Any tips on which 6 1/2" speakers fit best? What modifications did you have to do in order to make them go? Any special concerns? Did you top mount them and use the cover that came with the speakers or did you fit them below the factory grills?

Did a search for "speaker" and read most of what came up. Everyone says they'll fit, but kind of short on specifics.

Thanks in advance for any help.
