Instructions would be nice.

The amp preforms well. It hooked up to an 15”MTX square sub. It’s in a prefabricated box with a port. It’ll make your eyes water. But hooking the amp up was a game of guess what goes where. There were no instructions and no links at CT sound.


I have this amp installed with 2 tropo 12s in a custom enclosure. I was pleasantly surprised and how hard they hit. Amazing products. I plan to use meso 12s and CT 3200 on my next build. Very optimistic, can't wait

Great Amp

Great amp especially considering the price. Puts out rated power and has my tropo xl 12 pounding away.

Great Amplifier

I really am enjoying the amplifier. The only question i have is what is the frequency knob used for? i understand all of the other knob functions except this one.
