Thread: Aftermarket tweeter help

So I'm looking at Crutchfield.com. looking at rockford fosgate component systems and I'm getting things narrowed down and it's telling me that no aftermarket tweeter is going to fit in the stock housing? What needs to be done to make these fit? Also what needs to be done for say 6 1/2 or 6 3/4in speakers to fit into the doors?

It's an 02 and just trying to get everything going. It's all rockford except the head unit. I'm upgrading that with a hands free call too and the unit comes with a mic but have no clue where to put that either! **** I'm clueless sometimes!
