INTERCONNECTION
• Connect the RCA lineouts of the head unit with the RCA jacks LINE IN of the amplifier with appropriate high-value RCA cables.
• Connect the front and rear speakers with the speaker outputs (SPEAKER OUTPUT + L - and + R -).
• 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 20cm) set the X-OVER switch to the FULL position (Full Range Signal).
• When using smaller speakers (8.7cm - 16cm) 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 HP controller and should
be set between 60Hz to 150Hz, depending on the size of the speakers.
• The LP Controller is not in use in this interconnecting example.
LEVEL CONTROLLER
• Turn the LEVEL 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 controller clockwise until you hear some distortion.
• Then turn back the LEVEL 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 Level 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. The interchange
of plus and minus cause total loss of bass playback and could damage the speakers.
