Thanks for your replies today, but I am sending my MTX 9500 15" woofer back to MTX, I expect a brand new woofer in a few weeks, this one is beyond repair according to my local car audio. So I think I will stick with my MTX 9500 15", I just didnt want to wait 2 weeks, but I will, Im going to purchase a Diamond Plate Cargo Mat for the back of my car.
