Changing alarm horn

[bigrhino]

I have a Viper # 5701 alarm I was wondering can I change the horn to something different with out going to crazy changing it. I want it a little louder and a different sound.

You should be able to change it to anything that is 12v. I would stay with a low amp draw siren so you don't risk messing up the DEI brain. The sirens are two wire, 12v(red) and ground(black). The wire coming from the brain will be brown, and most likely the installer ran the one wire to the siren under the hood and grounded the neg from the siren somewhere near the siren. You can also use the 12v wire from the brain as a trigger for a relay to up the amps so you can run a bigger siren.

I like to just hook up the stock horn in addition to the siren. When you hear the horn honking AND a siren wailing from your bed one night, you know damn good and well its YOUR truck and not a neighbors. Most alarms have a horn output wire. But if it doesn't, you can still easily add horn honk with a relay and an electronic turn signal flasher.

Been doing that on my alarms for years now. Definitely makes yours stand out since its both siren and horn at once.

The thing I do with my alarm systems is to not install a shock sensor. So, if my alarm is going off that mean that you have either managed to open my hood or are inside my car. People with really sensitive shock sensors and an alarm system that cries wolf a lot will end up getting ignored each time. And yes, I do know, you can dial in a shock sensor to not be sensitive, done it a 100 times. I just don't want any falses with my stuff. I will sometimes add a glass break sensor if I feel my car might get messed with a little more than normal. (I go through a lot of cars)
