I am going to hook up a car stereo inside a weatherproof box on my deck and I need to find a power supply to run it. I want to find something that I can plug into the wall that will supply enough 12volt power to run the stereo.
How many amps does it need to produce to avoid tripping the unit? Most of the ones I've seen at Radio Shack, etc., only produce about 10 amps. Is this enough? I am going to hook up 2 of the Bose indoor/outdoor speakers to it, and that's all.
Any suggestions for a small, reasonable, power supply that will do the trick?

It's easy, just buy a AC/DC power supply 12 -14v and 5-10 A. that should work fine. Also you can get a computer case power supply which work just fine, just find something to isolate the power supply.

Ideally get the rating off the nameplate.
Unfortunately 12v automotive equipment often doesn't give input power or current so the next best is to measure it connected to a battery. A cheap multimeter will measure dc amps.
Choose a power supply a little bit bigger than what you measure. Make sure its well regulated otherwise you will get ac hum and may even damage something.
10 amps would actually seem more than enough. I used to run automotive CB equipment from a 13.8v, 5A regulated supply, these are sold in the same place as CB radios and would probably do your job.

For a standard in-dash car CD player, a 10-amp power supply will be more than enough. Since you're only hooking up two speakers, even a 5-amp power supply would probably work.
Here's a 6-amp and a 10-amp unit for a decent price:

Get about 92 volts AC from a transformer. Connect this to a bridge rectifier to give you pulsing DC with peaks of about 130 volts. (92 times square root of 2 is 130 ) Connect a large capacitor of 5000 uF rated at 200 volts or more across the output of the bridge rectifier. Take the output from across the 5000 uF capacitor. This will be close to 130 volts. Put it all in a box so nobody can touch it.
