my last car (99 jeep cherokee) had a really nice all Apline System...

my new car (02 WRX) still has the OEM system (eeeew) and I'm looking to upgrade with Alpine components now that I've already done a little to the OTHER sound system (you know the one under the hood)

my biggest question is will the Alpine R series speakers fit in the doors of a 02 WRX?

also what are some of the problems people have run into installing new equipment in the WRX?

any help would be appreciated... thanks...
