91 Civic Speaker Wiring In doors need HELP!!!

How would i got about putting new wire throught to the doors i cant get the wiring harness out of the door and i dunno where to feed the wiring through. This is on a 91civic Sedan

From my car audio experience, I've found it best to use the factory wiring when it comes to the doors. Why? It's a big hassle to remove the rubber grommett and rewire everything. You reeally won't see a real difference in sound quality of that (very short) run of factory wire. You can run your amplifier to the front speaker outputs on the dash wire harness (the one you used to connect an aftermarket radio with). By the way, if you remove the factory 5 1/4" speaker baffles, you can run a 6 1/2 woofer in those doors. be careful of the mounting depth. If I'm right, you can only get by with a 6 1/2 that's 2 inches deep. Troy
