Connect stereo RCA outputs (FL/FR or RL/RR) of
the head unit with INPUT L / R
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.
• Connect the speakers with the SPEAKER OUTPUTS by using the included wire harness.
• Always ensure that the total impedance load on the speaker outputs is not lower than 2 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
• When using bigger speakers (more than 20 cm) set the X-OVER switch to the FULL position (Full Range Signal).
• When using smaller speakers (8.7cm - 16 cm) set the X-OVER switch to the HP position (Highpass Mode) to avoid any damage
by lower frequencies on the speakers. The cut-off frequency is adjustable with the HIGH PASS controller and should be set between
60Hz to 150Hz, depending on the size of the speakers.
• The LOW PASS controller is not in use in this interconnecting example.
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 BOOST CONTROLLER
• The BASS BOOST controller must be turned to 0 dB position in this interconnecting example .
BASS REMOTE
• The enclosed BASS REMOTE CONTROLLER is not in use in this interconnecting example.
NOTE
Do not connect loudspeaker cables with the vehicle's chassis. Always ensure the correct polarity of all connections.
