sometime soon i'm gonna be gettin subs put in my 5th gen accord. I'll probably get 2 12's or 2 10's. However, i am worried about 2 things. First, with the 2 12's or 10's in a box in the trunk would i still be able to get to my spair tire? Secondly, If you get subs installed at some place like best buy or circuit city, they don't bolt the box down do they? Thanks
