What is the remote wire for.

The remote wire coming off my head unit. I plan on running that to a bus bar so that I can turn my amps on and avoid the pop. Can I also use the remote wire for the fans or will the fans need there own dedicated power source?

I purchased a 30 amp relay, 100 ft of 18 AWG and I am about to go pick up a buss bar. Can I power the fans off that remote wire? or should I use relay for all of the things or what?

So then the remote wire is enough power to turn the fans on and run them so that the fans only run when the trucks electrical is on? I was confused about running them from the rear battery because then the fans would always be on. This all sounds correct right?

the remote wire should be run to a relay that turns on the fans....don't run the fans directly off the remote wire

For my relay, my ositive wire from my battery does it go to terminal 30, remote turn on to 86, and the power to the fans comes from either 87 or 85 which one and is this correct for a SPDT 30 amp relay.
