Review: ... i finally settled for MB quart and I'm very pleased to have made this decision - after reading several reviews on tons of amps i finally settled for MB quart and I'm very pleased to have made this decision. I have this amp firing sundown E12D4 (rated 400wrms but can take more than that) wired at 2 ohms and it's bringing the best out in my sub. With head unit's (jvc kw v20bt) sub power all the way up, I only have to crank the bass nob up 1/4 way and the sub vibrates everything in the car. I will be sticking with MB quart amps in future as well and I highly recommend it to anyone who wants a budget amp that kicks some serious ass!
Review: Great amp - Perfect match for the 12" MB Quart sub I purchased to go along with it. The remote bass knob that comes with it is very responsive and has a very wide range to it. I frenched the knob into the dash so it looks factory and functions perfectly. Like anything with car audio components they are only as good as the wiring that you use to hook them up, so don't skimp on the wiring.

Great Instructions, worked as expected, very clear sound, no over heating, good price for a quality product. Oh, it fit under the rear seat of my 1999 Jeep Cherokee sport. Will add photos if I can later
