which wires to seperate to limit noise?

[1two3]

I know there's a little ongoing debate weather or not running rca wires and power wires together causes a transfer of noise. That's not what I'm asking here. Assuming its true, which wires should u avaid running together? My cables are going to be as follows:

Power and negative front to back (2/0)

Signal wire for 2 amps

2 sets of RCA's

Speaker wires from back to front (on either side)

and probably a few accessories like fans for amp cooling and interior lights, maybe a car alarm sometime in the future

Keep power separate from rca's and your rca's separate from your speaker wires. Remote wires usually don't cause to much trouble that I know of. If I'm wrong guys let me know.

RCAs should be clear of all power wires. If you must cross over it, do it at 90 degree angles.

It's a good idea to keep power and line level (RCA) cables apart. But more importantly, make sure all grounds are good... especially the head unit. Head unit ground is the reference ground for your line level signal and if it's not solid, you'll have noise even if you run your power wires in someone else's car. ;-)

Some say run them all together because it doesn't matter, others say separate all of them because it does.

I choose to run them all separate just because i can, fuck it

I think these days,. thats a wives tale.

Maybe 20 years ago, that would be something to take into account. These days, i dont think it plays much here anymore.

How do you make sure the ground is good at the head unit?..... Since everything is still apart in my car now would be a good time to do it

You could check it with a meter to find out how much resistance there is between the ground and your engine block or frame. Or, you could just make sure that all your factory grounds are clean and solid.

So follow the negative wire from the head unit plug all the way to the frame and check that way or should there be an additional ground wire screwed into the head unit somewhere?
