How far does your power wire need to be from your head unit?

[joshme17 10+ year member]

I'm trying to route a power cable for my amp in my trunk to my battery in my 1994 Oldsmobile Cutlass Supreme.

I want to avoid having to drill a hole in the firewall but I can if needed.

I found a place towards the center of the car where some cables and electrical wires a ran that I think I could get the power wire through. But the wire would run pretty close to where the head unit would be.

How far does the power wire need to be from all this? Will it cause problems if its about 6 inches from the head?

Please don't say this is a stupid question, this my first install and I don't want to mess anything up.

Im telling you, drilling a hole is easiest and most convenient, just place a rubber grommet in the hole, and itll be like it was factory.

I dont think it will bother anything and its not really a stupid question, a big power wire like that can cause interference but probably none that youll notice.

Easier than using an existing hole? lulz

OP, no one can say for sure if it will have any ill effects, I would have to say no, it will be fine but the only way to be 100% sure is to try it and see.

Thanks for the help. I guess I'll give it a go and see what happens. If I get noise, I'll probably just go ahead and drill through the firewall.

Lol, well on my car, it was easier. I just think it nice to drill your own hole, and that way when you upgrade, you can switch out bigger wires to it.

No matter what the car, using an existing hole > drilling a new one
