I was so impressed with my first Colossus amp, I bought another one. I have used dozens of amps from various manufacturers, and this is definitely the best for many reasons. Not only is this one of the most powerful amps (tested at 3000W at 13.4V in car) it is one of the cleanest sounding amps as well. Woofer control compares to that of high power class a/b amps. Amp has many helpful features too. The DC/Thermal/Overlaod protection keep the amp working properly during heavy work loads. The 24dB/oct crossover prevents unwanted high frequencies from reaching the subs. The subsonic filter prevents damage from frequencies too low for the subwoofer. This amp is powerful enough to push any system, whether it's a daily driver or a competition vehicle, the Hifonics Colossus 3200D is my #1 choice.

Personally i have had six different amps throughout a span of four years and nothing tops this one yet. I am running two 1600 watt 12" in a 6 cubic foot box and this thing pounds. I drive an s 10 and my back window shakes.

Great amp
