How do install 6 x 9 speakers in a 92 Honda Civic which has only has holes cut for 6 1/2 speakers?

I have a 92 Honda Civic which only had font door speakers installed. While installing a new CD deck I discovered that there where rear speaker wires already run so I took a look in the back to discover only hole for 6.5 speaker. It looks like without some serious cutting that they cant be installed. Any suggestions?How do install 6 x 9 speakers in a 92 Honda Civic which has only has holes cut for 6 1/2 speakers?I think it would be easier to get some 6.5 speakers any way 6.5 usually sound better than 6 x9 and then sell your 6x9 on e-bay or Craig's listHow do install 6 x 9 speakers in a 92 Honda Civic which has only has holes cut for 6 1/2 speakers?Well the frist thing is u can cut it out.....or u can make an enclosure for the speakers else there are possibly no more options!!!!
