Okay so my car is done being painted and I re install my amps.
I have two amps, one running the speakers and a seperate one running my subwoofer.

The amp that runs the speakers works but the subwoofer is not working.

I am not sure if the two input wires (red and black) are in the proper input/output.

The 12V red wire is correct, the little blue REM wire is in correct and the black ground wire is in correct.

The subwoofer is hooked up to the speaker wire.

What am I missing?? The amp is getting power but the sub is not playing. Have I forgotten something??
