I'm going with the fronts and tweeter setup and sub in the rear setup, I'm currently connecting my harness with the head unit wiring and trying to figure out how to do this. Since there is two sockets for the non bose setup behind the head unit, I know the large socket is for the front speakers and the small socket is for the rears, do I just merge the rear socket wires with the fronts? I'm trying to bridge the rear with the front so I can push more watts to the front speakers.

 

You're not suposed to merged the speaker wires together.
However if you want to bridge the font and rear together.
You can run front + right with right rear -. And same with the left.(cap the other wires)
Ideally you want to get an amp to run the fronts. If you get a 4 channel amp you can run the front of the two and bridge the other two to run you sub.
Bridging your deck can prematurely kill it. So do it the right way the first time.
But experimenting is fun. Even if you burn your eyebrows.
