S13 factory rear amp trigger wire? And OEM audio upgrade options...

[Fred Allen Burge]

Hello,
Is there a wire on the S13 radio plug that triggers the rear amp to come on like aftermarket amps have? I wired in a late model Altima CD player and now the rear amp and speakers wont come on. I did have one wire on the S13 radio plug that I haven't identified yet I'm wondering if that was it, it was light green (no stripe).

Ideally I'd like to replace the rear amp w/something a little more powerful but still use all the factory wires to power and trigger it. I'm considering one out of a late model Sentra that had the 300w Rockford Fosgate sub woofer and amp system.

thanks,
Fred

Light green/red, but it triggers all three amplifiers, the rear one and each front one in the door. If your fronts are working there's a problem, either you don't have an amplified system or the rear speakers are blown. Or, the rear amp is missing. On fastback models it's mounted below/beside the driver rear speaker.

Thanks, got it sorted out, they all come on now.
