The Nakamichi amp in my '92 SC400 was damaged from water, so I bought a new 4-channel amp to replace it. I used the wiring diagram to hook the speakers up to the amp as follows:
Channel 1:
FL+ - Pink
FL- - Violet
Channel 2:
FR+ - Light Green
FR- - Blue
Channel 3:
RL+ - Black
RL- - Yellow
Channel 4:
RR+ - Red
RR- - White
Power:
Blue/Yellow
Remote:
Gray
Ground:
Brown
The amp powers up just fine, I've got 12V between Power & Ground all the time and 12V between Remote & Ground when the key is at ACC or ON. I connected my phone to the amp and tested each channel to ensure the speakers are connected properly. I get audio from the driver door, both the main speaker and the tweeter. I get audio from the tweeter in the passenger side door, but not the main speaker. I don't get any audio from the rear speakers.

Does anyone know what I'm doing wrong here?
Thanks!
