POWER CONNECTIONS

CONNECTIONS

INPUT CONNECTIONS

It is important to have good quality power and ground connections. Remember, to complete 
an electrical circuit, the ground connection is just as important as the positive power 
connection. Before any power connections are made, disconnect the ground cable at the 

                                                                                 

 

When the power supply lead, memory backup lead or ground lead are extended use a 5mm²
(AWG5) or larger automotive grade cable which will withstand friction and heat to safe 

GND = Connect the proper gauge ground wire to the amplifier "GND" terminal. Locate the 
position on the chassis of the car to which the amplifier is to be grounded. The surface must 
be free from any paint or dirt. This can be accomplished with a small grinding bit, sand 
paper or wire wheel. NOTE: Do not ground the amplifier to the "frame of the car. The frame 
on most cars and trucks is not grounded to the chassis(body). Use Solder or a clamp ring to 
connect the ground wire. Pre-drill the prepped chassis to bolt the ground ring terminal with 
nut, bolt and lock washers. Insulate metal and connector with paint or silicon to prevent 
rust and oxidation. Silicon also works great to prevent nuts and bolts from working loose in 
a harsh environment of an automobile. Upon completion of the ground connection, grab 
wire or connector and confirm that it is a solid connection. To prevent engine noise, it is 

REM = Connect the remote wire (power antenna output) from the head unit to the remote 
turn-on wire of the amplifier. If the head unit is not equipped with a remote/antenna output, 
locate a wire that is controlled by the accessory position of the key. It is important to have 
the amplifier turn off with the radio or key. If the amplifier remains on, the result will most 

12V = Connect the proper gauge power wire to the amplifier "B+" terminal. Run wire to 
wards the fuse holder that is no greater then 0.5 meters from the battery. Remember, the 
fuse is to protect the safety of the car in the case of a short. Connect fuse holder to battery,

This amplifier will accept low level inputs only. Low level is the same as line level. The low 
level signal is carried through RCA cables. It is preferred to use low level inputs to the amplifier 
if the head unit is equipped with the low level outputs. If not, you can use a "high to low
