In the name of all that is holy

This thing is solid. Amazing quality. This thing is smaller than I thought but it weighs about twice as much as I expected. Solid amp. Sounds AMAZING!

She loud

I’ve got some prv 6FR200 6.5’s in my rear doors and the 8’s in my front doors and they are screaming. Amp definitely gets hot I have to get more fans on her. Speakers are bridged per side at 4ohm. Set the amp with an oscilloscope clean and still had to turn it down some. Definitely pleased just have to keep the amp cool.

Great Customer Service

I have one of the 80.4 AB amplifier.
Sound is good, power is good.
But the reason I am writing this review is CT sounds Customer service. I had the amplifier go bad on me shortly after the purchase. I checked everything on the install, even ran 3 different amplifiers on a test bench to verify that the CT was bad.
They sent me a new one with ASAP.
I am looking to upgrade my subs and because of the service I receive from CT sounds I will be giving them a shot.
