Reversing Stock Sub wires.

Well I am happy to report that I have solved the crappy stock stereo mystery (at least on my vehicle). The two subs in the rear deck are out of phase with the speakers driven by the head unit. After doing a quick swap of the wire position on each sub, WOW the system absolutely cranks compared to before.
This DIY is for those that can't/wont cut and sauder wires while upside down in there trunk.
Step 1
Remove rear seat bottom by pulling up in the middle of each seat position
Step 2
Using a 13mm socket, remove the two nuts holding the bottom of the seat back in place
Pull the bottom of the back forward enough to pass the studs, then lift seat to disengage the hooks at the top
Step 3
reach in the opening where the seat hook goes through and disengage the Sub wire ( the clip is located where I'm pointing with the mini driver
Step 4
swaping the pins is the most difficult part but very do-able even for the less inclined.
Using a pic or small watch screwdriver pry up the pin lock
untill it looks like this
Next with the pin lock that you just released facing up, place the same driver into the end of the terminal and give it a slight pry or giggle while pulling tthat wire, it should pull right out, repeat for for the other wire, then reinsert the wires in the opposite sides and press the pin lock back down
Step 5
reverse the process, kinda self explanitory...

I had to do this as well, but went the solder route. Well worth the effort.
If it has tits or tires it's bound to be trouble........
