Just curious if anyone knows if its possible to replace my front 4x6 speakers with 5.25 speakers in my 1986 Cadillac Fleetwood Brougham (RWD)?

...I replaced front and backs a couple years ago with Polk Audio MOMO's, but im still not happy with the clarity and depth of the front 4x6's.

Also, what will the difference be if I add in an amplifier to my speakers right now?...is it just to make them more louder or more crisp?

Thanks,
