best car alarm, 06 denali

You are going to get lots of different answers here, and to be honest in most cases you can get a very expensive alarm but if not properly installed it's worthless. My opinion is something from compustar they are the best for range and they have some pretty cool features. I would say the pro2w9000fmas. But you may also want to look into some sort of gps tracking maybe also from compustar it's called computrack

i agree"dont ground out!"

Compustar 2WSSASCris

cool ill check those out. im getting installed locally at a "professional" place so i hope im covered there. when i called all my local shops they all said viper 5900, any thoughts?

I personally don't really like dei products I'm more of a fan of compustar or autostart. I've had some problems with dei mostly with range

DEI is great if you can't get any Compustar. I just upgraded to the 2WSSAS from the 5900 and I love it. The Viper is complete junk when compared to the Compustar. I would get horrible range and have to swap out a new battery every week. The shops telling you to do the Viper didn't carry Compustar I take it? Where are you located?Cris

You should be fine with either DEI or Compustar. I prefer DEI because that is what I sell and I can tell you that I have very few problems with them. The most important thing in your alarm is going to be your installer.

i would go compustar all the way, too bad here in canada we dont got the P2WSSR - AS yet, only have the P2W900FM-AS =( also you can add on computrack which you can use a browser and monitor status of your car.

Do you guys in Canada get the ones where the brain sense the remote approaching the car and unlocks it for you? I wish they would add that to the US models.Cris
