Basically I'll say what I was planning and say where I need help. I am open to new ideas.
So what I was planning was:
Run a 0AWG power cable from battery to distribution box either under passenger seat or more likely under the back seats.
Run power cable from box to sub.
Earth will either be in the boot or I've heard the passenger seatbelt bolt is a good place (what do you think?)
(For now) run Hi-Low converter from back speakers to sub amp.
Remote from stereo down the drivers side (if anyone has a link for how to wire this would great)
Near Future plans:
Wire a small computer under the passenger seat.
VGA cable and USB to head unit.
Audio cable to sub in boot and amp under drivers seat.
USB to hub in glove box.
Wire a 4 channel amp under the drivers seat.
All speaker cables from HU down drivers side to Amp along with remote wire.
So, what do you guys think?
I have found a guide for power cable to boot. But nothing for wiring down the drivers side. Has anyone got a link for this?
