Default Wierd stereo issue

First off, nice forum. I can see hanging around here. I'm new, can ya tell?

Anyway, I'm hoping someone has some idea where I should start with this as I'm not much of an electrical guy.
The stereo (Older Sony Xplode) in my wife's Cavalier recently decided to just stop working. I took the dash apart and both the fuse in the stereo (10amp) and the fuse in the fuse panel (Also 10amp) were both blown. I replaced the fuse in the stereo and checked the wiring in behind for any exposed wires that might be causing a shot, but found nothing out of the ordinary.

I put the stereo back in, reassembled the dash, and replaced the fuse in the fusebox - which blew the second it made contact.
Car was off, key wasn't in the ignition.

A few more things to consider:
- There is no amp. Just the stereo and the original manufacturer's speakers.
- A week before the stereo blew, the acc outlet and the interior light fuse blew. I can't remember if that was 2 fuses or the same one though..
- The stereo has been in the car for well over a year with no issues until now.

Personally, I'm thinking that either I missed an exposed wire in behind the stereo that's hitting something metallic and shorting, or the stereo has developed an internal short. The stereo is fairly old and this is the third car it has been in, so I suppose the latter is possible.

Anyone have any idea what the best course of action is here?

Unplug the stereo and replace the fuse if it pops again with stereo unplugged then it's wiring. If not then its the stereo

Thanks for the response.
I am thinking it's the stereo itself now. We went out for a coffee this evening and realized her interior light is out again, whereas before I started mucking around today, it did work.
Since the radio and interior light are on the same fuse, it stands to reason that the fuse in the fusebox wasn't blown until I replaced the fuse in the stereo.
That would seem to indicate that the short of is in the stereo itself.

I'm going to try reinstalling her old stereo this week. If all goes well, then I'm going to be spending my time trying to dig a CD out of a dead stereo. Whee....
