Thanks for your reply, but I originally contacted BSW to purchase the ib110 by itself. I absolutely want a new sub and amp as the factory "Harmann-Kardon Premium" big whoopdy-doo hoo-hah sound system is absolutely pitiful on the low-end.

The PAC module he is referring to is the PAC SWI-X unit (also something I requested) that allows you to retain use of the steering wheel controls over IR.

BSW is quite reputable and they are not trying to push anything on me. Sorry I didn't give a little more background.
