Just wanna replace my 1997 OEM pieces o' crap ...

I need:

2 Tweeters
2 Front Door Speakers
2 Rear Deck Speakers
1 Rear Deck Sub

It's an SC300, so I think the factory sizes are:

4" Fronts
6" Rears
10" Sub

I don't wanna have to modify the fronts though; so I think 5" is the largest I can fit, easily. In the rear I can fit 6.5's.
