I need help running the power wires and the RCA wires through my Buick. I've done other cars but in my Buick everything seems sealed off really well. First where would be the best location to run the power wire through the firewall. Second how would I run the RCA and remote wire behind the head unit. Behind the head unit seems sealed off.

It's best to run the power down the same side as the battery. Just drill a hole and put a grommet in.

If it's an aftermarket HU, slide it out and use a retractable claw or fish tape the run the leads up to it.
