Crunching the #'s on audio system wiring and have a few questions from those that have done it before:

Power wire from battery to amps behind rear seat (driver side) questions:
1. Approx how many feet is this wire run (through passenger side firewall, down passenger side, behind rear seats to driver side)?
2. What is max wire gauge you can use through this route? 2awg or 1/0? Will also need to fit GJ wire harness.

Speaker wire questions:
1. On the B&O system, are there dedicated tweeter wire runs?
2. And if so, what wire gauge? Will be feeding them ~80W RMS, so want to know if I should pull wire for those as well.

Thanks in advance!

1. Figure 20 feet is more than enough. This will be enough to easily get where you need it and have a tad left over just in case something goes wrong.
2. You can fit whatever gauge you want if you install this correctly by drilling and using correct sized grommets. If going through the factory grommets is the only option then I'd say 4-gauge will work but anything larger will be tough and will risk cutting into the factory wiring.

Second part:
1. Yes
2. 18 gauge will work fine.

I was under the impression the tweeters r run off the head unit?

Correct, the A-Pillar tweeters are powered directly by the Audio Control Module (ACM), not by the Audio DSP Module (Amplifier).

The factory tweeters use 20 gauge wire.

Thanks for the feedback, 4awg is probably too small at that distance - I'll have to look into this some more.

1/0 fits through the factory boot/grommet no problem. Just make sure you have Vaseline. It makes the job incredibly easy.
