Best Wiring Routes to the Trunk

[robinpc]

I'm installing a CarPC in a 2007 Mazda 3 sedan, and would like to put it in the trunk instead of under a seat or in Glove C. Which means routing at least two power cables and an audio cable (I use bluetooth for control, so no video, but others might want to).

Looked around, but haven't seen any descriptions of best ways to neatly route cables from the trunk to the headunit location. I could improvise, but I'm sure this has been done many times by many people, and better than I could figure out.

So ... any suggestions for running about 1/2" in diameter of cables from the very front to the very rear in an invisible way?

You can fit most wires under the running boards. They pop right off and there is a channel with factory wiring already there. If you need more space you are going to have to remove the seats and run stuff under the carpet.

Here's a photo from my Protege5 install. I fit a trio of speaker wire, a changer cable, an optical cable, and a remote turn on wire all under the stock running boards.
