Interconnect cable checklist:
Level control checklist:
Refer to the section "setting up systems after in stall ation for best performance"
Mlnmum ftnalloudspeaker Impedances: ·2 ohm per channel in stero mode
·4 ohm mono bridged.
-We need to feed the same signal to both sets of channels, so must use 2
Mono bass woofer wiring
-Connect the mono speaker positive terminal to the RIGHT +, and its negaitive terminal to LEFT
Switch setting checklist:
•1/2CH
•3/4CH
Crossover frequency control checklist: channels 1/2
·HIGH PASS: 100 Hz
•HIGH PASS (subsonic!: 20 Hz
•Low PASS: 100 Hz
Please note that these frequency points only. Refer to the

2way active, or
Here we present a variation of the previous system. Since this is a 2 way system, wecan use the front outputs from a head unit to drive the highs, and the rear output to drive the bass This method allows the listener to easily adjust the relative levels of bass to highs, with the front to rear fade on the head unit. Channels 1 anf 2 will be used for highs, and channels 3 and 4 for mono bass.
interconnect cable checklist:
-Use good quality RCA leads to connect the inputs of the amplifier to the source as shown.
-Follow the instructions as per the previous system for switch and crossover settings.
