How do you run the wires for a amp/sub?

[Ghostbuster]

I ordered a sub, amp, and box.

I'm gonna buy an amp wiring kit local.

How do I run the wires from the battery into the truck.. all the way to the back where the sub and amp will be?

Eta: non monsoon

Check the back left panel. Factory wire harness may already have what you need.

On the right side there should be a little round rubber thing poke a hole in that with a knives and run your wire through

When you are wiring, you should run a heavy gauge wire from the power source (battery?) to the amp. You want to avoid having that power line run alongside speaker or signal wires, like a CB antenna, as it may cause interference on those signal wires. If you do have to cross signal wires, do so at 90 degrees to minimize interference? What size wire? http://www.gtsparkplugs.com/WireSizeCalc.html

Your ground wire should be close to the amp itself and should also be a heavy gauge wire. There are existing ground points back by where the Monsoon amp would be, underneath the gray plastic on the side in the cargo area.

As for running the power wire, it's through the firewall as already pointed out. Remove the plastic door sills by pulling up (they snap in place) and run the wire under the carpet or along the sills. Really you just figure out ways to tuck it out of view as you get to the back seat, etc.

Be sure to seal the hole in the firewall with RTV silicone when you are done to avoid water intrusion. If you drill a new hole, be sure to use a grommet to protect the edges of the wire, and then silicone to seal it.

For example, this is how I ran my CB wires. While you see a ground wire in this pic I've since rewired it and only the power wire goes through the firewall. I used a ground closer to the CB itself.

Thanks for the info guys. I will start wiring it up tomorrow. The sub won't be here until Monday.

I like to go the extra steps, and add not only a fuse holder with a fuse at the battery connection location for the amp power wire, but also loom the wire at any point that it is exposed, both on the outside and inside the vehicle. It not only looks better, but it protects it as well.

Yeah that would be insane.

Great points, especially the fuse. My pic was one of my earlier wiring attempts (definitely amateurish) and now my wiring is better protected. It's loomed where exposed but when under carpets, etc. I try and zip it to existing harnesses or hard points. An unsecured wire will move around, even under carpets, and may fray. This will create shorts and/or ground issues down the road that are difficult to locate.

Be careful of pinch points too, like when running the wire under the plastic in the cargo area. Something minor now could turn into a major headache later with a damaged wire. If necessary, notch the plastic or pinch point in an inconspicuous spot and run the wire through there. Take your time on wiring as the extra few minutes on this job will save hours of frustration down the road.
