Re: I joined this site to ask this question...
It's dependent on what subs and how much power are you putting on them? Ive seen two twelve's sealed make metal panels go nuts. but I wouldn't feel safe even driving a car that couldn't handle a system out of fear of breaking/cracking it. If it can handle vibrations caused by everyday driving without cracking up , it can handle some bass.
