The rest of the speakers work just the rear subs are not working. Thanks for any input.
Sounds like to me the sub amps arent getting the "turn on signal".......a low voltage signal from the head unit to the amps.

You need to get a wiring harness diagram for your model / year car and a wiring harness diagram for the head unit. The speaker wires from the head unit should all be in one of the harnesses from it. The power and ground, turn on, etc will be in the other ones.

Post the exact specs for the head unit, type, numbers, etc, pictures of the plugs will be a huge help! Send me a PM and I'll assist as much as possible!!!
