frozen sub

I have a kicker 07cvr124 in a sealed box. Also I live in MN. My sub is so frozen I cant move it with my hand. Is this due to the weather or am I looking for a new sub?

I don't think the weather will do that ... I live in the deep south so no real experience with that.

yea... thats what ive been reading. took my box out and sub out of the box and let it sit inside.... still stiff as a rock. already started looking for a replacement.

The voice coil got to hot and lost its shape and now its stuck ,
or the center part of the magnet inside the speaker move and now the coil is stuck
most likely you need a new one
