If you enjoy listening to music while driving and want better clarity (which i get a small hint that you do...) i'd recommend overhauling the sound system :) it doesn't have to cost megabucks if you don't go silly :) if you're looking for MP3's why not change the head unit? you can get ones with iPod connectors, AUX inputs, and USB connectivity for well under £100 and even under £50! if you like bass, look at changing the standard speakers for some nice aftermarket ones, the FLI audio ones, while cheap, do offer a nice sound for the money. :) it's more than likely that the standard car speakers are not built to handle large amounts of bass, which is why they were damaged in the first place. and running the speakers without the grills is ok, just watch for dust
