is it possible for you to post a couple pics of what the setup looks like? I posted in the audio and tech forum about being interested in swapping out the stock sub for an aftermarket and was also told that I would need to get a custom box made.
space was one of the reasons I also bought the 16 rdx but if it means I gotta take up some space back there to get better sound, I might just have to do it
