ADAPTER’S terminal block on the adapter. Be sure to connect the car audio’s
system (+) wiring to the terminal block (+) and the (-) car audio system to the (-)
terminal block for each the LEFT (L) and RIGHT (R). Plug the HIGH LEVEL-IN wire
adapter into the amplifier. Set the AS selector switch (item 8) to the “HI” position.
2. Power Terminals - Please take proper measures during installation to protect
the power wires as best you can. For example, when running the power
cable from the vehicle’s battery through the firewall, use a firewall bushing
for protection. Run the power wire through the interior of the vehicle, under
the carpet, and to the amplifier. If this is something that you do not feel
comfortable doing, please ask a professional to help you. Be sure to lay the
power wire away from all signal cables.
• +12V (Item 3): This is the main power input for the amplifier and must be
connected directly to the positive terminal of the car battery for the amplifier
to operate properly. It is important that a main fuse is installed a maximum of
8” from the battery.

• REM (Item 4): This connection turns the amplifier on and off. REM
connection is used based upon the amplifier input source (high level or low
level) and if the source unit has current sensing technology.
Low level input: Use the REM connection if the amplifier is connected to the
low level inputs (RCA). Connect the REM to the source unit’s remote-turn-on
output. If the source unit does not have a remote-turn-on circuit the amplifier
can be connected to +12V using a switch powered from the ignition switched
circuit.
High level input: Determine if the vehicle’s source unit has current sensing
technology. If the source unit does have current sensing technology then REM
is not required to turn on the amplifier.
If the vehicle’s source unit does not have current sensing technology while
using the high level source input then connect the REM the same method as
the low level input.
• GND (Item 5): This is the ground connection for the amplifier and must
be connected directly to the metal chassis of the vehicle for the amplifier to
operate properly. A properly grounded amplifier can be run harder and longer
than a poorly grounded amplifier. The ground on the amplifier should be as
short as possible and be connected directly to the vehicle’s metal chassis. Do
not connect to factory bolts of ANY kind. When attaching the ground to the
