can i run my speaker wire and rca cables in the same door jam or do i need to run them seperate.

power wire is seperate from rcas but does speaker wire matter or not

another questions trying to wire up my apline 6.5 coaxils how do i know which one is the postive and which one is negative or does it matter

it doesn't matter, you get buzzing from bad grounds.

typically the ground is the - and the positive is obviously a +

and when the connectors are directly into the speaker the larger tab is the + and the smaller is -

thanks going back to work/
