Power From the Gods!!!
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.

Awesome for the price
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

Bang for your Buck !!!!
I am running 4 Clif Design 12's 4ohm DVC rated at 800 watts rms.I have TWO sets of two subs with the DVC's wired in Parallel, with the subs wired in Parallel as well per channel.Each channel is pushing 1200 watts rms! This amp gives you several channels at different ohms to power your subs.That is y i rate this AMP as excellent and very user friendly for the do it yourselfer!The price is very well worth it.
