Question about 2001 BMW 330
Thermal issue is shutting down amps till temps moderate. You must be driving your system too hard. And check out your tone control settings especially the bass. Every 3 db boost forces amp to double power at that frequency so if you are already blasting at 100 watts, a 3 db boost will compel amp to put out 200 watts, etc. Very easy to overdrive and overheat amp. You might want to try blowing air over output stages to improve cooling at high volume levels.
You are lucky that you have good protection circuits - otherwise by now you would have blown the output stages.

SOURCE: Radio/Speaker Problem
Check your radio and trunck to see if you have a equalizer/amplifier built in or otherwise.Adjustments would cause radio to go into safety mode.Try your balance from side to side.A busted speaker would cause the fuzzy sound or a shorting speaker wire.If none of this is your problem you may need to take it to a sound specialist.

SOURCE: Problem starting, Loss of Power
The flashing or "blinking" service engine light is indicating an over fueling condition that may damage the catalytic converter. There is a good possibility you have a defective or stuck injector, possibly ignition issue.
Take you car to Auto Zone and ask to have the codes read, they will do this for you at no charge, write the codes down and reply back.
Let me know.
