running wiring in my truck?

[standard85 10+ year member]

I heard when running wires in any vehicle to run the RCA wires on one side and then run the 12V power cable, remote wire and speaker wire on the other side. Can I run the one speaker wire for a component set with the RCA's or will that create unwanted noise. And If I run the ground cable next to the 4g power will that also create noise. thanks.

12v power and remote on one side, rcas and speaker wires on the other.

power and ground wires next too eachother will not make any noise lol. only when an rca cable is by a power line will it introduce engine noise.

also pioneer headunits have a pico fuse that blows, and it grounds the rcas, if theyre not grounded, the hu or rcas will pick up noise no matter what.
