Default Terminal posts on speaker box getting hot...

This is only like the second thread I started so bare with me....
Okay I had the S15 L7 kicker solo baric sub and a hifonics 1500d subwoofer amp installed at a audio shop back in July. Recently the terminal posts on the speaker box have been getting unusually hot. They never used to get that hot before, before it was a tolerable heat but now it's a unbearable heat ( to the point where you can even put your finger on the post) and keep in mind this happens only about a minute into a song! I mostly listen to rap with heavy bass I push it hard but not over it's limits, and never had any problems out of the speaker or amp just the posts on the box. I was driving home today and wondered why my bass kept going in and out so I turned off the radio( I didn't wanna mess anything else up) and when I got home I noticed the negative terminal post on the box had literally melted away from the housing so it wasn't getting a connection at all. My question is what could be causing this to happen? Any help would be appreciated.

Perhaps your driver is defective which is affecting your driver resistance thus increasing your amperage. If you haven't tweaked with any of the deck or amp settings then the only thing I can think of that would cause this would be the driver failing.

Pull the terminal block out and make sure the wires to speaker is very secure. Im betting a cold solder joint or loose wires inside.

The poor-er a connection is made the more heat it will create as it is trying to send the power through.

Thanks for the advice guys went to a shop today and the guy came to the conclusion that some wires were loose where the connection had been soldered wish I have known some wiring was loose before but the damage is done now so he ordered a new cup and they'll install in Friday and Rewire and solder everything and it should be good to go. Thank you all for all the inputs!
