Will be getting new speakers soon and wanted to know if anybody has put 5.25 speakers in the dash on a Firebird ('89) I know there will be some modification needed, but how much exactly?? Any pictures? Thanks

If you have the factory 4x6 spots like I did, I just got the plate style speakers.... I think they have little 3 inch plus a tweeter..... Always remember that round speakers make better sound than oval.... You could even go with 4 inch 2ways....
