We got the amp and everything hooked up professionally and then got a Sub from a friend. It has two inputs, two black & red cable input, but only one of the sets looks like it's been used. what is the other one for? and we were also wondering why the stereo guy gave us extra cable if there's already a cable coming off of our amp?
Car Stereo subwoofer installation help?
