Finishing up my audio install this weekend and i want to make sure i dont have a chance of engine noise. Just have to run 25 feet of speaker wire over to my amp and run two sets of rca's 18ft each. Rca's with oviously be very far away from my power and ground wire's. Where do you suggest i run my speaker wire? Zip tied up with the rca's or zip tied with my power and ground? Or away from them both?
