go with viper.... im not sure what the prices are up there, but down here in bama, i install a basic viper alarm, the viper 350 plus for $249.99.... no opinion on the kole audio part.... never dealt with it....
haha, if youre in alabama ever, stop by tuscaloosa.... ill install it..... we charge $150 labor for remote start alarms brought in by customers.... plus any bypasses youd need.....
i installed one our fresh installer trainees truck, and the interior dash lights flished but the exterior parking lights didnt flash untill i did the key bypass. he has a 06 silverado......
bought it on tuesday, and i love it..... for some reason, "dead and gone" is one of my favorites to just listen to, and "ready for whatever" is my favorite to beat.....
