Installation
Speaker level input from a radio to RCA level output for an aftermarket amplifier is the
most commonly used configuration for the IOEM44. This will create RCA level outputs
from a radio that only has speaker level outputs.
Below, the 4 speaker outputs from the factory radio are disconnected from the speakers
and connected to the Speaker Signal Inputs of the LPA. The REM OUT is connected
to the amplifiers turn-on. When the radio is turned on the LPA will automatically turn on
the amplifier. The RCA Signal Outputs from the LPA are connected to the amplifiers
inputs. The speaker outputs from the aftermarket amplifier are then connected to the
speakers.
