CONNECTING THE AMPLIFIER

 1.

 Select cable and fuse according to the following table.

 2. 

Connect the amplifiers ground cable to a close, bare metal part of the frame or chassis.  Use a 

nut and bolt, NOT a screw!  The ground cable must be at least the same size as the +12volt cable.

  3. 

Connect  the  remote  terminal  to  remote  output  of  the  head  unit  using  16  gauge  (or  heavier) 

wire.

 4. 

Connect the fuse holder within 18”(45cm) of the car battery, and run the selected cable from 

this fuse to the amplifier. 

 5. 

Connect all the inputs with high-quality cables. Connect Remote Control if necessary.

 6. 

Insert fuse(s) into the battery fuse holder(s).
