I have a set of subs from my old car that I want to put into the 2000 XJ sport I just bought, but I don't have tinted windows, and I'm pretty worried about a smash and grab. Anybody know anything about cargo covers or some other way to conceal a pair of subs in a box in the cargo space? I searched but mostly found pictures of exposed stuff, sometimes in a jeep with tinted windows, sometimes untinted... Thanks!
