I was going to have Frodo check my grammar before I posted this but I don't think he's online
Back in high school I had a nice Alpine amp mounted under the rear seat and a custom sub enclosure bolted to the tailgate of my Jeep Wrangler. When I had them installed I made sure they used four different screw heads to bolt the amp down and at least two different sized bolt heads to secure the back seat to the floorboard. I figured if a thief wanted it they would have to bring a toolbox. An they did. I came out one morning to find my entire back seat sitting neatly on the driveway next to the Jeep, all screws and bolts intact and wiring neatly undone. I didn't leave the faceplate for the headunit in the car, so they took a screw driver and destroyed the thing. While the cop was taking the report I asked him what could be done about it. He suggested I get a new stereo, a case of beer, a few friends and wait for the bastards to come back.
