i am planning on upgrading the speakers in the rear deck and adding an audiobahn aw1206q in the trunk of my 94 caprice. with the rear speakers using the trunk as an "enclosure," won't the air pressure from the subs have an effect on the sound quality of the rear speakers? i am picturing the speaker trying to play and the sub bumping and moving the mid involuntarily. any advice is appreciated. things i have already considered: 1- enclose the rear speakers to isolate them 2- ditch the rears, LOUDSYSTEM tells me they dont do much for the front seat passengers anyways. i was also thinking this might help the bass into the cabin if i let the empty speaker holes act as vents between the trunk and the cabin. how far off am i? or seal up the empty holes in the rear deck.
