the car (and the deck I suppose) are from 1988. Those 1988 e30 cars ALL had common ground decks.

Even if his amp (and there have been different ones in different sound setups) should be "normal" instead of common ground, the deck might use common ground and thus you have an amp that is only able to receive signal from a common ground deck.

The same with the DIN connector; this may or may not have been standard in all of the different sound setups in different systems.

Instead of going through the money and trouble of purchasing or making a connector which you can take to the amps DIN connector, with the same time, effort, money and parts removed you could just run new hifi speaker wiring and forget about the amp which, like you mentioned, is only 4x25 which is LESS power (read:bass) than most modern decks are capable of. Those MOSFET amped decks are really stunning, I saw no reason whatsoever to run the speakers via amps with 50W per channel produced by the deck.

About the RCA: I've come to understand that the original amps never had RCA connectors, instead there were inputs via normal speaker wiring or a DIN connector.

You cannot use RCA (low level input) with these (high level inputs) since the signal is way too weak.

Remove the original deck and see for yourself how many speaker wires there leving from the deck.
