Two-Way Car alarm

[Robert Wollenberg]

To set a shock sensor you'll need to test it. With the alarm armed, you hit various parts of the vehicle to see how much shock it takes to get it to go off. You adjust it until it's where you want it. That's why I use several shock sensor. Rather than have one shock sensor under your dash to protect your whole car, I put one in the back and one in the front at a minimum. If I'm really energetic that day, I'll put about four sensors in. That way each sensor is more specific to a certain area and can be adjusted much less sensitively.

I'm assuming additional sensors will cost more money?

I'd probably mount one under dash, under seat, and in the trunk if it isn't too expensive lol

dual stage shock sensors are probably about $12 each. When I do my Jeep I'll probably have on in each rear corner behind the tail lights, and one on each B-piller. Not too many people come in through the windshild so I'm not too concerned about getting my shock sensors too far up front. I'm more concerned about the side windows and back window. Besides, regardless of how many shock sensors you have, if you only have one, someone breaking the windshield will set that one off for sure. lol.

you only need one shock sensor. it covers axle to axle.
same with proximity.
every car will use a different sensor level, so asking what other people use for theirs is pointless.

the glass bearkage mic is tuned specifically to the sound of shattering glass, which an impact sensor won't detect if someone crushes a sparkplug in a vice, and throws or slingshots a piece of broken ceramic at a window. This will however, disintegrate a window on contact.
It was a way devised in the 80s to bypass shock sensors.

I don't like that fact that the shock sensors tend to be more sensitive in the area they're mounted. If you mount one up under the drivers side dash, you can set it off pretty easily at the drivers door window, but damn near have to break out the back window to get the warning beeps to go off. That's why I like multiple.

One will work. If you mount it in the middle of your car like under the center console. I just like to use multiple. One sub works great but people run two or more all the time. Sometimes it just makes us feel better. :)

two sensors are fine.
"one under dash, under seat, and in the trunk" is a bit silly.

put two in, at opposing corners. all you should need.. although a proximity sensor will protect everything from axle to axle evenly as well.

Thanks a lot guys for the info. It's helping a LOT!

So guys, I went to my local shop who does Clifford, Viper, and Compustar. All he had in stock was a 1 way compustar. He told me that he doesnt' like compustar just because there is only 2-3 dealers relatively close and that they aren't too familiar with compustar.

He suggested a Clifford 10.5x or 5.2x or something like that. He quoted me around $450 installed. Comes with everything but remote start.. anyone else have experience?

[Robert Wollenberg]

I've always been a viper fan. I found an online site to get a viper 791xv for $240. I love installing alarms and will do that myself. I wouldn't think of letting someone else install my alarm, or anything else for that matter.

I'm still shopping around for better pricing, but this is probably what I'll end up getting.

Haha.. if only I could install it myself, would save me like $200.
