I have an MB Quart DSC 2150 amp and an MB Quart 200.92 8" subwoofer for sale. The amp is a 600 watt two channel and is bridgable. The 8' is an actual MB Quart sub, it is not a Hifonics made sub. It is one of the original MB Quart builds, never been installed, still in original box. I am asking 200 plus shipping.
