Ok, I have the amp, subs, head unit , door speakers, and all the necessary wiring needed to have a decent audio setup. However, can someone help me out with the actual wire routing? I can install the head unit and the door speakers with no problem, but I need some advice with drilling a hole through the firewall to supply a route for the power wire to go from the battery to the amp, and I also need some help with routing the ground wire of the amp and whatever excess speaker wire I might have. I assume I'm gonna have to take out the backseat, and if so, is there a certain way to do this? Screws and bolts in certain locations? I'll appreciate any help given. Thanks

 

The best way to run your power wire is going to be through an exisiting rubber gromet. Just open up the gromet, and stick your power wire through, and proceed to run it. Be sure to keep in mind that you need to run your power wire, and RCA's on seperate sides of the car to avoid noise interferance. As far as grounding the amp goes, you can ground it to the bolts in the back seat, or just find a place in the trunk, sand of the paint (so you get good ground connectivity) and secure it with self tapping metal screws. I'd give you exact locations, but I don't own a teg. Good luck man! Out of curiousity, what items are you installing?
