INTERCONNECTION
• Connect the RCA lineouts of the headunit with the RCA jacks LINE INPUT of the amplifier with appropriate high-value RCA cables. If a
separate SUB OUT from your headunit is available, use this for the LINE INPUT CH3/4 on the amplifier.
• Connect the speakers with SPEAKER OUTPUT + CH 1 - and + CH 2 - and the subwoofer with the SPEAKER OUTPUT CH3/4
+ BRIDGED - of the amplifier.
• Ensure by any means, that the total impedance load of all speakers per channelpair (CH1 & CH2) is not lower than 2 ohms and the total
impedance load of the subwoofer (CH3 & CH4) is not lower than 4 ohms. Too low impedance cause high temperature and will shut down
the amplifier operation.
