Lastly, you could get a proper DC power supply to drive the thing. But
that would probably cost more than a boom box.
My current mini project involves running a car amp, *without* a HU, off a 50
Amp DC supply. I made a jumper from the supply's pos. lead to the 'tickler'
turn-on lug at the amp. When the PS comes on, so does the amp. I had to do
it this way because I'm providing audio straight from my laptop's line-out.
Works fine this way. Next step will be a permanent setup in a small cabinet,
with proper wiring and component mounting.
