Can you tell me if it is possible to wire up my amp into the oem headunit and if so how do I go about doing it? I have a pair of 10" and an amp from an old car but dont want to lose the oem headunit. I have a 2002 elegance with symphony head unit and cd changer. Cheers:)

Easiest way I would think is a line to RCA convertor.

It can be done -
