Apart from those expensive speakers that anyone can see installed in the back of your car.

Nope, my speakers are under the factory grilles and you can't tell that there's anything there at all other than the standard speakers. Stealth is a very important part of my installations.

Empeg stickers on the windows also provide burglars a very nice option to pick out those cars which most certainly have (expensive) amplifiers and cables installed.

Only if they know what "empeg" is. I don't have empeg stickers on the windows anyway. My license plate, on the other hand...
