awesome buy for the money

This amp is unbeatable for the money, easy to install, and will do everything it's supposed to. I am very glad I purchased this amp. I don't make alot of money, and I did a ton of research on the web. I was hesitant at first, but now I'm satisfied with my choice. It's not a window rattler, been there done that, but the SQ is what I was trying for, this time. So if you are looking for good bottom fill, I do recommend this amp. I have it powering a 10" Poweracoustik FBX, like I said, I'm pleased with the SQ.

Awesome Amp

overall this is the best amp i have ever owned, it is the easiest thing to use, its durability is awesome, i once dropped it out of my truck, from 4 feet up on accident, and it had no damage whatsoever. It is the best amp for the price.
