| Well, the proper way would be to use a switching power supply...

You could also use a computer power supply, but they have a minimum current requirement or else they'll go into protection mode.
Also, maybe a lawn mover battery and a charger.  | |

| Piston, what you are after is simply a 14 VAC transformer with a bridge rectifier connected on the output of the transformer. The trick will be getting a 14 VAC transformer capable of about 10 amps on the 14 VAC side. That will give you enough power to run any size radio you want. If you are running a smaller radio (say something in the 4x10 W RMS range), then you can go with a smaller amperage transformer. I have a 10 amp/14 VAC transformer at my house that I have staged for another project. They can be had. I found mine at a government liquidation place. You can also look in your local area for an electronics shop. You can also look online to see what you can find.
Now, you can try using a battery charger connected up to the radio and see how that works. Some chargers will allow you to do this, some won't. Granted, you can get a small motorcycle battery and use that between the charger and the radio and that will allow the charger to run uninterupted. If you can get your hands on an old car battery, that will work too.
If you need more help with this, just hollar.

| I Use a transformer for my truck at car shows. I use a Honda generator which puts out 110V then the transformer drops it to 12V DC so I can run my DVD in the truck without wearing down the battery in the truck.

| | I have a Sony HU set up as my stereo system in my garage. I hooked it up to a old computer power supply and a switch. The only downside is that it wont save your preset radio stations. I also use the power supply to test all of my 12v electronics. | |
