Im starting to get all my setup in my car now and i was kinda worried about my sub. since i live in Alaska and it gets really cold in the winter i was wondering if my sub could get damaged form the cold. My old setup i dident play them loud tell my car got really warm i was going to do the same thing this this sub. But i just though i would ask to be on the safe side.

Shouldn't be a problem.

unless ur subs are made of plastic and you are burping them with insane amount of watts...then no you shouldnt have a problem....
