Right on guys thanx for the info, I've tried everyway possible sideways,up/down rear - front & have come to find firing them towards the back is the best, seems to filter any dist. out plus better for any vibrations coming from the rear dash - these are just two sealed 10s no bandpass/ports here cept the trunk(bandpass :p ) & rear vents (ports

:p ) . Seems to fit nice & snug up against the seats & also NP to remove for spare exit

Again thanx!
