Remote terminal ( REM )
For RCA cable signal input:
Connect the radio power antenna lead = remote
turn on/off from the car stereo to the amplifier
remote connection. This turns on the amplifier
whenever the car stereo is turned on. You can either
use the built in remote cable in the RCA cable itself
or use a separate cable.
Sometimes a small disturbance may enter the amp-
lifier coming from the remote voltage , through the
built in remote wire and into the RCA cable. Thus
we recommend to use a separate remote wire and
run the RCA lead separate from remote wire, power
cables and speaker cables.
If there is no remote voltage available from the
stereo, you must connect to the ignition key through
the radio or any accessories fuse.
When high level input is used the amplifier starts
automatically when your car stereo is switched on.

Low level Input Wiring
Inputs may be low level from the RCA output of the car
stereo or high level from the car stereo speaker output.
Low level = RCA is prefered for the best sound quality.
Important
Use either the low level or high level input, do not
use both at the same time.
Low level input
Use a pair of shielded stereo audio cables with RCA
type jack. Most trunk-mounted amplifiers need a
20 feet RCA cable (approximately 5 – 6 meters).
Connect to input socket CH1 / CH2 on S2.
Or R/ L on S1.
S4 has dual inputs
CH1 / CH2 / CH3 / CH4 Depending on your chosen
configuration you can use either two separate RCA
cables, or a single RCA cable together with an Y-
split to connect both inputs.
A cable up to AWG 14 (2,5
mm
) fits the amplifier remote

High Level Input wiring
For High Level input:
Most headunits are pre-installed from the car factory
and have no RCA output, in this case you can take
the signal from the speaker output instead.
Use either a separate remote cable or let the high
level signal automatically start the amplifier.
Connect left and right speaker wires coming from
the car stereo to the high level input as shown. You
must connect both plus and minus as the inputs
are balanced, connecting plus only gives lower
level and bad sound quality. By changing the pola-
rity of plus and minus, you can change the phase.
The HL connector wires match with DIN wiring color
codes. The car loom wiring may have different color
codes. When High Level inputs are used, the turn on
signal for the amplifier is taken from the high level
input, therefore no seperate remote wire is needed.
S1
Connect high-level L and R (summing inside):
Hi level input plug.
S2
Connect high-level CH1 and CH2 as below:
Hi level input plug.
S4
The four channel amplifier is connected likewise,
however it has four channels. You can feed two
channels from RCA and two channels using high
level input from rear speaker cables, or all channels
from high level input.
Hi level input plug.
Hi level input plug.
