[QUOTE="keep_hope_alive, post: 7370467, member: 576029"] notice how the rear speakers are mounted in doors that have lots of holes. it's like listening to a speaker while holding it in your hand. the back wave combines with the front wave - causing cancellation. this is why they lack midbass output and sound distorted in midrange. seals that make the rear cavity air tight are the key to good midbass and clear midrange. some sheet metal, silicone or foam weatherstripping, and self piercing screws can easily seal up those holes. i use weatherstripping foam at every speaker. closed cell between speaker and metal. open cell between speaker and factory panel/grill. without closing the holes, you rely on the plastic panel to cancel a back wave. here is a good build log to get examples of what i'm talking about.
