Connect RCA outputs (CH1/2
and CH3/4) of the head unit with
LINE INPUT (CH1/2 and CH3/4)
of the amplifier.

4 - 8 Ohm
X-Over-Switch (CH1/2 Subwoofer 1 & CH3/4 Subwoofer 2)
• By using the Mono/Subwoofer-mode, switch to the LP/BP-position (LOW PASS/BAND PASS), that the higher frequencies are
cut off. The cut-off frequency should be between 60Hz - 100Hz. Adjust the level with the LO PASS-controller. In LP/BP-Mode
the Highpass-controller (HI PASS) is working also as Subsonic-Filter. The Subsonic frequency should be between 15Hz - 40Hz,
depending on the size of the installed subwoofer.
Input Level (CH1/2 Subwoofer 1 & CH3/4 Subwoofer 2)
• Turn the LEVEL control of the amplifier to 6V position.
• Turn the head unit volume control to about 80 - 90% of its full setting.
• Turn the LEVEL control clockwise until you hear some distortion.
• Then turn back the LEVEL control slightly until you can hear a clean sound.
Bass EQ (CH1/2 Subwoofer 1 & CH3/4 Subwoofer 2)
• This Controller regulates the Bass Boost from 0 - 18 dB.
Caution!
Please use the Bass-EQ carefully. The additional boost may result in clipping or overload.
Bass Remote (CH3/4 Subwoofer 2)
• The provided Bass Remote regulates the Bass Level of CH3/4 from e.g. the driver's seat.

Speaker & RCA Connections
ZXi 4400 / ZXi 6400 / ZXi 9400
3-Channel-Mode 2 Mono Subwoofer bridged
RCA & Speaker wiring:
• Connect the LINE INPUT of the amplifier to the head unit line output with appropriate good quality RCA cables.
• Connect the speakers/subwoofer with appropriate wires to the terminal block (SPEAKER OUTPUT/ - CH1/2 - Mono b
and the subwoofer with CH3/4 - Mono b) of the amplifier.
• The minimum final subwoofer impedance must not be lower than 4 Ohms per channelpair. Too low speaker loads result in too
high heat dissipation and may cause the amplifier run into protection.
• Please observe correct speaker channels and polarity as printed by the speaker terminal
Caution!
Do not connect speaker (-) to the ground or vehicle's chassis.
