i have a base CT which didn't come with a subwoofer. i have a spare 10" Harmon Kardon sub from my old home theater system that I plan on reusing in the CT. figured i'll need to get a new amp for the sub and build a plywood case for it.

question is.. has anyone been able to have that added to their CT? i'm not familiar with the stock radio unit, so not sure if it even support a sub input. would appreciated if members can share how they went about in adding a sub. thanks.
