hi guys im new the forum. ive own my car for 6/7 months now and need an improvement to my sounds. i have an a3 1.8t 1999, i have a sub in my boot behind a panel. i have seen on the net a jl audio sub with a purpose built box that replaces the original. just wondered if any one has ever purchased this and if its any good. i idealy want to keep my boot free and this option looks good. any thoughts???
