Features & Wiring Information
Installation
Speaker level input from a radio to RCA level output for an aftermarket amplifier is the most commonly used configuration for the IOEM22 and IOEM24. This will create RCA level outputs from a radio that only has speaker level outputs.
Below, the Positive (+) and Negative (-) wires of two speakers are “tapped” and connected to the amplifiers turn-on/ When the radio is turned on. the LPA will continue to play as normal. The REM OUT is connected to the amplifiers turn-on. When the radio is turned on, the Converter will automatically turn on the amplifier. Lastly, the RCA Signal Outputs from the LPA are connected to the aftermarket amplifiers inputs.
