Bose rear speaker installation help!
 

I just purchased a used OE Bose speaker box (yet to be shipped from ebay sale) to install in my 98 Boxster with the CDR 210 radio and the system with the amp under hood and door subwoofers. Can anyone help with suggestions as what I need to install the box. I think I'll need another amp and wiring but don't have a clue as to what to get. I've seen the hacks for installing the rear speakers in the storage compartment, but haven't seen any info for installing the bose sub-woofer box. I was wondering if I could wire the small speakers directly to the radio as in the other speaker installation (where radio fader will function) and somehow add an amp to power the larger woofers. I would be happy to hear any suggestions as to how it should be installed. Thanks for any help.
