The L.O.C.PRO ADVANCED™ can be used to add amplifiers to an audio system that
does not have RCA outputs or when replacing an OEM radio and retaining the
factory amplified system. Variable Gain Controls with Clipping Indicators,
Selectable Ground Isolation and Load Select features ensure a pure, noise-free
signal for any type of audio system.
This Quick Start Guide will get you going, but if you need additional help or

Features & Wiring Information
Example Installation
Speaker level input from radio to RCA level output for an aftermarket
amplifier is the most commonly used configuration for the L.O.C.PRO ADVANCED.
This will create RCA-level outputs from a radio that only has speaker-level
outputs.
In the example below, the Positive(+) and Negative(-) wires of two speakers
are “tapped” and connected to the SPEAKER SIGNAL INPUTS of the LPA. The
speakers will continue to play as normal. The REM OUT has connected to the
amplifier’s turn-on. When the radio is turned on the LPA will automatically
turn on the amplifier. Lastly, the RCA SIGNAL OUTPUTS from the LPA are
connected to the aftermarket amplifiers’ inputs.
