I believe the rear 4" speakers have 300Hz bass blockers integrated into them, just like the 4" dash speakers. But, if you swapped out the rear 4" speakers for Alpines, you would no longer have the bass blockers.I did this and to me my system sounds worse and it did nothing to improve the rear pods. The only thing I see that changed was my EQ was in the flat position and it disabled the setting for occupancy audio for the driver or all passengers. My overall bass is weaker even when I turn up the EQ settings. I added Alpines to the front and rear and the fronts sound fantastic but, the back is not getting a full range signal even after this setting change. I even removed the pods and added killmat and polyfill and the bass signal is non-existent before and after the setting change. Has anyone figured out what it takes to get full signal to the rear pods yet? Maybe there are bass blockers from the factory going to the rear pods? Any help would be appreciated and I appreciate everything you have done to this point. Thanks
