dual siren wiring?

if anyone has a link to anothe post on this,,please hook me up,,i looked but could not fid any other posts..thanks & i apologize for the potential double posting.. whats up..i finally finished the install of an alpine sec8052 alarm,on an 02 passat wagon. i have a second alpine siren i want to hook up,but im not quite sure the best method.. i figure a relay is needed.since the alarm might not be able to preduce the amps to juice 2 sirens...thats cool...it wont be much different that wiring up foglights.. i have an extra armed output wire (- 200ma)..can i use this to throw a relay to juice a 2nd siren? "who would have thought that it would have left such a big hole...."

ive hooked up 2 sirens to alpine alarms with no problems at all, if you wanted to use a relay you could, 85 to ground, 86 to the siren wire coming from the alarm, 30 to +12v, 87 to the siren + input
