I also still have such an APC thing lying around.
Thought about the same but:
You could basically leave in the charger and the battery and you´re done.
But this will leave you with a basic 12V PS which won´t get you far.
You´d need another battery and another charger.
But one battery is a start isn´t it?

you could use a SMPSU chip in inverting mode to get -12V...but it wouldn't work well in your case as you are drawing a large current and typically it's also not suited for "audiophiles" because of the switching noise that it makes...you cannot use a 7912 to get -12V...it has to be connected to another battery...and by the way...the 7912 must have a higher voltage for it to regulate properly...and if you are gonna use it for an amp...I believe the 1A current capacity that it has is insufficient...
