crazy amp

this amp is insane.. how many 2 ch. amps do you see pushing over 1000 watts a channel? this amp is perfect for 2 insanely loud subs like a kicker L7 or a mtx 9500 or an RE XXX.. i would suggest getting this amp for anyone who isnt looking to blow 2 grand on an amp(s) to power their subwoofers.

FYI

I don’t quite have this exact model… I have the older Generation XI COLOSSUS !!! & it’s quite powerful… I can’t even explore the amp’s full potential (because my subs can’t handle it… & my charging system won’t be able to keep up). I had it hooked up for about 2 hours, & it played loud, clean and powerful… I had it hooked up in stereo @ only 4 ohms each channel… & it was more powerful than my 1200 watt Class D JBL BP 1200.1 I had it on before I got this… if you want to not only be the king of your town… & want to humiliate other’s… then this if for you.

Con's... a bit large My XI is @ 33.4 in long

FLEXX!

I have a 1995 GMC Suburban and for my system I have a Boss flip out screen head unit, 2 15" L7s, wired to 1 ohm (2000w RMS each) and this God of an amp! It's pushing the full 3200 wired in a bridge series at 2 ohms and my whole truck flexes! I'm not getting its full potential cause I'm using my old systems wiring (6 gauge) lol but soon as I put a 0 gauge on it, with my new custom ported box (being built) it'll definitely slam! I love this amp and highly recommend it!

street beast

Hifonics has always put out the true power rating plus some. The new Colossus is no exception! A beast of an amp at 3200 watts in 2ohm load. Probably a little more depending on your power supply. 2 guage power & ground hookup so you get plenty of juice. Be warned get subs that at least handle 2000 watts or more. So if you want to bump get at least a 400 watt amp, but if you want to pound the sound, the colossus is the s*@$!

colossus is a brute!

The following review is for a previous version (XX-COLOSSUS-disc).

I have recomended this amp to several of my customers who want to be "KINGS OF THE STREETS". This amp although hungry for amperage is a beast, yet still streetable. I have designed systems around this amp powering everything from a quad of orion H2 12's to a pair or JL Audio 18's this amp pounds. bring your big subs to life!

True Power From The God's!

The following review is for a previous version (XX-COLOSSUS-disc).

This is a true "power-house" of an amp! There is a local sound shop that has a display truck with 2 of these installed in the rear, although in reality it only takes one to do that damage. They are running them on a quad battery setup with a whole new power system (Alternator, ect.), but it still dims the lights! When I first heard the amps in use I thought that I was dreaming! I was told before the truck was upgraded with new 1" thick glass, ect. that the amps cracked the rear windshield and caused damage to the front windshield and side windows as well. The price may throw you off, but if you have the cash to spend this is the amp of your dreams!
