actually, its unplugged. So techniclly, no, it doesn't serve a porpose, other than to keep a big hole from being in my dash.

however, it kinda has a porpose.... People look in, and see that sitting there especially at night time, when its dark+my tint.

besides, its much harder to steal my HU now. Up top, its kinda difficult to get it bolted down. Most people (including myself h: ) just kinda leave it loose.

down below, there's like 6 screws just to gain access. On top of that, I have the HU screwed in, so its not going anywhere without at least 20 minutes of work and thats if you know the thing. Throw nighttime and no lights (assuming the pull the battery cable), and pretty much no worry about my cd player missing
