Controls & Connection Locations

Front Panel Controls:

Diagram shows front panel controls: LPF (Low Pass Filter) knob with frequency settings (50Hz, 250Hz), X-OVER switch (LPF, FULL), LEVEL knob (MIN to MAX), LOW INPUT RCA connectors (Left and Right), and HIGH INPUT terminals.

LPF (Low Pass Filter): Adjustable from 50Hz to 250Hz.
X-OVER: Selectable between LPF (Low Pass Filter) and FULL (Full Range).
LEVEL: Adjusts the amplifier's input sensitivity, variable from 200mV to 6V. This is not a volume control.
LOW INPUT: RCA connectors for signal cables from a source unit.
HIGH INPUT: Terminals for speaker-level inputs.

Rear/Side Panel Connections:

Diagram shows rear/side panel connections: Fuse holder, Power indicator LED, GND (Chassis Ground) terminal, +12V OUT (Battery Positive) terminal, Speaker terminals (+/-), and Remote (Rem) terminal.

Fuse: Protects the amplifier.
Power: Green LED indicator that illuminates when the amplifier is turned ON.
GND (Chassis ground): Connect to a clean, bare metal surface of the vehicle's chassis to avoid ignition noise.
+12V (Battery positive): Connect directly to the positive (+) terminal of the battery. Install an in-line fuse holder (not included) close to the battery.
Rem (Remote Turn-On Input): Connect to the remote turn-on wire of the head unit. The amplifier turns ON when the head unit is turned ON.
Speaker: Terminals for connecting the speaker(s).

Wiring

Signal Input Connection Mode:

Please Note: Use either Low Input or High Input, not both simultaneously.

Wiring diagram illustrating signal input modes. Low Input uses RCA cables from the Head Unit. High Input uses speaker wires from the Head Unit, color-coded for Left (Purple/Green) and Right (White/Blue) channels.

Low Input: Connect RCA cables from the Head Unit's pre-out jacks to the amplifier's LOW INPUT RCA connectors (Left OUT, Right OUT).

High Input: Connect speaker wires from the Head Unit's speaker outputs to the amplifier's HIGH INPUT terminals. Use the provided harness. Connect Purple/Green wires to the Left channel inputs and White/Blue wires to the Right channel inputs.

Power Input & Output Connection Mode

Power Input & Output Connection Mode diagram. Shows battery connections (Black to GND, Red to +12V), Orange Remote Out wire, and Speaker connection (White/Black wire to speaker).

Battery Connection: Connect the Black wire from the amplifier to the vehicle's chassis ground (GND). Connect the Red wire from the amplifier to the vehicle's battery positive (+) terminal. Ensure an inline fuse is installed on the positive wire near the battery.
Remote Turn-On: Connect the Orange wire from the amplifier to the Head Unit's remote turn-on output wire.
Speaker Connection: Connect the White/Black wire from the amplifier to the speaker. This amplifier is designed for 4 Ohm speakers only.

Troubleshooting

SYMPTOM	CHECK POINT	CURE
NO SOUND.	Is the power LED illuminated?	Check fuses in amplifier. Ensure Turn-on lead is connected. Check signal leads. Check gain control. Check Tuner/Deck volume level. Clean contacts on fuse holders.
	Is the Overload LED illuminated?	Check for speaker short or amplifier overheating.
AMP NOT SWITCHING ON.	No power to power wire.	Repair power wire or connections.
	No power to remote wire with Head Unit on.	Check connections to radio.
	Fuse broken.	Replace Fuse.
NO SOUND IN ONE CHANNEL.	Check Speaker Leads.	Inspect for short circuit. Check for open Connection. Check Speaker Leads Reverse Left and Right RCA inputs to determine if it is occurring before the amp.
AMP TURNING OFF AT MED/HIGH VOLUME.	Check Speaker load impedance.	Inspect that speaker load impedance recommendations are followed. Check wiring configuration for speakers. (To verify proper load impedance, use an OHM meter to measure the total load for each channel of the amplifier.)
SYSTEM PROTECTION LED IS LIT	Temperature Shut-down.	Check for proper air ventilation. Change amplifier location.
	output shorted.	Check speaker wiring. Check for blown speaker by disconnecting one at a time and check for LED change.
