I moded mine

I have one of these amps, Hook up to two juggernaunt 15's and yeah it bangs like crazy. But I found out that you can mod these amps. I moded mine and I 'm running at .5 ohm. And lets say 5000+ watts rms can make you pass out or throw up. These amps are really good, powerfull as h*ll. but when you moded them ohh my god! moded it.

ma audio hk4000

I love this amp, but i have ran into an issue. I have 2 15" MA Audio 4000w subs and the hk4000, 4 1.5 farad caps, 4 batteries all grounded and wired correctly yet my amp keeps cutting out at vol 19.

this pounds!

This amp is the best I've ever heard! It really pounds out some strong bass. Need a lot of power going to it, though. Really is worth the price. Really an incredible amp!

Awesome amp

Everything about this amp is great. RMS watts it puts out, price and the design. I like how it shows how many volts its getting. Its pushing my solo X 18 to like never before. The guy with last review obviously doesn't understand what voltage drops from a non upgraded electrical will do to a power hungry amp.
