The stealthbox JL came up with for the E92/E90 is lame. The whole concept of the stealth box was to integrate a sub while keeping the factory look and factory function of the car. That stealth box blocks the rear fold down seat and it looks like someone just slapped a pair of 12s in the trunk (I know they are 13TW5s). Totally not worth the $1000+ they want for it. Crappy effort by JL on this one.
