Saturn SL2 speakers

All the speakers in my g/f 's saturn SL2 are blown.. i was wondering if anyone knew what size the speakers were and/or what are some good replacement aftermarket speakers i could get that are within my college student budget. thanks!

they are oversized 6.5", in other words about 6.75". not everyday speakers, i used 6.5" and drilled new mounting holes.

I bought Pioneer speakers from Wal-Mart and hated them. Order the factory speakers from a place like A. W. Golden. If your girls car has the high end stereo (equalizer) you will be impressed with the results. Saturn was ahead of their time regarding economy car audio quality.
