Decreased audio volume audi a4 (paypal for the actual helpful solution)

[Enveras]

Just as the title says. I've noticed my audio volume dropped by a lot recent days. I've been messing with the settings in car's infontainment system, reconnecting aftermarket subwoofer and amp. Not to mention I started hearing some speaker buzzing on my right (passenger side). Every other speaker seem to be in perfect condition. Can this somehow be related with the original (stock) car's amp? I aswell had my subwoofer installed a few months ago, don't know if this have any impact on this current problem, but I'll let you guys to decide that. Nonetheless, I wasn't playing with the settings before it all happened and neither I was torturing my audio system with loud and "bassy" music listening.

A blown speaker could be causing your factory amplifier to turn off. I would start by disconnecting the buzzing speaker.
