Hello all,
I have gotten a 10 inch sub woofer installed about 3 months ago. And works great till recently. I've notice that when I put on the radio with volume down, the cub makes some weird noises. The noises is like fast thumbing sounds, ( vibrations) is there a quick fix on this? Like a blown fuse or something?

The speakers aren't blown or nothing, they're in prefect shape.

Any advise of what's wrong?

thanks a bunch!
