Advertising a system...I think that is interesting point, because if you have subs in your car even at low levels there going to be heard, people will know you have a system in there, I spend a great deal of $ on my car to sound the way it does so I enjoy it, Generally i give the people the courtesy(turning it down at lights, when driiving in town reasonable volume, and at night past 10) I have taken much security precaution as one can alarm, bolted down the amp rack, but the fact of the matter is if someone wants your stuff there gonna get it regardless of the alarm. Just my .02 cents.
