GND +12V REM
Connections: A150.4D
GND: Connect to the metal part of the ve-
hicle’s body. Scrape away paint to ensure
a low resistance connection. Do not tin the
wire with solder.
+12V: Connect to the + terminal of the
vehicle’s battery. You MUST install a fuse
holder with a 60A fuse within 18” (45cm) of
the battery’s terminal to protect the power
wire and the car in case of a short circuit.
Do not tin the wire with solder.
LOW LEVEL INPUT: Connect these to the
RCA type outputs of an aftermarket head
unit or preamp adapter or the low level
output of a factory installed head unit.
OUTPUT: Connect to speakers with an
impedance of at least 2Ω. To bridge the
amplier channels, connect one speaker
to 1+ and 2- and connect the other speak-
er to 3+ and 4-. The minimum speaker
impedance in bridge mode is 4Ω. Do not
tin the wire with solder.
REM: Connect to the remote turn on circuit
of the head unit or the vehicle’s accessory
circuit. Alternately, use the offset or signal
sensing feature of the amplier. Signal
sensing works with the low and high level
inputs. Do not tin the wire with solder.
HIGH LEVEL INPUT: These can be connect-
ed to the outputs of the head unit or the
factory installed amplier intended to drive
speakers directly. Be sure to observe prop-
er polarity. DO NOT EXCEED 30Vp.
