Connect stereo RCA outputs (L/R or SUB OUT)
of the head unit with INPUT (L/R) of the amplifier
INTERCONNECTION
• Connect the RCA outputs of the head unit with the RCA jacks INPUT (L /R) of the amplifier with appropriate high-value RCA cables
by using the included wire harness.
If a separate SUB OUT from your head unit is available, use this as line output.
• Connect the subwoofer with the SPEAKER OUTPUTS by using the included wire harness.
• Always ensure that the total impedance load 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.
FILTER SETTINGS & BASS BOOST CONTROLLER
• The cut-off frequency is adjustable with the LOW PASS controller and should be set between 60 to 100 Hz, depending on the
size of the subwoofer. The SUB SONIC controller eliminates the ultra-low, not audible frequencies to generate a bandpass
signal. 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 LOW PASS setting, no sound is audible.
• The BASS BOOST controller allows a bass enhancement up to +18 dB.
LEVEL CONTROLLER
• Turn the LEVEL INPUT controller of the amplifier to the MIN position.
• Turn the volume controller of the head unit 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 REMOTE
• The enclosed BASS REMOTE CONTROLLER adjusts the bass-level e.g. from the driver's seat.
Please use only the enclosed bass remote controller and cable.
NOTE
Do not connect loudspeaker cables with the vehicle's chassis. Always ensure the correct polarity of all connections.
