want to add in cabin siren

I have an Clifford Solaris G5 with all the add ons.. Id like to add on of those Piezo sirens in the cabin like under the dash, or seat to deter theft a little better.. Can I just tap into the exsiting siren wire and piggy back it into the cabin for the new siren?? I had a dude follow me home when he had heard my bumps on the freeway. (i have 2 RE MTS12's 2US MD3D's 2 Sets of XXX Comps and an US 4320HC so i kinda like my stuff and want it to be there in the morning when i get up) I do have 2 inline kill swtiches so my car would be kinda hard to steal and ive used security screws (2 types) on my entire install so ive taken alot of precautions.. I figure no-one could stand a screamin 120DB's while tryin to get out security screws!!

you should be able to tap into the main siren wire. I would play it safe and use a relay.

85 - ground

86 - alarm siren output87 - constant 12v fused @ 5 amps30 - to both sirens (+) input

Hey thanks alot man!! I added to 120db sirens inside today along with the relays you recommended.. Man this thing is lethal on the inside.. I couldnt stand it for more then a few seconds, it really is that painful.. Thanks again!!

Did you put piezos inside or regular sirens? Does it really matter which kind you put inside?

he placed piezo's. it doesnt really matter what goes inside, but the piezos have higher pitched sounds so its more harsh on the ears.

So 1 piezo inside the car would be plenty? I know a perfect place to mount it also... There is like a 4" depth space behind my glove box. I could mount the siren to the back of the glove box and have it facing downwards. The only problem is that I dont want to wire it to my siren output. If I do so, then I will have problems when programming my alarm for any reason because the siren chirps when I enter programing. Is there a way that I can hook the piezo to the siren output but have it delayed? Right now I have 2 sirens mounted under the hood. I have them powered by a relay. I would run another wire off that relay to go to the piezo but I want that to be delayed. When I arm my car, the siren chirps once. I can hear the relay trip. Its triped for not even a second, and is like that per every chirp. So I would need like a 2-3 second delay. Any ideas?

you can get a delay module and time it for 2-3 seconds. i think DEI has them for around 30 dollars. i would also advise you to put a diode on the siren output wire closest to the siren with the band facing the siren. In case a theif does find one of your sirens and grounds it. it prevents the other sirens and the alarm brain from getting shorted. can you post where you got your security screws from? I am very intersted in getting some for myself. do you know if they have ones for speedlock?

A switch would work perfectly BUT what if I need to break into the car (not actually breaking the window but you know) and need to manually turn the alarm off, from the time the door is opened to the time when I get the alarm to disarm, I would need to put up with that piezo blasting.

that is something you will have to live with, remember your trying to protect your car. i guess 15 seconds of pain is well worth it when it comes to protecting a good investment of audio components.
