What is wrong with my sub?

Question

When the problem occurred, I only had one 12'' kicker cvr hooked up to a zx300.1. The gain on the amp wasnt even all the way up and the sub started making a rattling noise when played loud. I then added another cvr and the gain even lower than before. I definitely know that the sub isnt being overpowered, and the amp isnt destorting or clipping because the other one is fine. So what is wrong with my sub? I think it may be to do with the box because when I push down on the box hard enough it stops...is my box just falling apart? Is it bad for the sub?

Answer 1

ya its probley the box if its not that then its the subs voice coil is broke  

Answer 2

yea just take the sub out of the box and buy white or black silicone cauck and use staples not screws to fix the problemed areas of the box cauck the S**t out the inside of the box all corners top to bottom left to right
