Hey I installed a crimeguard 745i3 alarm in my Eclipse and recently a friend of mine gave me an extra siren. I tried wiring the siren directly with the one I already had and just grounding it but it wont chirp like its supposed to. Now tneither siren works until the alarm is triggered. I was thinking that I may need a relay to help power the second siren but does anyone know how to wire two or more sirens to an alram? Thanks in advance.
