CT-400.1D // 400 Watts RMS Monoblock Car Audio Amplifier

Walter Paz
Well Built

Well Built. Small and very responsive to a pair of TROPO-8" subwoofers. I have in very low settings with limited gain as they are not my primary subwoofers. to date, the amp has been holding up very well.

Bang for the buck

Was wowed by the performance of this amp. I think it's way underrated in power. Used it all day at 1.5 ohms, never got warm.
Clarity very good also. Very impressed. I'm not impressed easily. For the price, don't sleep on this baby 1 ohm stable amp.

It's all of 400 watts!!!

Awesome amp! Excellent build quality and plenty of power. Have it hooked up to two Bio 10s4's, wired at 2 ohms, inside 1.6 cubic foot box tuned to around 37Hz, I'm not even use half of the amp's potential and they hit sooooo nice! I love CT Sounds.
