Alternator noise comes through (+) wires, right. When running power, remote and signal wires, should I keep power wires separate from signal(RCA's)? I just decided to add a couple of amps to my factory speaker locations, and wanted to make it right. Also, is there any detectable noise from running different signal RCA's together? Thanks for any help.

""When running power, remote and signal wires, should I keep power wires separate from signal(RCA's)?"" YES

""is there any detectable noise from running different signal RCA's together? "" Not that I'm aware of.

Also keep your ground wires from your amps as short as possible (less than 1ft).

If you have no choice but to run a signal wire (RCA or speaker) over a power wire, make them intersect at a right angle to minimize noise.

Also, use the best quality shielded RCA's you can afford to keep the noise out. This is the most cost-effective purchase you can make towards reducing inductive noise.
