cp-25 wiring question

can anyone tell me the correct way to wire a pair of cp-25s? wire terminals are numbered 1 and 2. The first speaker was no problem 1 hot 1 ground, but now ready to add the second speaker and not sure of the wiring order. Thanks .
 
Wire them in exact parallel. One wire from the siren/PA should go to terminal 1 on BOTH speakers, and the other wire to terminal 2 on both.

Wiring one of the siren wires to terminal 1 on one speaker and terminal 2 on the other is known as wiring "out-of-phase" and negatively affects operation as well as being hard on the output electronics of the siren.
