BRIDGED BRIDGED BATT REM GND CH1 CH2 CH3 CH4 FUSE LEFT SPEAKER OR SUB-WOOFER 4-8 OHMS RIGHT SPEAKER OR SUB-WOOFER 4-8 OHMS 2-CHANNEL MONO (BRIDGED) OUTPUT WIRING DIAGRAM USE #10 GAUGE WIRE (SEE TEXT) Power Indicator Lamps After initial set-up, the amplifier should not require any further adjustment unless there is a change in the car stereo or speaker system with which it is used. If activated by a rise in emperature, the unit will resume operation after cooling off to a normal operating range. If activated by an overload condition, the source of the overload must be found and corrected to resume operation of the amplifier. Most overload conditions are caused by mis-wiring or operation into incorrect speaker loads. Re-check all wiring and connections if this situation occurs and correct as necessary. 2 1 312 5 7 OPERATION GNDGND 2CH2CH 1CH1CH 3CH3CH 4CH4CH XOVERX OVER 50Hz50Hz 250Hz250Hz 250Hz250HzMINMIN MAXMAX PP 50Hz50Hz PPGAINGAIN MINMIN MAXMAX GAINGAIN LPFLPFFULLFULL XOVERX OVER HI-INPUHI-INPU LPFLPFFULLFULL PWRPWR PRTPRT 2CH2CH4CH4CH 1CH1CH3CH3CH REMREMBATTBATT GNDGNDBRIDGEDBRIDGED BRIDGEDBRIDGED CH1 CH2 CH3 CH4 FUEFU E 4 6 The Power Indicator Lamps will light to indicate that the unit is connected to the battery and that the Remote Turn-On terminal is receiving +12 volts, thus turning on the amplifier.
