You may already be aware that the Bose system includes a separate amplifier at each speaker. I don't know how they would interact with your central aftermarket amplifier. You may have to remove the small amp at each speaker before you hook yours up. Bose systems are a mess -- it's the same design on Cadillacs with the Bose system -- it's almost impossible to change your stereo. I'm glad neither of my vehicles is plagued with Bose anything.

They sound great (at least in Caddies), but it's a nightmare to repair or upgrade if you need or desire to.
