It's only 4 from headunit to amp. Also rear doors are connected to d-pillars.
I guess you need the luxury amp and you get separate D pillars and center speaker ('07 diagrams here)
Where is the amp mounted?

Where the sub is, is it separate from the sub?
yes the sub is in the front part, amp is in the back part, when you lift the cup holder out the harness is right there near the bottom of the storage box
this is mine where I cut the anc mic feed

Sorry, just seeing this.

The rear control being unplugged is why you have no rear speakers functioning.

The tweeters in the A-pillars are wired in parallel to the front door speakers, same goes for rear door and D-pillar speakers.

My guess is your driver's door speaker took a crap and needs to be replaced.

Filled the washer fluid and changed out a couple wire stand offs that were broken, salvaged a few decent ones from the junkyard, then replaced a couple sections of wire loom purchased a big box full of loom and shrink wrap for like $30-40 off of eBay a while back, these clips you can't get separate you have to buy a wire harness to get them

I have looked at every clip they carry before, they don't have the one that is a female mount and they don't have the S shaped clip to hold the coil pack harness to the bracket, I had one of those that broke also, I finally found one at the junkyard that worked.
almost all of my clips were brittle and crumbled when touched. I have managed to replace all the bad ones now I think. I just have keep my eyes open for them.
I still need the one that clips the oil cooler lines to the fan shroud, I just have it zip tied for now.
broken clips and leaks are a pet peeve of mine
