RCA Subwoofer cable with AMP remote turn on

[SeaPro]

I've got a set of RCA cables with a third, single wire.



This is my first time wiring a stereo, and am wondering if anyone can tell me the purpose for this third wire? Is it in fact an Amp remote turn on? My kit came with another, similar gauge wire that I assumed was the amp turn on, but I'm feeling kind of inclined to use this for my remote turn on, because it would be a lot more convenient.

I've read that it's not a good idea to run the remote turn on too close to the RCA cables, is there any truth to this?



Thank you!

I've wired up many sound systems and have never seen a turn on lead bunched with the RCA. If you have a turn on lead in your kit, I wouldn't even wire up that wire. You will get interference.

In some vehicles it is used as a ground for the RCAs. to help with noise.
