This might work. Then my concern is the power requirements of the built-in amp. I suppose I'd have those concerns anyway. Since space would be at a premium, I was thinking of trying to do everything with a 12 volt supply - then I'd need an appropriate amp and I'd use the empeg's car dock connections (fitting a dummy jack into the dock to fool it into home mode). This way I can avoid multiple power supplies. My only concern about the small amp in those speakers is the possibile inability to power some bookshelf speakers. I'll have to scour for some specs.

In relation to an earlier post, the price of bookshelf speakers is unimportant - those aren't the ones I want to hack up and put in the case.

Now if only it were easy enough to get a spare dock connector (with some pins, but without all the wiring would be fine). I can make my own dock, but the connector would be an order of magnitude more difficult. Guess I'll have to use the dock from my spare empeg.
