Hi,
To my knowledge there aren't any door amps in a Classic, just 2 mounted on top of the sub, one which does 4 Channels, 2 Front, 2 Rear and a small Subwoofer Amp which is also on top of the sub. This lot is all fed from the front via screened cable to the rear.
You basically need a Head Unit with 3 Pre Outs on it, connect these up to the corresponding cables on the old DIN plug and it will work.
I bought a 10 Pin DIN connector to preserve my wiring and then terminated it with RCA's and plugged it into the back of the Head Unit.
Good Luck
