350 Plus - Viper 3-Channel 1-Way Car Alarm Security System with Keyless Entry

 (5 customer reviews)

Good car alarm with loud siren and expandable. Hard to self-install if you don't have any electrical/audio experience but you can install in 1/2 day if you are somewhat mechanical (depending of vehicle).
