Great Amp

I have had this amp for quite some time now and have not experienced any problems. I just recently upgraded from a 4awg wiring kit to a 1/0awg. If you plan to run this amp like me at .5 ohms then I definitely recommend 1/0awg. This amp is powering 2 12" kicker cvx's and they slam. I actually have to keep the boost and gain relatively low because I am afraid of blowing the subs. The price seems a lot higher then what I remember paying but if you want a competition grade amp then this is a good buy. Also the amp looks great, this is definitely one to mount in the open to show off.

this amp is hard core

i have 2 MA Audio MA1200XL 12" 600watt dual 4 ohm subs hooked up to this amp running at 1 ohm it bangs hard hard... hasn't overheated, display on the top is real nice for working out electrical problems and verifying voltage and temperature... only bad thing to say about this amp is on the top it has hundreds of tiny holes so u can see thru to the circuit board which means it has no water resistance whatsoever, afraid to even consider opening my trunk while its raining... but thats probably why it stays so cool... great amp i would recommend it to anyone who's trunk doesn't leak!

Great Buy!

I have owned this amp for about 7 months and I have to say, it is a monster. I have it pushing 2 15" MA Audio 1500XL's with ease. I have also had this amp pushing 2 MTX 15's as well with no problem. Never had it overheat, and its pretty heavy, built dependable. Would recommend to anyone looking for a great amp at a great price.

nice amp

A lil power hungry but gets the job done. i haven't run it under 1 ohm yet but pushing a true 900-1000wrms at 1 ohm for this price is amazing.

had it on 2 kicker compVR 15 dvc4 and it slammed in my Cherokee.

Awesome amp!

I have this amp running 2 MA 12" HK's at .5 ohm. It is super stable, clean and has never overheated, even in 118 degree weather. I would definitely recommend this unit for anyone with big speakers.
