Lincoln Repair Questions? Ask a Mechanic for Answers ASAP
Welcome, I'm Chris and independent contractor that helps customers here.
Normally radio issues and electrical feedback through the speakers is caused by ignition coil concerns and alternator concerns. This bang you get is it just a noise or do you also feel it? Can you make in bang more than once multiple times? What driving condition were you in when this occurred? Can you monitor the battery voltage during these issues, it should be 13-15 volts.
Thanks for letting me assist you. I hope I met all your expectations.

Tell me what kind of diagnostic things you can do so I can help you figure this out?
So you think its possible the noise is the amp and sub woofer thumping?
Being there to hear it makes all the difference.
The amp and sub woofer are in the right rear above the wheel well.
Can you monitor the power to any of the outlets or a fuse with your meter hopefully through this event to see if the battery voltage is out of specs?
Earlier you said its not a coil feedback. On cars designed this way, a coil can act up, it bleeds a RF signal that effects the computer, and this is a computer controlled charging system. So a coil even though not misfiring can effect the charging output which greatly can effect stereo and amp operation.
Noises you hear are the hardest for us to diagnose not being in person. When this noise occurs do you get a feeling as well?
Any luck on monitoring the voltage yet?
As mentioned in my first response, I would stay in contact with you. I've noticed you have not rated the post. So I assume you were not pleased with my help. I hate that you have spent money to get an answer but left not happy. Can you tell me why, or can I help more. If its more help you need just reply and we can pick up where we left off.
