I just installed the clifford RSX 3.5. I think the siren isn't as loud as i want it to be. I'm wondering if I could add or replace the siren with a louder one. Is there anything special about this siren? Will a different siren work the same as this one?

You need to add a relay first to add second siren-------

87 to two sirens

30 to 12V power

85 to ground

86 to alarm system siren output

Alarm unit siren output is not strong to drive 2 sirens.

If you are only replacing with deferent siren you don't need the relay.
