i made a thread named "external power source"
its very similar to this thread but in mine i needa run 2 amps.
what ive done is i bought a 40amp regulator from jaycar for $200.
it supplies a constant 12v source and 40amps. it attaches to the battery terminals ( not using battery) so you bybass the battery alltogether.
it runs for ages, only thing is after about 1-2 hours of loud solid music+bass it tends to heat up.
hope it helps. if not, ahwell

When I said it does over 14 volts...I meant it does OVER 14 Volts. MOST battery chargers will do this, not just the cheap ones. But it is not a continous supply of power. Although it's not AC it does switch on and switch off at set cycle rate.

A cheap charger does not switch switch on/off at all. Its simply a transformer and a couple of diodes.

Well i can only help you with the power side of things, theres 101 ways to mount speakers etc etc.

You will need something like this:
13.8VDC 0 to 12 Amp Regulated Power Supply - Jaycar Electronics

Then just connect the yellow and red wires from the stereo to the positive terminal of the power supply, and the black wire to the negative terminal. Then obviously speaker wires go to the speakers. Turn the power supply on and youre away!
