hello, i have a 86 chevy caprice and i was deciding on what alarm i should get, b/c my friend said 2-way alarms only have a 2 street radius and people are telling me that they are in the stadium during a game and they get reception on their alarm? i just wanted to know: WHAT IS THE RECEPTION RADIUS ON THE 2-WAY ALARMS? on 2 WAY VIPER ALARMS? or just in general which alarm is really good that i could put into my box chevy that is a two way or an ignition starter? please someone help? -thank you-
