Hello, my name is Rusty. It could be the head, the amp, or the speaker. The first thing to do is expose the door speaker, and make sure both connectors on the back of the speaker are tight. Then you'll have to check the speaker connections at the amp. Then check the input wires to the amp, and make sure your connector on the back of the head unit is tight. You'll have to just follow the signal back from the speaker to the head and find what is loose.
