Okay i have said it before but here is my tip towards keeping empeg and car secure.

Get an old wiring harness or make one out of some wire and crimps so it looks like you can plug in a stereo to it. Now attach this to a small piece of wood slightly higher than the empeg this then goes into an empty cage and locks in leaving a bunch of wire hanging out of the dash which looks like someone has already stolen your head unit.

Oh yeah and don't leave the empeg in the damn car !
