yea ive been having nothing but problems with these subs so im thinking about upgrading soon, but right now im just wondering if the sub that is getting warm is the only one getting power, and the other one isnt, my box has both subs vented to a single vent so maybe the air was moving my one sub that wasnt getting warm and it made it look like it was hitting, from what ive been reading it is normall for subs to get warm, i would try to hook them up seperate but i have them inside the house and out of the box right now
