My car is similar to everyone elses however I don't have any RCA cables as I run speaker wire directly to the high level inputs on the amps from my stock head unit. But at any rate I did what the factory did and ran all of the power down the driver's side of the car and the speaker wire down the passenger side. I do have speaker wire that has to cross over to the driver's side door but I have it running from my crossovers under the seats, up the trans tunnel and up to the plastic molding the runs along the underside of the windshield and then down to the doors.
