Customer Reviews
I’m just a grandpa that likes to jam. The CT 400 fits the bill.I don’t need a lot of power. If I can catch a 4 channel on sale I’m probably get it
Just installed this one on a JBL Club 10" in an explorer and she is way stronger than the ratings. Great build quality and sounds awesome as well. The small footprint makes it very versitle as well. Great job CT Sounds.
Love the amp it’s great
CT-400.1D // 400 Watts RMS Monoblock Car Audio Amplifier
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.
