Do not connect loudspeaker cables with the vehicle chassis.

Always ensure the correct polarity of all connections.

REFERENCE NOTE

INTERCONNECTION EXAMPLE 1-Channel Mode: 1x Mono Subwoofer bridged

Use the bass enhancement with care.

A high bass boost may cause damage to your speakers and hearing abilities.

INTERCONNECTION

• Connect the RCA lineouts of the headunit with the RCA jacks LINE INPUT of the amplifier with appropriate high-value RCA cables.

If your headunit is equipped with a additional subwoofer lineout (SUB OUT), it is recommended to use this lineout.

• Connect the subwoofer with the speaker outputs (SPEAKER OUTPUT + BRIDGED -) by using appropriate wires.

• Ensure by any means, that the total impedance load of the channel-pair is not lower than 4 ohms. Too low impedance cause high

temperature and will shut down the amplifier operation.

• Always ensure the correct polarity of the speakers. The interchange of plus and minus cause total loss of bass playback and could

damage the speakers.

CROSSOVER SETTINGS

• In the mono/subwoofer mode the X-OVER switch must set to the LP/BP position (Lowpass/Bandpass mode), thereby the higher

frequencies will be eliminated. The cut-off frequency ist adjustable with the LOW PASS controller and should be set between

60 to 100 Hz, depending on the size of the subwoofer.

• In the lowpass mode (LP/BP) the HIGH PASS controller works also as subsonicfilter, that eliminates the ultra-low, not hearable and

harmful frequencies to generate a bandpass signal (Bandpass mode). The subsonic frequency should be set between 15 to 40 Hz,

depending on the size of the subwoofer. NOTE: If this value is higher than the lowpass setting, no sound is hearable.

LEVEL CONTROLLER

• Turn the LEVEL INPUT controller of the amplifier to the 4V position.

• Turn the volume controller of the headunit to 80 - 90% of its full setting.

• Turn the LEVEL INPUT controller clockwise until you hear some distortion.

• Then turn back the LEVEL INPUT controller slightly until you hear a cleaner sound.

BASS BOOST CONTROLLER

• The BASS BOOST controller adjusts the bass enhancement between 0db and +12dB.

• A too high bass boost may cause clipping/distortion and damage on the loudspeakers and also may harm your hearing abilities.

Use this controller carefully!

BASS REMOTE

• The enclosed BASS REMOTE Controller adjusts the bass-level e.g. from the driver’s seat.

Please use only this enclosed bass remote controller and cable.
