My stock radio works well and was thinking of adding the CD changer, amp and subwoofer. The radio has the CD button and the blue CD changer cable was run from the back of the head unit to the back of the car. Question is there is no plug for the amp other than what looks like an old style plug like the ones used for a computer monitor or a printer. Does anyone know what factory amp was used and what this dangling plug was supposed to be used for? All the factory amps I see on ebay have a standard plug none like the one that's hanging loose from the top of my gas tank? Thanks
