wiring 2 sirens parallel?

Ok, i have the standard alarm and a piezzo alarm for my setup, I heard somewhere that to wire both, on the output from my viper 5002 (brown wire), I would need to wire in parallel..  I remember the terminology i think, and just wanted to get confirmation...  Does this mean  the + wire goes from the viper alarm to the positive side of the siren, then the negative wire exiting that siren will go to the positive of the piezzo siren, and the negative wire of that piezzo will go to the ground..    Does this sound about right?  thanks for the help

No that's series wiring and its unlikely you will hear either. Take the brown lead to the pos (red?) on both sirens, ground the neg (black?) on both; thats para wiring.

the viper unit might not have enough current output to run two sirens. i have seen it done, but it might burn the output. you can do it the super safe way and use a relay.

85 - ground

86 - 12v siren output from unit (brown)87 - constant 12v fused @ 5 amps30 - to both red wire of siren

Like tedmond said I would use a relay.  I know it's just a piezo your adding but i have seen DEI's siren output burn up pretty easy.

What exactly is the sense of having 2 sirens? I mean my siren isnt that loud due to the fact that I have a body kit making it harder to escape from under the car. I can hear it  but its not crazy loud.

appreciate it guys, I might just do the relay to be extra safe.  love this site.

 to the person asking, i'm putting the piezzo siren inside the car to annoy a would be thief even more - or make his ears bleed atleast lol.  thats the point.  the piezo was not meant for me to hear it outside, thats the job of the main siren.

I understand that. Is there a reason to put 2 main sirens outside the car though? Also, where is a good place to mount the piezo siren? Another thing.. If you wire those 2 sirens togther, than when you arm and disarm the alarm, both sirens will sound. Is there a way to have the piezo only sound when the alarm is triggered, or a door is opened?

well some like the EXTRA loudness, but one is sufficiant and one piezo inside is WAY more enough ti kill the guy ahah. The best place to mount a piezo siren inside is under the glove box area or really high up in the dash facing the floor so it reflects more. The only way to cause one siren to go on is if your unit has the option. Most units have the HORN(-) and SIREN(+) output, and also the ouputs can sometimes be programmed. eg you can set the HORN to work when remote starting but SIREN for door trigger. i know the asianwolf doent have it, so audioman i guess your out of luck. also   audioman, the siren in your engine bay, allign it so it face the floor OR face it towards the struts or chassis, this should help you gain those extra db's.

There is a way to make a delayed relay.  I have seen it here on this site before.  Maybe the forum Gods will shine down on us, as they always do.  Simply connect the outside siren to the delayed relay and this will only chirp the peizo.  It will have to see 1 solid second before the outside siren would begin to sound.  I will continue looking for the diagram, it consists simply of a relay a capacitor across 85 and 86 and a resistor in series with the feed wire of the coil.
