Great AMP

Ive got 4 5x7 door speakers and 2 6x9s running off this thing they all sound great pumps more than enough power to all of them with the gain at half. im thinking of turning it down alittle. All in all cant beat the amp for the price. I love MA Audio Amps.

Ma audio amp

This is the second ma audio amp that i have installed into my vehical and i am impressed with how much of a beating these amps will take. They are not very well known like kicker or Jl but i would rather run these amps, because i have ran those amps before. However i perfer Ma now because to me they run cooler and more efficent than ones i have ran in the past. Overall i would suggest people try them out i have and i wrote this to clarify how much i like them.
