Alright guys, I couldn't find it in the search so I have to ask.
Whenever I put amp in the car, I always run new speaker wires from amp to the speakers. This time, I want to run existing wires, but I still need to run additional/new speaker wire from the amp back to the HU harness.
My question is can I run speakers wires and pre-amp RCA wires together in 1 bundle? I know nothing prohibit me from doing that

, but my concern is unnecessary intruduce noise into the system.
I already know that I can't run power and speaker/rca cable together.
