howdy,

 Come to think of it, get yourself a BIG dumptruck or
Caterpillar battery. If the cell connectors are not
exposed, you can drill one hole EXACTLY halfway
between the posts on the opposite side of them. About
1/8" to 1/4" down, you will hit lead or some other
metal. Put in a screw and there is your 6 volt tap.
Now, on the post side you will find 2 cell connectors
about 1/3 of the length from each post. these are your
2 and 10 volt taps. Go back to the side with the screw
in the center of the length of the battery and measure
out 1/3 of the length and this is where you'll find
your 4 and 8 volt taps. If you draw 6 equal cells on
the top of the battery this will be easier to see. If
you don't find the cell connectors, just seal the hole
back up with silicone. 9 volt stuff will do fine with
either 8 or 10 volts. Casio and Yamaha at 7.5 should
do fine on the 8 volt post. A car stereo amplifer will
give you your volume. As I said before, for bipolar,
use 2 batteries. Anything that runs 15 volt bipolar
should do OK with 12V. After your done, unhook the
batteries, wire them in parallel and AFTER you start
your vehicle, hook them up to the vehicle battery.
They will charge merrily all the way home.
