I want to add another siren or two to my alarm because it is not loud enough. my question is that when i add one or two more siren will i need to hook a relay to them and how many amps should i fuse the relay too? this is the siren i was lookin at https://www.partsexpress.com/pe/showdetl.cfm?&DID=7&Partnumber=330-090 what u guys think. should i add one or 2 more?

When ever you use more then 1 siren you must add a relay . Each siren pulls about 2.5 amps.

one or two just makes it louder and louder, most people that i've seen that do that usually put one inside under the dash (if they're trying to cut the alarm out this will atleast give them a hell of a head ache, and two under the hood, i'd put a relay with about a 10 amp fuse on it for 3, it's a little high, but it should do just fine,
