I think putting a 5.1 Epic 80 setup in a jeep cherokee is the best idea ive heard in quite a while. You can probably lay the M80's on the dash and possibly mount the Vp150 off the rear view mirror. The sub would probably fit in the back great. What do you plan to drive them all with? As far as i know there are no 5.1 car amplifier's Definetly send pics when you get it all installed \:\)
