To use AC power, use the AC power cord to connect your amplifier’s AC IN
jack to a standard wall outlet.
To use DC power, use the DC power cord to connect your amplifier’s DC 12V IN
jack to a vehicle’s 12V accessory socket.
Cautions:
• Your vehicle must have a negative ground electrical system. If you are not
sure of this, check with your vehicle dealer.
• Disconnect the AC power cord before you connect the DC power cord.
Likewise, disconnect the DC power cord before you connect the AC
power cord.
