I'm using the Crutchfield 7 speaker harness and the subwoofer is not working. Solid blue connected to what? There's no wire to connect it to coming from the stereo. Can it be spliced together with the incoming Acc. power or is it looking for a PCI bus signal?
I do see in the schematics there is supposed to be a 12v source coming from the radio (pin 13) going to the subwoofer. My harness also has a blue wire at pin 13. I guess it won't matter that the sub is powered on whenever the key is on, even if the radio is off.
Life is short. Play hard.
