I tried to go around the amp using the factory wiring, but found that it appears to have been cut somewhere. None of the connectors on either side of the amp have continuity with the pins on the speaker's connector. I might drill a hole in the door and body and run a wire alongside the wire tube (& black box). Unfortunatly, much of the factory wiring is hacked off in my sho from a previous owner. I got it with a Pioneer head unit connected to the rear speakers, with the amp bipassed. I've now got the passenger front speaker hooked up, but I didn't have to go through a black box! wink
