New Stereo - No Power

[Christian Williams <delorean@xxxx>]

My car already has an aftermarket car stereo in it, but I took it out
today (it was buggy). To get it out, I took off the center console and the
vents (later discovering that I probably could have done it with just the
vents).

Anyway, now that I've connected the 2 power wires and the ground,
this damn thing doesn't work. Does the digital clock, rheostat, and
cigarette lighter need to be plugged in for power to work for the stereo?
I just don't want to put the console back on and find out that I'm still
out of luck.

If anyone's installed a new stereo and ended up with no power, please let
me know what you did to get it working.
