Man I think you shoud go with the pager consept. That way if someone's breaking into you car you can sneak up on them while there still trying to do the drity deed.

 

Yeah, i had the autopage 750, on my truck, and my girlfriend has the 850 on here accord. the problem is that if you are too far away, you wont get a page. I live on the 25 floor of my apartment, and have a far, underground stall. my old one would get notified about 50%... the Compustar is supposed to have really good range, but it's pretty pricey. in fact to get any autostart alarm put in( most pager alarms have this capability), you have to pay about $700 dollars total, you can get the new DEI Viper alarm which has a gps locator, for about $1500. But since you already have an alarm, i would go with the airhorns. That would be the cheapest insurance for a really loud alarm that will work with your current setup. If you want, ask the installer to put in a cutoff switch, so you can turn the horn off, or on for like when you are in a really quiet neighborhood. This Really works good. i promise!

 

Did this help you with any on your questions? which method are you considering.

 

I just wanted to say I found this thread very helpful. Thanks. (bump from the grave)

 

^ was that necessary??

 

I have a audiovox factory upgrade alarm that has a siren, and I installed two Freeway Blaster horns this weekend. These horns have been upgrades for the past four cars I have own because the OE horns usually sound like a scooter horn. Siren and horns sound off together.

All alarm sound are controled by noise pollution laws so there really is no alarm that is louder than another once you reach a point. However you could always get a 2 way or an extra siren.

 

iput the extra siren, its annoying for sure.

 

I got a backup siren installed and when the alarm is triggered, both of the siren go off at the same time. Pretty friggin loud! And in case the power is cut off from the alarm system, the backup siren will still go off.
