The choices are Viper 5900 or the Compustar 2WSS-AS. I want trunk protection as well as glass break and if it is there shock the hell out of someone that touches the car, sorry about that. Starter disable and battery disconnect built in also if possible. Let me know the in and outs of each from people that own these. They just took the face of my stereo and broke glass out on pass. front and took dash apart a little, nothing to major; THIS TIME.
