Trunk Mount Amplifier
(120-1971B)                Operation                  Faxback Doc. # 18180

TURNING ON THE AMPLIFIER

The amplifier automatically turns on whenever you turn on your autosound
system.  The POWER indicator lights when the amplifier is on.

Thermal Overload Protection

The amplifier's overload protection circuit automatically shuts down the
amplifier and the red overload PROTECTION indicator lights under the
following conditions:

    The amplifier is overheated.

    The speaker wires are shorted.

    The DC power output is shorted.

    The ground wire is open.

    The speakers' impedance is above or below the rated output impedance.

If this happens, turn off your autosound system, let the amplifier cool 
down.  Then before you restart, check to make sure the speaker wires are
not touching, the ground wire is properly connected to your vehicle's
chassis, and the speakers' impedance is 8 Ohms.

SETTING THE INPUT LEVEL CONTROL

LEVEL lets you adjust the level of audio signals that enter the amplifier.
For the best performance, follow these steps to adjust the input level.

1.  Turn LEVEL fully clockwise to MAX.

2.  Turn on your vehicle's ignition (if necessary), then turn on your 
    autosound system.  The amplifier turns on.

3.  Adjust the autosound system's volume control to a comfortable 
    listening level.

LISTENING SAFELY

To protect your hearing, follow these guidelines:

    Do not listen at extremely high volume levels.  Extended, high-volume
    listening can lead to permanent hearing loss.

    Always start by setting the volume to the lowest level possible before
    you begin listening, then gradually increase the volume as necessary.

    Once you set the volume, do not increase it.  Over a period of time, 
    your ears adapt to the volume level, so a volume level that does not
    cause discomfort might still damage your hearing.
