Amazing build quality
This amp has excellent sound quality, but most importantly it fits under almost any seat as its the thinnest 4 channel amp of any i've found.

very satified
I wanted a clean amp for less money, and i got exaclty that. very nice amp, clean sound, great power for my infinity kappa's. I was leading towards infinity or jbl but, i am glad i did my research and MB Quart came up on top. Very impressed with the specs, Good quality all around. JBL have some high frequency response but, what can you really hear beyond 20,000 anyway. Save your money, you can't go wrong with MB Quart amps. Get yours from sonic before they realize they are selling too low of a price...

Excellent amp
An independent test verified that these amplifiers are underrated by about 30watts (4ohms). The amount of power is amazing given the size of this amplifier. I use this amplifier to power a set of Hybrid Audio Imagines running active. The sound improved considerably after switching to MB Quart from my older Jensen amplifier. The only possibly concern is cooling. This is a compact relatively high power Class A/B amplifier, so it can get hot. The other time I was on a road trim and put my bags all around the amplifier. It shut down after 15 minutes. This is not a big problem. It needs good air circulation. Just pointing out. Another minor issue is that the power connector will not accept wire bigger than 8gauge.
