Yep, cheap jvc head unit that came in the truck. Initially I was running these speakers off of the hu. The jeep is a two door, locations are in the front dash and in the soundbar mounted to the roll bar, 4 speakers total. Now amplified, but if I did not already own said amplifier, I would be perfectly happy with the performance off of the "crappy" jvc. They would only perform that much better in an insulated sedan.
