Cautions:
• To prevent damage to your amplifier or autosound system, you must first
connect the ground, primary, and switched power wires (as described in
"Connecting Ground and Primary/Switched Power") before you connect the
speakers to the amplifier. Make the connections only in the order shown.
Damage to the amplifier is possible if you connect any wire incorrectly.
• Turn on the power to test the connections before you permanently mount
the amplifier (see "Testing the Power Connections").
• Be sure your speakers can handle 85 watts per channel, if you connect the
autosound system to two pairs of speakers (or 170 watts per channel if you
connect the autosound system to only one pair of speakers). Each speaker
must have an impedance of at least 4 ohms. Your local Radio Shack store
carries a full line of speakers to choose from.
CONNECTING GROUND AND PRIMARY/SWITCHED
POWER
1. To prevent damage to your amplifier or autosound system while making the
connections, disconnect the negative (–) cable from your vehicle's battery.
Note: After you complete the connections and reconnect the battery wire,
you will need to reset all clock/timer/memory devices in your vehicle.
