Here is an example of a good idea that could use a little tweaking. Someone has disguised a subwoofer as an innocuous carton of Miller Lite. This unit is actually designed for home use, but I see potential for it to work out as a great type of stealth security for a car audio system; except if you are using it to hide your electronics then you might want to go with something that does not contain alcohol and does not appeal to degenerate thieves, something like prune juice. For me, Miller Lite falls distinctly into the same category, but I don’t think someone who breaks into your vehicle is going to be that picky. Anyway, it is kinda cool, though I don’t know that I would rather have a carton of beer in my room than a subwoofer enclosure.
