I have a gently used Memphis Audio MCD500 500 watt amp and 1 Memphis Audio MS104 sub woofer
They were working perfect when i took them out of the car. (lease was up)
The amp is missing the little covers on the side. Other than that they are in great shape. A few scratches from storage but nothing that my camera would pic up

I live in Bergen county and work in Newark.
