ive got one laying around and i hooked it up to both of my back speakers. both speakers worked but the left rear one was fuzzy so im assuming the amp was damaged or blown or some. still works just fuzzy. im sure it could be fixed? its a classic rockford fosgate punch 45 hd 2 channel amp. from the 90s. anyone wanna buy it? or know how much it would be worth on ebay or somthin?
