2000 Dodge Intrepid stereo/alarm problems

I've had a problem with my alarm randomly going off after I've locked my door with remote(doesn't happen when I lock my doors manually). Usually happens when temps are warmer, around 80 degrees. Now my radio is not working. The last six months or so the right speakers have been very quiet. I figured the right channel in strereo was going. I had it in for service today they left the key on to be able to turn the wheel (they were doing and alignment) and they said they had to jump it to start it. They put it on a charger for 1 1/2 hrs. Then I went to put on the radio(which they must have turned off) and it was not working.
The equalizer buttons were flashing. No time or anyting came on the screen. Any ideas?
