Installation
6. Prepare the REM turn-on wire for connection to the amplifier by stripping 1/2" of insulation
from the wire end. Insert the bared wire into the REM terminal and tighten the set screw to
secure the cable into place. Connect the other end of the REM wire to a switched 12 volt
positive source. The switched voltage is usually taken from the source unit's accessory lead.
If the source unit does not have this output available, the recommended solution is to wire a
mechanical switch in line with a 12 volt source to activate the amplifier.
7. Securely mount the amplifier to the vehicle or amp rack. Be careful not to mount the
amplifier on cardboard or plastic panels. Doing so may enable the screws to pull out from
the panel due to road vibration or sudden vehicle stops.
8. Connect the source signal to the amplifier by plugging the RCA cables/high level inputs into
the input jacks at the amplifier.
9. Connect the speakers. Strip the speaker wires 1/2" and insert into the speaker terminal
and tighten the set screw to secure into place. Be sure to maintain proper speaker polarity.
DO NOT chassis ground any of the speaker leads as unstable operation may result.
10. Perform a final check of the completed system wiring to ensure that all connections are
accurate. Check all power and ground connections for frayed wires and loose connections
which could cause problems.
NOTE: Follow the diagrams for proper signal polarity.
CAUTION: These amplifiers are not recommended for impedance loads below
2Ω stereo and/or 4Ω bridged (mono).

CAUTION: Use only one input
configuration. Using both
the RCA and High Level
inputs will cause
undesirable operation.

*NOTE: When using High Level Inputs, if audible engine noise is present, connect the Black wire
to chassis ground. If noise is still present, contact your local authorized dealer or
Lightning Audio customer service.
