theoretically....could u buy the harness to add an amp to bose..and connect an amp the speaker wires at the doors and BOOST the sound coming OUT OF the bose amp so that u get louder sound? would that work?

 

Pretty much, only do it if you have to. My pioneer went south on me this summer so I had to put the Bose back in, I'm currently only running the sub amp off a line converter and just using the regular Bose door and rear deck speakers for highs. If you need to run more than a sub amp just run a line converter from the back speakers and then to your amps/crossovers that way.

 

Why waste your time? Rip that sh!tty Bose out of there and replace it.

 

Actually the answer to your question is "NO".

 

+1000 on that comment.

 

how about if you hook up subs in the trunk using the wires that are used to connect the Bose sub?? could you just use the signal wire (or what ever else) that goes into the Bose unit, and put it into aftermarket subs in the trunk??
