Ok, so most of my gear has arrived now and I need to start thinking seriously about exactly where i'm going to put it all / route the wires.

These are my thoughts, please let me know what you think!


Amp. Placement:
I've abandoned the idea of putting the amp. under the passenger seat, it's now going in the boot. The PDX's are pretty small, so i'm thinking of mounting it on the back of the left rear seat. I should be able to mount a piece of MDF behind the rear seat cover to the thin metal of the back seat. The amp. can then mount to the MDF. However, this would mean i'd be screwing holes through the back of the seat cover, which would be nice to avoid...

X-Over Placement:
The x-over's for the SPZ60's are friggin huge, which kinda sucks. I'm thinking they too will need to mount to the back of the rear seat beside the amp.

Amp. Power Wire (4 Gauge):
I'm thinking i'll route the power wire like this: Battery -> fuse -> firewall grommet -> behind passenger side kick panel -> along left-side door sill/panels -> behind far left section of the rear seat -> into the boot.

Amp. Ground Wire (4 Gauge):
I've read, though I haven't pulled the rear seat up to verify, that there is a good ground under the rear seat? I've seen the ground near the fuel pump in the boot, but that really doesn't seem like a good idea. loose ground = (sparks + fuel vapour) = BOOM!

Speaker Wire routes:
The left split pairs (one for woofer in door, other for tweeter in dash) will follow the amp. power cable back to the door and dash. Same route, but opposite side for the right front splits.

Signal Wire (inc. amp remote wire):
In my case, this will be a USB cable (digital audio). I'm running an external USB sound card (from my Infill G4 HU) that will mount close to the amp. with very short RCA cables. This should give me a good SNR. I think the USB cable should follow the same route as the amp. power cable, but on the right side of the car (follow the right front speaker wires).

Your thoughts/advice is greatly appreciated!
