Multi Channel Amplifiers
•
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 chassis, sand all the paint away from the contact point. A
grounding block like the Street Wires GT4 should be used whenever possible
as this piece of equipment has 5 times the surface area of a normal screw.
The gauge of the power and ground wire is often an overlooked aspect
of amplifier installation. The more power the amplifier receives, the more
power it will produce. power cables have a natural resistance, and will lose
voltage by the time the power makes its way to the amplifier. The large
gauge diameter wire will hold more voltage over longer runs. Also, by having
a larger diameter ground wire, the amplifier can run more efficiently. it
recommends using a minimum of 4 gauge power and ground cables to get
the best performance.
double check all the previous connection installation steps, in particular the
speaker and power wiring. securely mount the amplifier. if everything is in order,
reconnect the vehicle’s negative battery connection and begin following the
Feature setup and Adjustments steps.
