subwoofer in 01 330 ci pops
I have a 2001 330 ci. I noticed I can take a rubber mallet and after hitting a box the size of a pack of smokes under subwoofer I cause the pop. Do I simply replace the box which I believe to be a transformer due to the sighting of copper windings inside? Is it just the connection and will I simply waste my money? What do ya think?
