I will be installing a head unit, multi changer and amp and box in my 306 next week hopefully.

Now do all three types of cable need to be run in different places to avoid interferance.

Ie, power one side, multichanger cable middle, RC(or whatever they are called) ont he other side?

Or does it not really matter?

Hey Cookie

If possible the power cable and speaker cables should be kept separate for best sound.
The RCA's should be shielded so they "shouldnt" be a problem.

And dont worry about the CD's jumping. There will be a filter that will prevent this from happening. I had no probs with mine and it was sat behind my old set of subs.

I kept my power cable under the left side as its closest to the firewall... run the power cable straight on the left, then the other ones you can put on the right side of the car,

or take the middle bits off and pass it under there, what i would recommend... near the gear and handbrake etc....

u can put the 2 cables through the centre, on different ends..

Thanks guys :)
