I work for a remodelling company over the summer and on my last job site the woman donated to me two home speaker boxes. they each are a three component system. the 12" subs in either box are blown. is it possible to just hook up the 12" subs that came in my first car that are just sitting around? or would that cause all sorts of problems. or are the subs built for 12v systems completely different from the ones I'd find in a home system
