PRETTY GOOD AMP

Bought this cheap ass amp for riding my 12" Kenwood 200watts rms Subwoofer. WOW!!! FOR THE PRICE YOU'LL GET WHAT YOU NEED!!! It is not getting that hot and also it is so small that you can put it in any place you want.

For the price, I think nothing can beat that amp!!!

Good amp for the price

I used this amp to drive the front speakers in my sons camaro. I mounted it where the factory Monsoon amp was located, but I had to first mount it to a piece of plywood. Works well. Good value for the price.
