I went with this Alpine amp because it was rated more powerful than the OEM Bose unit, but did not need heavier gauge wire than what is in the plug on the outside of the subwoofer box. To start with, I made a mounting plate for the replacement subwoofer amp out of a piece of Lexan. Drilled holes to line up with the old mounting hole posts and then new holes for the amp mounting holes. I purposely shifted the mounting to the right a bit to allow space for the wiring to exit on that side.
