Thumping and Hissing Noise from Speakers

I have a 2003 S500 4matic and I have been noticing a thumping and hissing noise coming from the speakers, which continues even when the ignition and all switches are turned off. This started as the sound system intermittently going off after a rainstorm. Now, the battery is completely drained to the point where the car does not start.

I've also noticed water leakage into the trunk, although all rubber seals appear to be intact.

Has anyone else experienced this and can give pointers how to remedy this?

Thank you.
