For those who have done it, which routes did you find best??? 1)Im looking at routing the power cable thru the ECU into the cabin, is there any other better ways??? 2)Looking at the speaker and RCA routes, there is original wiring down both sides of the car, better to take these down the middle of car or do you not pick up anything from the original wiring down the sides? Ideally i was wanting to run speaker/RCA down one side and the power supply/remote down the opposite to limit removing more trim and possibly carpet, has everybody else went this route? If so, which side with what? Cheers.
