Help with a BOSE system

[Ioman]

I have a BOSE system in my car and I would be interested in adding a 12" subwoofer. How would I tie that into the BOSE system without completely tearing it out of the car?

The easiest way would be to get a powered (i.e., integrated amplifier) subwoofer with high level inputs. High level inputs would allow you to tap into the rear speaker lines for the sub input.

Something like this perhaps (I have not tried this product and do not endorse it):

Thanks, I was thinking the same thing.
