I have a G37 with a stock Bose System and it is horrible. I am confused by the sizes we have and for some reason I cannot match it any alpine speakers

Door:
1" Tweeter
3" Midrange
10" Woofer

BackSeat:
6.5" Full Range
Alpine Electronics of America, Inc.
or
Alpine Electronics of America, Inc.

Rear Deck:
6x9" Woofer
Alpine Electronics of America, Inc.

Dash:
3" Mid

For 3" mids, what can fit there? 4"? or no

Any help would be appreciated
Thanks
