and know how how to hack in an XM satalite radio into a MY02 WRX?

 

Assuming you just mean install, you need to use an FM modulator since the radio has no aux inputs. A direct-wired modulator is preferable to a wireless one. However the sound quality will not be as good as a line-in connection, if this is a concern the only solution is an aftermarket head unit that has line in or is prewired for an XM tuner.

 

+1 for aftermarket
