The ADCT4 is is designed to convert 4 channels of speaker level audio into 4 channels of line level audio
that can be used by OEM amplifiers. It can also be used with OEM radios to add aftermarket amplifiers;
the optional DC4-RCA harness is required. This device will also detect the presence of an audio signal and
then generate a +12V output (verified by an illuminated LED) that can be used to turn-on an aftermarket
amplifier.
Features & Specifications: : The ADCT4 is able to handle 80 watts per channel continuous input with-
out over heating. The input circuitry is designed to correct the crossover distortion commonly found on
standard  LOCs  while  providing  a  high  to  low  level  step  down  of  6:1.  Output  audio  level  is  infinitely
adjustable using the onboard, high quality potentiometers. The remote output or amplifier trigger is rated
at 500mA (+12V) and will easily handle an outboard relay if additional current is needed. The remote out-
put will trigger instantaneously when the 
ADCT4 detects a DC voltage on the white, left + audio input wire
above 5V or a very low audio signal. The

will shut off 30 seconds after no signal detected.
Installation: ADCT4The  should be installed on a stereo’s speaker output wires or the output wires on an
OEM amplifier of up to 80 watts per channel. These wires can be found behind the stereo in the dash, on
the output of an OEM amplifier, or on the input terminals on the OEM speakers.
Wire Color & Function: The audio input wire colors are an EIA standard for car stereo applications as 
follows: 
INPUT HARNESS:  POWER HARNESS: 
WHITE
= LEFT Front (+) Input       = BATTERY +12V InputYELLOW
WHITE/BLACK   = LEFT Front (-) Input GRAY = POWER (-) GROUND Input 
GRAY BLUE= RIGHT Front (+) Input    = REMOTE +12V Output
GRAY/BLACK  BLACK/WHITE = RIGHT Front (-) Input  = ReferenceGround(-)  
GREEN = LEFT Rear (+) Input   
GREEN/BLACK  = LEFT Rear (-) Input
PURPLE = RIGHT Rear (+) Input   
PURPLE/BLACK  = RIGHT Rear (-) Input
OUTPUT HARNESS: 
WHITE = LEFT Front (+) Input      
WHITE/BLACK   = LEFT Front (-) Input
GRAY   = RIGHT Front + Input   
GRAY/BLACK  = RIGHT Front (-) Input 
GREEN = LEFT Rear (+) Input   
GREEN/BLACK  = LEFT Rear (-) Input
PURPLE = RIGHT Rear (+) Input   
PURPLE/BLACK = RIGHT Rear (-) Input
See back of sheet for adjusting the ADCT4
for maximum performance
NOTE: Be  sure  that  all  audio  input  connections
are polarized or in phase with each other. That is,
the positive output wires from the audio source
need to be connected to the corresponding posi-
tive input wires of the 
ADCT4. The same goes for
the  negative  audio  wires.  Failure  to  do  this  will
result  in  poor  bass  response  and  low  quality
audio.
