Itd be easier to just re-run your RCAs. Dont be lazy, it'll just make things more difficult to run your power wire from your battery to the driver side, through the firewall, etc etc.
Run the remote wire with the RCAs on the driver side, just for uniformity. And speaker wires, should be able to run them as is, I mean, you can't really avoid running wire past the power wire for the doors, but if you amp is in the back, try and run them through the center console rather than along the sills.
