Here is a write up I did for a rear 12V power outlet I just installed in the subwoofer box. I used a flush mount outlet from radio shack (about $10) and some 8ga wire. I used 8 because I plan on running the wire to a rear fuse box and then running the outlet and other accesories off of the fuse box.

Here are some pics:



First I removed the sub box from the Jeep and then removed the speaker



I then drilled a 1" hole in the box for the outlet and drilled a smaller hole in the back of the sub box to route the wires through







Since I had the box out and it was scuffed up a bit, I gave it a light sanding and bedlined it



I then ran the 8 ga wire down the passenger side of the Jeep in the existing wire loom for all the stock wires. Once up front I ran it through the passenger side hole in the firewall to the battery

 

Nice job--- been thinking about the same location.

 

Very nice mod. On my future list.

 

Thanks, My next is going to be installing a 120v outlet, im just unsure of the location...maybe the other side of the sub box? or the center console...

 

Great job looks clean

 

Rear fuse box?? Where is that?

 

Looks stock, good work.

 

He is going to be adding one at a later date to the rear.

 

Like that idea, thanks

 

A fuse, properly sized for the wire gage and its length, should be installed at the battery end of the wire.
Fuses are installed to protect the wire run, rather than the load.
