Nice Job Dan [thumb] Made it a sticky so that way others with questions can look at this and figure out any questions they may have [thumb]

wow i think that helps, i found the same diagram in my "chiltons repair

manuel."

fantastic...this was a TREMONDOUS help to me tapping the front speakers...

i dont know if this is the right spot to ask this question... i have a 2008 focus. there is a plug, when u fold down the back seats, that has nothing going to it... the plug is red and is on the drivers side. anyone have an idea what this is for?

got any wire colors? i cant find just red connectors lol

me and brad figured out what it was. i was right, it is the stock hookup for the subs... so this is gonna help alot of ppl who want to add aftermarket subs

Are you guys saying that there's speaker wire behind the back seats for directly connecting a subwoofer? Or are they rca cables for the subwoofer signal to the external amp that you have to install?

It's a specialty harness designed to fit the Audiophile Sub setup only. It is not a set of RCA cables, and the wiring is not there on every '08 focus just as not every 00-07 focus came prewired. Some that have the harness but not audiophile setup are just lucky [thumb]

I'd like to correct you on this. In the trunk behind the d-side passenger there is a connector for the sub woofer on all the 08 focuses. The the only reason why we can't tap a woofer set up off of this on non-audiophile systems is because behind the head unit in the dash Ford cut off the harness and there is no 'spot' in the head unit to get a clean sub out. There has been a previous post about this 'issue' where I have posted pictures of the cut harness and lack of connector on the head unit for the appropriate connector if it was there.
