I would think if there are low level inputs available at the rear then the technic pnp harness would have them and it doesn’t. Or am I missing something? There is one amp for all speakers including the rear deck so where is the low level input coming from?
I just t spliced into the rear deck speaker wiring on my E39. Works great.
