My subs, I believe, have some how manage to damage the top part of my dash and there is now a big crack in it. What do I need to get so I can fix that and stop it from cracking even more?

so what you are saying is you have subs mounted in your dash, pics??

dashes crack :eek:

Jacking the truck up in the wrong spot can flex the dash weird, or heat expansion can cause cracks...I wouldn't blame the subs..
