Best wire routing location?

[ctrout]

I need to bring a ton of wire from the trunk, through the rear seat, to the area under the dash. I have an 8 gauge power wire, two pairs of 14 gauge speaker wires, a remote power wire, two RJ45 type cables, and two additional cables that are about the size of 10 gauge speaker wire. Where would be the best place to come bring the wires through the back seat, and where will there be room to invisibly route the wire underneath the dash?

Also, which wire at the factory amp runs the remote power?

Can you provide some info about your car? What year is it? Do you have navigation and/or dsp?

Oh yeah, I forgot that part. It's a 2001 530i 5 speed manual. No nav, no DSP, no phone, just the business CD and MID.

Here's how I did it.
Take out the side trunk liner so you can get to the big rubber grommet the battery cables go thru.
Remove both parts of the rear seat.
Take the door sill off on the pass side, rear and front.
Take the pass side kick panel off.

All the cables go thru a trough that goes all the way to the front of the car and exits at the kick panel.
Snake your cable thru the trough. I've added more since I took these pics.

The small white wire on pin 2 is the turn on signal.

That's exactly what I was thinking, but I didn't know that grommet was there. Thanks! That's exactly what I needed. I spent some time today tapping all of my speaker outputs at the amp and pulled the power from the three open fuses in the voltage regulator fuse panel in the trunk. Now I just need to figure out which wire powers the amp remote power, then pull the wires and start hooking everything up. I'll probably do that on Saturday. I'll be putting the 10" Memphis Nanobox in the passenger footwell. This will provide some nice, powerful mid/low range sound. The 12" sealed sub and Alpine 500w monoblock will fill the low, sub-bass.

Thanks for the picture showing the white remote wire too. That'll make it super easy to find when I get back to the project in a couple days.

If you need to get any wires from the pass side over to the drivers side remove the upper panels on the side of the tranny hump (1 Phillips screw up by the firewall), slide the panel back to remove.
Remove the foam under the the HVAC unit to snake the wires over to the drivers side.
