2.4.2 Making loudspeaker connections (IZA 250-LZ)
Note: Loudspeaker connections are the same for the ZA 250-LZ amplifier.
1. Attach included crimp-on spade lug connectors to loudspeaker wiring. Blue spade lug connectors are compatible with
16-14 AWG wire. Red spade lug connectors are compatible with 22-16 AWG wire.
Note: You may need to bend the spade lugs to fit.
2. Make a single loudspeaker connection or connect two loudspeakers in parallel. When connecting the loudspeakers
in parallel:
i. Connect the wires from the amplifier to the matching positive (+) and negative (–) terminals on the first loudspeaker.
ii. Connect the positive (+) and negative (–) terminals of the first loudspeaker to the positive (+) and negative (–)
terminals of the second loudspeaker.
Caution: Do not connect more than two loudspeakers together in this manner. Doing so could damage the amplifier.
