Update - I finally worked out how to get the bassbox hooked up. I ended up taking the box apart and seeing where all the wires went. Then, had to cut off the Porsche/Bose 12-pin connector and used a combination of a 9-pin connector from an electronics store plus a couple of blade connectors for the power wires (since they were a larget guage). I did touch the pos and neg power leads once which ended up in a blown fuse. $3 for a pack of 5 25 amp fuses and I was back in business.

Not bad, but I will need to be very careful pulling the connectors apart each time I have to get the car serviced.

I know people don't care much for the sound of the Bose system, but it does sound a lot more full in the cockpit now.
