i replaced all 4 with rockford fosgate 6.5" speakers.. forget the model number of them right now.. but they too are low profile and fit nicely in the front with no modding and in the rear with a decent amount cutting of the mounts.. they sounded really nice.. still have the rears but replaced the fronts with infinity components.. had to custom do the tweeter pods because the infinity tweeters wouldnt fit the stock location...
