LPH Harness Instruction Guide

Important Notes

All LPH harnesses are designed to work on OEM Non-Amplified systems.

All LPH harnesses are designed to be modular and used in various applications. (Listed Below)

If no powered accessories are going to be installed behind your radio, you will not need to use the LPH-SPK(F) pigtail. If you are using this harness, make sure your loose ends are connected prior to plugging into the main LPH harness. If not connected to a device or insulated, this could cause a short circuit.

Example Installations

Mono Amplifier - LPH-SPK(E)

Description: This section illustrates connecting the LPH-SPK(E) harness to split either the front or rear channels of the main LPH harness. This provides a high-level output suitable for devices like amplifiers, DSPs, or LOCs that accept high-level input signals. The LPH-SPK(F) can be used to provide power, ground, and accessory connections for the audio adapter.

Diagram showing the LPH-SPK(E) harness connecting between the OEM radio connection and the LPH to OEM harness, with the LPH-SPK(E) splitting the signal to an amplifier. An LPH-SPK(F) pigtail is also shown connected for power/ground/accessory.

Multi-Channel Amplifier - LPH-SPK(A/B/C/D)

Description: This example shows how to split front and/or rear channels on the main LPH harness and insert LPH-SPK(A-D) in between. Harnesses LPH-SPK(C) and LPH-SPK(D) provide a high-level output for devices like amplifiers, DSPs, or LOCs. Harnesses LPH-SPK(A) and LPH-SPK(B) allow the output of an aftermarket amplifier to be routed back through the factory wiring.
