1.  Speaker Output

 – Connect these wires to your speakers using 

the included water resistant harness. Speaker wire may then be 

crimped or soldered onto the bare leads. Use a decent sized wire 

gauge as this baby is powerful! 

 

2.  Power Input Te12V & Ground 

– Connect these wires 

to the +12V and Negative binding posts of the vehicle battery 

via one of two included harness options. You may use either the 

included water resistant harness, or the included harness kit to 

terminate your own custom-length water-resistant harness. Use 

quality insulated wiring of the recommended wire gauge, such as 

wire gauge 8 or thicker.

3.  Remote Power Input Wire 

–  This wire connects to the 12V 

remote trigger output of some head units and controls the on/off 

state of the amplifier. Alternatively, you can use the GTO™ feature 

of the amplifier so it will turn on when an speaker level signal is 

detected at the RCA inputs.

4.  Power LED - 

When the unit has been powered on, the LED will 

glow warmly red.

5.  Input Level - 

Use this switch to specify which type of signal input 

voltage type you are using - high is speaker level & low is the RCA 

line level
