I'm looking for new speakers but I find most of the reasonably prices 5"x7" speakers out there arn't too good. Very expensive 5"x7" speakers are good, but I'm not willing to pay that much for speakers

. Reasonably prices 6"x9" speakers sound really good but I'm not sure if I can install them in my 95 Mazda 626 DX which comes origonally with 5"x7" I believe. I found these really good sounding Pioneer 6"x8" speakers, yes they are 6"x8" and NOT 6"x9", and I was wondering if they would fit? I'm hoping since they are 1" shorter the possibility of installing them in my car would be highter, so what do you guys think?
