Managed to do about 80% of my wiring today. I had many mistakes along the way that slowed down the process.
1) I wired all 20 of my door speakers incorrectly, so instead of 4 ohm loads on the front doors and 2.67 on the rear, I was reading like 0.7 on the DMM. Had to remove about half the speakers to fix it.
2) Pioneer Head Units have a blue striped wire called a "remote relay switch", which I read could be used as a 12v switchable to run to amps, but for some reason mine didn't work. So I had already put the dash back together and had to pull it apart.
So far I just did one run of 2/0 under the vehicle and popped up behind the 2nd row.
I'll probably need a 2nd run down the line, but I REALLY REALLY wanted to get my door speakers on some real power XD
Here's some pictures of my wiring mess
I had to run a total of 8 sets of wires:
1) Voltmeter (3 wires, one to 12v switchable, then a positive and negative to my rear amp)
2) Backup camera (4 wires, power, ground, 12v switchable, and one wire to the head unit itself)
3) Positive / Negative wire for 20 speakers @ 1.14 ohm load
4) Positive / Negative wires for left pillar @ 2 ohms
5) Positive / Negative wires for right pillar @ 2 ohms
6) Highs RCA
7) Mids RCA
8) USB wire from head unit to under the glovebox
I took all of them through the trim pieces on the right side of the vehicle, like I did in the Tahoe. Didn't take pictures though.
Someday I'll have to go back in and add the 3rd RCA for subwoofer.
And then right as it was getting dark I had my temporary test bench setup!
Always keep a fire extinguisher in these cars, especially when running Brazilian amps, since I've personally had 3 of them set on fire during use.
Got to play like 30 seconds of one song and man these doors are loud.
Tomorrow I'll run the wires for my A-Pillars, make some mounts for the amps, clean up my wire mess, setup my backup camera, etc.
