i took my pass side wind shield cowl off, and on the left side under the windshield i drilled a hole, and fed the amp power wire through the hole, it came out at the pass side floor, i tucked it behind the rug and ran it along the side to the trunk. you can take some vac line, cut it then put it over the amp line to protect it from the hole you drilled.

only part that sucks is you ran it already, you cant feed it up, you have to feed it from the engine bay. so to do it this way you need to take the amp wire back out, and start over. this way you can have a in line fuse under the hood too close to the battery.

my amp just needed a 12 v remote wire, i added a add a fuse to the wiper fuse, ran the remote wire from there, it only works if the key is to run.
