Big bass small package

Powers my two 8” subs in a sealed box without breaking a sweat. 1 Ohm load to dual 8” subs in parallel. Plenty of easy power in such a small footprint. Love that it comes with wired remote too.

Thumps!

Got the 400 amp on accident. Surprised to find out it’s got my 2 12s thumping. Happy with this and will eventually move up to 700amps.

Perfect

I am using this to power two 6½ dvc subs with a 1 ohm final impedance. Amp handles the 1 ohm load with no issues. Because the amp was designed so well with great sound filters and controls I am able to keep these small subs right in their "sweet spot". Subsonic set at 38 hertz and lowpass at 110 hertz. Sounds great and is the perfect amp for my setup!

Very powerful, the bass knob sucks though.

Perfect single or dual subwoofer amp

Paired this CT400.1D to my Orion 8” subwoofer for my civic coupe using CT Sounds 8GA wiring kit and it’s great. Not too much punch but more than capable for my sub. Nice punch and sounds great and the cost is 10/10. This is not the final setup just a quick connect to make sure everything works but here’s it all hooked up
