Sony stereo mess, need wiring help

[v8only]

Hi all, 2001 yukon...Sony bt4100p radio. new truck to me. Front speakers work, and a factory sub in back works (sounds like crap) but rear door speakers don't work at all. It's obvious previous owner didn't wire it up right, but I can't find the right diagram for this plug. I need to know which wires out of the factory plug handle.which speakers, including the sub, thx all!

Lol got it to work, resetting radio did.it. Sub sounds like crap, flap flap pop, think it's blown, I assume I can't just swap it with any 8" sub?

There are a few aftermarket, higher quality subs that will fit with minimal work in the factory enclosure. I think I saw a write up somewhere on the site, can't find it now, maybe a member who's been here longer can help more?

better off going with a standalone sub!

v8only I have the factory sub from my 02 suburban I would be willing to sell you if you wanna stick with stock. Send me a PM if you want it.

This is what it looks like.

bypass factory amp behind your glove box and run speaker straight off the head unit. Add an aftermarket sub if you want it to sound decent.
