Hi, i have the the bosch double din sympathy headunit in my 2001 s3. I need more bass and have a sub and amp sitting in my garage, was gonna get a sub from andymac but I am skint at the mo so would like to try and fit my old sub to the car, i know the sub is powered by its own amp and a seperate amp powers the speakers.
So how do i get the sub working, im not sure if the back of the headunit will take rca cables. Dont wanna use original wiring from the bosch sub maybe theres an adaptor i need? any help would be much appreciated.
