(POWER 

CONNECTION) 

   remote

Connects to the positive terminal of the battery. 

 

Connects to sw12 V from the source unit.

For specified performance 4 Ga cable is required.

Fuses shall be placed within 8” / 20 cm of the battery. 

        

GND (REMOTE) 

      

Connects to the vehichle’s chassis. 

Keep as short as possible (< 20” / 50 cm).

Use minimum 4 Ga cable for optimal conditions.

We recommend to use  minumum10 Ga speaker cables to acquire the intended performance.

Run the speaker cables from your speakers to the amplifier’s mounting location. 

Ensure these are ran separately and away from high current cables and if possible the RCA cables as well. 

In all cases where cables are penetrating the vechile’s chassis use grommets to protect the cable. 

Connect the speaker wires according to the terminals on the speaker(s). 

Strip 3/8’’ / 1 cm of insulation of the end of each cable and twist the cable strands together tightly. 

Make sure there are no stray strands that could touch other cables or terminals as it can cause a short circut. 

Crimp spade plugs over the end of the cable or tin the ends with solder to provide a solid terminal.

Connect the cable ends to the amplifier as shown in the diagram.     

        

      

      

 

 

 

 

CAUTION

 

        

Installation of the amplifier shall be done in the following steps:

1. Connect the +12V wire, keep in mind this wire has to be fused at the battery as well. 2. Ensure the ground is 

appropriate, then connect it to the amplifier. 3. Connect the switched remote. 4. Reattach negative wire (ground) 

to the battery. 5. Operation over 15V  will cause the amplifier to go into protect & can void the warranty!
