HiFi amp got wet now subs sound blown.
2008 e92 Hifi Non I-drive
I left a soaked rag in the trunk and water seeped through and went into the oem amp and now my subs under the seats sound like they are blown. Every other speaker in the car sounds fine. I removed the amp opened it up and cleaned it and the subs still sound like they are blown.
Is their a way to tell if the amp is damaged or if the subs are truly blown?
