The most of the alarm systems have a siren output + ,so you can hook you relay from there , or some times even you new siren . Actually I've a autopage alarm with one siren underneath the hood and another one inside the car , both are wiring on parallel and I didn't have problems .

good luck

Use a relay to power the second siren. The SIREN output of the Alpine system is limited in output amperage so becareful. You can either ground the DEI siren and use a relay to power the 12 volt or run 12 volts on the DEI siren and use a relay to ground the (-) of the siren, doesn't really matter.
