Ok so im newly familar with the bose sound systems, i would like to add a sub and amp to the system to get more bass, not to the point where i can rattle the neighbors windows, im keeping the factory head unit and speakes whats the best way to do this?? any help or direction would be GREAT!!!! Thanks

 

you're best bet if you want to keep everything stock is to purchase a line out converter from an audio store or best buy. I tapped everything into the harness before the stock amp which is behind the rear passenger seat.
