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 A

4 will shut off 30 seconds after no signal detected.
Installation: ADCT4 The 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.

Adjusting the ADCT4 for maximum performance: After completing all of the necessary connections, turn
the ADCT4 adjustment pots all of the way down by rotating them completely counter-clockwise. Now, turn
the stereo system on and adjust the main volume control on the stereo to approximately 3/4 maximum vol-
ume. Select one of the adjustment pots on the and turn it slowly clockwise until you notice audioADCT4
distortion and then stop. Turn the remaining pots to the same position as the previously adjusted pot. The
audio set-up of the ADCT4 is now complete and ready to be enjoyed.
