I'm looking to put a system into my 2002 WRX sedan and i've come across some questions...

1. What are the sizes of the front and read speakers and also their maximum mount depths top/bottom

2. Looking to get a single-din h/u but what else can i put in the 2nd opening easliy?

 

The fronts are 6 1/2" and can be about 1 7/8" deep(so basiclly nothing with out a spacer), my spacer is only about a 1/4 inch thick but I'v seen pics of bigger ones. The rears are 4" with the insert 5 1/4" with out the insert I didnt run into any problems depth wise here so i dont know the measurement. as for the single DIN thing i got the 2.5rs so i never had that problem, but i think crutchfield sends a pocket wilth the radio if you buy a single DIN HU. Or goto your subie dealer and buy the RS pocket and braket.
