I have the DI slipstream on my JLU. Overall, I like it, I will say it is kind of a PITA to install. I have very little rattling issues with the sub, only a few songs seem to hit the right frequency where I notice any rattling and even then its been pretty minor. The main issue I've run into is that I wish I would have waited to install it until after I'd installed things like my rear bumper w/ tire carrier and my CB radio because wire/cable routing is a PITA or impossible without being able to remove trim pieces which is greatly compromised by the security enclosure being installed. Fit/finish is really good though, valid point about the use with a soft top and the bolts for the side wings being accessible. I doubt many thieves would be motivated/prepared enough to bring tools and use them to gain access but I guess you never know.
