Does anyone have a schematic for the sound system wiring for a stock Becker 90' 560SEL???? system looks like 6 speakers (2 front, 2 door and 2 rear) fader and amps behind the rear seat. I'm tryin to install a new 4 chan head unit and have seen lots of confusing post. I've defined the fader input and outputs they have a common ground for each speaker channel.
The rear pass speaker has no sound from the Becker unit, all the of the other speakers work. Back seat is out, fader console apart and Becker removed, just need to know where to get all of the speaker + & - connections.
Thanks for the help, I looked through so many threads that I figured it was time to ask directly.
Regards,
Bob
