Today I cleaned out the old aftermarket amp wiring that was found under the big floor bin in the cargo area. I also pulled the 4ga power wire that was run up the driver side to power the amp.
With that out of the way, I ran my 12/3 power wire to the rear cargo area. The outer insulation jacket was too big to fit through the firewall, so I removed it as well as the internal fiber wire spacers.
Once the 3 new wires were ran through the firewall, I sleeved them with some split loom.
I decided to open up an existing hole in the inner fender just large enough to run the split loom through it rather than sending the wires around the end of it. I sprayed the bare metal with some grey primer sealer to keep it from rusting.
I'm just going to store the battery end of the wires down beside the battery until I can pick up a couple junction blocks. One for battery power and one for keyed power.
Then it was just a matter of running the new wire out back, following the factory wiring. I zip-tied the new wires to the factory wires as I went to keep everything out of the way of the panels and carpet.
And this is where the new wire is going to lay while I wait for a dual input fuse block. One input will be battery and the other input will be keyed. Each side of the fuse block will have 6 of their own fused circuits. In this pic you can see the old ground wire for the amp, and the 3 tec screws holding it to the floor.
