I am assuming that everyone downplays rear fill due to the poor imaging provided by OEM speaker locations. Would adding a quality rear fill have an increased effect if you could change the imaging?
I have a large rear backseat and am considering running a set of midbass or comps using a fiberglass panel down the middle of the rear seats OR mounting a set on top of the rear deck using fiberglass pods to point them out instead of up. Would this not create a noticable change in the rear fill? ...or is this just wishful thinking?
