When my car got broken into I didn't have my stock cover over the empeg metal harness, but now I always put the plastic thing that was there before the empeg back in when I'm not in the car. Luckily my empeg wasn't in the car when it was broken into. But now you couldn't tell that it had any modifications when it is parked. And I keep my empeg in a padded fire safe (Sentry 1100) when it is parked.
