it would run two at 1 ohm perfectly too.

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.

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.

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 👍

After 7 month of used it stopped working. I tried the second speaker channel connection but it does not work either. Its lifespan is not what you would expect.
