This is amazing! Definitely worth the money. I used this pack in my 05 Jetta GLI. You can see pics and video of it on the internet. Just make sure you take your time and cover all the problem areas. You will see an increase in bass, sound quality and extremely low to no rattle. In doing research on the internet it said that most trunks can be covered by 20 sq ft. However, after doing my trunk we found that 40 sq ft gets the job done. So when you order keep that in mind. Also, all the carpet in the trunk makes it look smaller that it really is. Once this was removed the trunk was big enough for me at 6'2 to sit comfortably in it to work.
