Installation Instructions
Line Output Converter (LOC) should be installed on a stereo’s speaker output wires
The
or the output wires on an OEM amplifier of up to 150 watts per channel. These wires
can be found behind the stereo in the dash, on the outside of an OEM amplifier, or on the
input terminals on the OEM speakers.
Wire color and function
The audio input wire colors are an EIA standard for car stereo applications as follows:
Yellow = battery +12v input
Black = ground input
Blue = remote +12v output the above power wires can be connected directly
to the amplifier being added
White = left front (+) input
White/Black = left front (-) input
Gray = right front (+) input
Gray/Black = right front (-) input
Black/White = reference ground (-) (reference ground optional if noise is present)
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 positive input wires of the LOC. The same goes for the negative audio
wires. Failure to do this will result in poor bass response and low quality audio.

The LOC is designed to convert (2) channels of speaker level audio into (2) channels of
line level audio. This allows for the installation of line level products such as amplifiers,
EQs and crossovers on systems that do not have RCA line level outputs. In addition this
device will also detect the presence of an audio signal and then generate a +12V output
that can be used to turn-on an aftermarket amplifier.
Features
150 watts maximum input
Input circuit corrects
Crossover distortion commonly found on other brands of LOCs
6:1 Step down with variable output
Gold flashed RCAs
Attractive and durable enclosure
Note: The LOC will shut off 60 seconds after no signal detected.
