I have just got this system installed on my car. It is "supposedly" the best. My friend has this on his prelude. he has had ppl break in and what not and wires ripped out and cd players stolen but never has the car moved from where he parked it at. and he lives in downtown ATLANTA. Pretty cheap and simple. And they say they never have had a car stolen with this system in it!!!

 

or u can save urself $300+ and make ur own
