Yup. Been running around with rear seat folded up and box on floor. Easy to pull out if emergency arose and needed seats. Finally said f it and pulled back seat out completely. I don't even have a large system but was tired of messing with restricted space.Sounds like your friend's a pussy and wants the availability to remove his enclosure if he wants some friends to ride with him somewhere. A hardcore basshead would rip out the back seat for the space to put lots of speakers //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif
