MB Quart NA180.2

Good small amp. I am powering a 12" sub with it bridged. It has good power but I would limit it to a 10" Sub. If you are going 12" or higher I would get a larger amp.

MB Quality

Bought to power a 10 MB Quart marine sub in sealed box. I bridged the amp to meet the 4 ohm rating for the sub...amp has more than enough to power this sub on our boat. Good looking amp and the "MB Quart" logo glows red.

Bid Bang for the money.

This is a great amp for my 8" Pioneers in the boat. My Sonic sales rep really set me up and without spending more than necessary. These guys know their stuff and this MB Quart amp is a great value.
