wuts the difference between these 2 way viper alarm system? 791xv, 690xv, 591xv?!! it says ones 5,4,3 channel, and 2-3 aux? those r the only difference? if i wuz juss going to get the 2 way alarm should i not choose 791 and choose 690 or 591 to go cheaper? wut r those 5-3 channel and 2-3 aux things?

 

not quite sure all the differences. I think the 791 and 690 have my aux outputs.

 

The Viper 791xv is a 2-way alarm and remote start system combo with keyless entry while the 691xv is just a 2-way alarm system with keyless entry and no remote start.... The 591XV is just a remote starter without security. Get the 691xv if you just want a security system or the 791xv if you want the remote start with security
