Need help replacing headunit I have a 1996 318ti with the standard OEM/Alpine Tape HU, 200w trunk amp, & 10 speakers. I just want to change the HU & keep everything else stock. I know the wire color codes, will use BMW wire harness & antenna adapter from Crutchfield. I'm looking at the Blaupunkt Brisbane SD48, which has the choice of pre-amp outputs or standard speaker level outputs. Anyone know which are the correct ones to use with the stock amp? TIA |
