Sub won't hit

[Coby_2]

The other dapmy sub in my truck just started kinda missing the beat of the song, the just cut of and stopped hitting altogether. I check and everything is still connected and the amp is still sending power to the sub but nothing is happening

Could be the amp or the sub itself.
Connect the sub amp to another speaker. Be careful not to damage the test speaker.
If it works then the woofer itself is probably fried.
If it doesn't work then the wiring ( input or speaker wire) or the amp is at fault.
