For anyone interested, I contacted Bose and asked them for the spec sheets on the 07 model Studio on Wheels. I had read several posts on here about people upgrading their audio systems, but most, that I read at least, were pre-2007 or non-Studio on Wheels systems.

The Studio on Wheels has different size speakers compared to several of the posts I've read on here:
10 speakers
Front doors: one 1" tweeter, one 3" mid/high, one 10" woofer
Center: one 3" in center of dash
Rear doors: one 6.5" full-range
10" sub on rear deck
