These terminals are used to wire your subwoofer(s) to the amplifier.

To avoid unwanted ignition noise caused by ground loops, it is essential that the amplifier be grounded to 

a clean, bare, metal of the vehicle's chassis. This metal surface should be solid, strong and connected 

directly to the frame of the car.

Note: GROUND WIRE SHOULD NOT BE EXTENDED MORE THAN 3 FEET (1 METER)

Due to the power requirements of the amplifier, this connection should be made directly to the positive (+) 

terminal of the battery. For safety purposes, install an in-line fuse holder (not included) as close to the 

battery positive (+) terminal as possible with an ampere rating not to exceed the total value of fuses in the 

amplifier.
