I installed this with a Clifford 50.5x in my 2001 silverado. I haven't gotten any false alarms with my system but I took it to an empty parking lot and tweaked it pretty good.

If you set it up right you won't have any problems, placement doesn't really matter as long as you don't do something weird like stick it inside a pillar or under the carpet or something.

Just grab some 3m double sided sticky tape (something good so it will hold in extreme heat) and stick it somewhere it can have air space around it (at least that's what I would do / did). I stuck mine behind the center console; Plenty of air space around it and you can't see it.

Play with the sensitivity until you are happy with it. How I tested mine was using my key-chain, 1-2 keys is good, just grab the ring or your remote on the key-chain and tap the glass (tap lightly, don't go scratching your glass!!) with the keys. This will simulate the frequency of breaking glass, and you can tweak it so you don't have false alarms...

I'm about to install a Clifford 50.7x in my wife's 2007 300, I'll be buying another one of these next week :-)

Good Luck!

My truck was boken into 3 times. The first time, I had no alarm, but the cops caught the guys! The second time I had the alarm on, but was set too low and they got into my bed-mounted tool box (put a pad lock on it after that). The third time I was in bed awake watching tv. As soon as they poped the glass ( I heard it) the alarm sounded and they took off. This sound sensor did its job! After this third break in I added the Radar motion detector and had the dash security light changed from red to the much brighter blue.
If you are thinking about putting an alarm on your truck / car, I recommend getting the addon sensors! Like me, you may whish you did.

Got this for my Viper 5900. Had the sensitivity up too high, a helocoptor flew by and set it off. Put it down a little bit, and it'll go off if I say "pssssssst." I don't think a shock sensor is enough to detect breaking glass, plus this thing plugs right in along with the shock sensor.

I installed this sensor's mic on the middle upside of the rear glass of my Corolla with the supplied 2 sided tape. The receiver at the trunk so it could be visible when it's opened and therefore easier to calibrate. The microphone picks sounds of highwave frequencies and triggers (-) into the blue wire (you can try hitting a glass bottle with some metal). it's simple, all the work I've to do was running a blue cable from the dash to the trunk. I just installed at back because thieves tend to break the rear door little triangle glass, instead of the larger door glasses, this works for them in many cases without triggering the full alarm, because shock sensor don't always pick 'shocks' from the back of the car when pressed toward using force on the door. Don't spec to see a big glass to be broken!! that will make a lot of noise and vibration to the car, so alarm with be on!!! only desperate theft fall in this category. I recommend this item, it offers more security to your car and all your valued items inside.

I installed this with a Python 991 in a 2004 GMC Sierra. After tweaking it the sound of 2-3 keys clinking on my glass triggers this sensor reliably and I've had no falses. I'd recommend this to others.

This unit works great! very easy to install and very easy to set up and test. The led comes on every time the mic senses sound making it easy to adjust. I wish the other add ons I bought for my Viper were so simple to install and use.

I don't know know if it was just a batch of bad alarms, but I ordered one and had it professionally installed and the brain was bad. I then ordered a second of the same type and had it installed by best buy again then another company and neither were able to get either to work. Both said bad brain.

I added this sensor to the Viper 5902 in my '90 Jetta. It works great, and is a quick/easy install. To mount it, I drilled a hole in one of the dash blanks and inserted the microphone sans its mounting clip - looks very stealth and OEM. Highly recommended.

i havent had a chance to test the product, but again the only way to test it is to break a window on my vehicle. Still, I am very happy with my purchase. I am thinking about getting a few more accesories for my alarm system. Amazon is the top seller in my list.

Installed in 2009 Accord V6. Not a real must in every security system, but as I went all out on my alarm I figured I'd truly go all out. 2way FM(6000' range), Window modules, R/S, remote sunroof open and close, dual shock sensors, tilt sensor, proximity sensor, AND glass breakage sensor.

Placement is key for even coverage. I removed the mic from it's bulky housing and crafted a much smaller bezel putting this in the bottom part of the center console. It is almost invisible but a gentle tap of a key on any piece of glass sends a pre-warn. Although it will pre-warn with jingling keys occasionally :p

DEI has always been the brains behind the mayhem in the automotive security sector, this lives up to Directed's rep. :)
