Security, adding a second siren?

[stewster61]

OK, i have the python 881XP alarm system/remote start on my car and it is great definetly one of the best alarms i could of bought. But it isnt loud enough, so i ordered a second siren for it, my question is how do i install the second siren, i kno i can't just splice into the other siren, and ive heard that the wires have to be the same exact length, is this true? Can someone help me out? Thanx!!!

wire length does not matter.. add a relay

might want to think about this. i installed a second siren once. it's one of those ideas that sounds good on paper, but doesn't work out so well in the field. my 2 sirens never did get the timing exactly right, one would start and the other would start. it was only a split second difference, but you could still tell there were 2 different sounds coming out. got on my nerves, so i took it out.

it made the alarm louder, dont get me wrong, but it wasn't as loud as i had hoped.

but to answer part of your question, wire length shouldn't matter, and i dont remember how my 2nd siren was hooked up

That's actually a good thing that they start at different times... makes more of a ruckus when it goes off.

I have at least 3 sirens on my car.. Use a relay to power all your extras with the original siren wire as the trigger.
