Audio Wire Cluster?

Hey does anyone know where the audio wires run to the rear speakers?
I'm going to splice the wires to hook up a line output converter but i don't want to do it behind the factory head unit because there isn't enough room. I didn't know if anyone knew where the wires actually ran. Any help? Or any suggestions on where to tie the converter in at?

 

I fit a LOC behind the factory HU with no space issues. I would suggest putting it there.

 

Its a bit tight behind the factory head unit... I agree, but I just managed to fit a Scosche adapter for the JBL system (similar to a LOC) behind there along with an IP bus connector for my aux input, AND about 12 feet worth of RCA cables. Its tight, but as long as the LOC isn't too big, you can stuff it up and to the right above the head unit.... theres some space behind the vent there that I found.

 

I didn't know what an LOC was, but I just saw a picture.
those things seem about the same size as my swi-jack.
I think right behind the glovebox is a nice place and you can easily run
whatever cable thru the dash.

not sure how long the provided cables are, it's possible you may need to craft extensions for them all. would take a few minutes and just clearly label them if you can't color match 22 gauge wire extension.

My Installed swi jack behind glovebox. lots of space.
