The “IGN” connection is designed to do the
following: the CL441dsp will only turn on when
+12V is present at this connection. Conversely,
the CL441dsp will shut off as soon as +12V is
removed from this connecton. We recommend
that you connect this wire to a 12 volt circuit in
the car that is only energized with the key in the
“Accessory” (ACC) or “Ignition” (IGN) positions.
Since the CL441dsp is designed to control the rest
of the aftermarket system’s turn-on and turn-off
functions, this will ensure that the audio system
will only operate with the key in ACC or IGN
positions. See “Signal Sense Modes” section on
Page 9 for further options.
The “REM.OUT” (Remote Output) connection
provides turn-on voltage to other aftermarket
equipment (just like an aftermarket head unit’s
remote turn-on lead).
FUSE REQUIREMENTS
The +12V constant wire on the CL441dsp
power harness has an inline 1 amp, fast blow AGC
(small glass-bodied) fuse for protection of the
unit. Do not remove this fuse or replace it with a
different value of fuse.
OUTPUT CONNECTIONS
Four RCA-type jacks provide four-channels
of analog audio output to feed your aftermarket
system. These are located next to the “Power
Connector” and are clearly labeled for each channel.
Think of them as your new head unit outputs.
POWER CONNECTIONS
Before installing the CL441dsp, disconnect the
negative (ground) wire from the vehicle’s battery.
This will prevent accidental damage to the system,
the vehicle and your body during installation.
The CL441dsp has a 4-pin inline jack located
next to the line output jacks. This jack accepts
the following connections (a wiring harness with a
mating plug is included):
“+12 V” : Co12V
“GND”:
Chassis Ground
“IGN”: Sw12V
“REM.OUT”:
Amplifier turn-on (+12V)
Since the CL441dsp does not draw very much
current during operation, 18 AWG - 16 AWG
wire is ample for making all of these connections.
Use good-quality crimp connectors (or solder and
heatshrink tubing) to join the harness leads to any
extended wires. Any wires run through metal
barriers (such as firewalls), must be protected with
a high quality rubber grommet to prevent damage
to the insulation of the wire. Failure to do so may
result in a dangerous short circuit.
Ideally, the “+12V” (constant) and “GND”
(chassis ground) connections should be run to
the same distribution points that the amplifiers
use for their power and ground connections. This
minimizes the possibility of noise in the system.
