hey, ive got an 86 firebird, and I was looking to upgrade my sound system. I went on crutchfield to check the speaker size and it said 5.25 but on a previous thread, I think glasswolf said a 6.5 would fit. Is there any website I can go and actually check how much depth I have for speaks, measure myself, or just get the smaller ones and be safe? Thanks
you'll be much better off measuring for yourself. It's best to make informed decisions on what to buy whenever possible. If you're gonna replace them, you'll have to take em out anyway. Might as well be before you buy new ones.
