Customer Reviews

3 Star Rating Aldon From St. Pete, FL

This amp gets a mixed review from me. It sounds great and was a huge upgrade from the factory. My problem with it was chanels 3 and 4. They did not work properly(they sounded awful and terribly distorted, which I looked into these amps and there had been a number of cases where this problem had occured). I bought this amp to run 2 pairs of ppi components(also purchased from ocs), unfortunatley I have to run them all on the 2 front chanels(which still sounds great but I would like to run at 4 ohms for a cleaner/cooler performance). I purchased this setup a few months ago and just now decided to get it installed. since one month has passed my warranty is no longer through OCS, but maxxsonics. I will be contacting them tomorrow and see what they say on the issue. I will not buy MB quart again(unless its their really old, original stuff, they were great). My next setup I will be going back to Boston Acoustics. I am very pleased with their products in my other car
