i've had a box with two 8's(can't remember which models) and a shi**y amp stolen, another time i had a alpine cd player stolen, another time i had two 12 inch mtx bluethunder 12's and a hifonics thor series VII stolen and since then i learned not to bump near your house. I learned don't bump when you're going to park your car Since than i've had way way louder systems and haven't had anyone try to steal my stuff again. I have left my car unlocked and unarmed many a nights on a accident and no problems. Just have to learn the rules of car audio and you won't have to worry about people stealing your sh*t again, and get a alarm
