A great amp.

I bought this amp to power my 4 MB Quart 6x9's and they sound great. It has taken my audio system to the next level. You will not be disappointed in this amp. It is built like a tank.

Gamble

I took a gamble when i first bought my system. I wasn't sure what to get or anything. I thought MB Quart was a good amp, but well three months in, past the winter and spring season, it was still good. It finally broke a week ago. I was quite angry and thought it was the distro block i had but i was sadly misinformed. The installer said (after doing a few things) that it was the MB Quart power supply and well i called Sonic about it and now I have to wait for a RMA number then pay to send it back and pay to get it back to me.

HAVE HAD THIS AMP IN MY 1981 CORVETTE 7 yrs NOW.

I love a lot of bass & I really don't care about the highs. I have two 10in Kicker speakers in a box that takes up the entire area behind my seats. Infinity speakers in doors, Infinity tweeters in the dash & Blaupunkt stereo. My friend suggested this brand Amp. He installed everything shortly after I bought the car 7 years ago. I've never had anything go wrong with the entire system. (No subwoofer).
I love it, It puts out some serious, deep bass with no distortion and wants more!.
