For the electrical problems,
1. Check the battery condition.
2. Check the alternator charging rate.
3. Check the fuses
4. Check battery terminal and ground circuit connections. Clean, retighten and retest.
As to the rear windshield explosion, it is hard to explain. I have encountered cases whereby aerosal cans left on the speaker shelf exploded causing the windshield to shatter.
Not all windshield would shatter due to external factors. Some windshield have self shattered due to stress over time and the heat is an accelerator.
The 2 holes on top of the speaker? Could be the magnetic field of the speakers have causes some stress damage over time.
