OK - so the Alarm has a NEG(-) Out to trigger the siren ... that's normal.

Try this ... test the SIREN by just touching its wires to the cars battery ... the thing should scream, since the siren is new, right?

If it doesn't, bad siren. If the siren screams, gotta go back to testing the Alarm & the Install. Since the siren needs +12V & a Ground to operate, lets test those wires out by the Siren. First, is the wire that's SUPPOSED to be +12V REALLY +12V?? Test it with a DMM. If not, Correct & Test. If it IS +12V, time to test the Alarm's (-) Siren Output - again, with a DMM. If the ground is poor, check the ALARMS GROUND AGAIN! Correct & Test.

Virtually all weak-sounding Sirens trace back to 2 things:

1) Poor Ground someplace.

2) Water in the Siren. !!!

Ok, Here is the new proble. I did volt test on wire comiung from brain to siren. It is constant hot. When alarm is activated is goes cold. The other wires seem to be fine. Also the wire tests at 11.9 volts, not quite 12. Any sugesstions? You guys are really a big help, Thanks
