i have 5% tint all around (can't see crap when the windows are rolled up), plus I always take my BLACK t-top covers and cover everything up everytime I get out of it. fits perfect, plus you can't even tell there's a system in it. Also i'm not one to go around showing it off to everyone I know, there's plenty of friends of mine that don't even know I have a system. Anyways, there's no way to prevent stuff like that happening 100%, otherwise nobody would get their cars stolen. That's the chance you take when upgrading. I appreciate your concern though :)
