PAC LPH-SPK OEM Non Amplified System
The LPH Harness is a modular harness designed to work on OEM Non-Amplified systems. It can be used for various applications such as adding multi-channel amplifiers, standalone subwoofers, and providing power/ground/ACC.
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.
- 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 in to the main LPH harness. If not connected to a device or insulated this could cause a short circuit.

Product Usage Instructions
Adding Multi-Channel Amplifiers Front/Rear
- Split either the front or rear channels on the main LPH harness.
- Insert the LPH-SPK(A/B/C/D) in between.
- For standalone subwoofers, use LPH-SPK(E).
- Make sure all loose ends are connected prior to plugging in to the main LPH harness. If not connected to a device or insulated this could cause a short circuit.
Provides Power/Ground/ACC
- Use LPH-SPK(F) for providing power, ground, and ACC for your audio adapter.
- If no powered accessories are going to be installed behind yourradio you will not need to use the LPH-SPK(F) pigtail.
- Make sure all loose ends are connected prior to plugging in to the main LPH harness. If not connected to a device or insulated this could cause a short circuit.
Example Installation – Mono Amplifier – LPH-SPK(E)
- Split either the front or rear channels on the main LPH harness.
- Insert the LPH-SPK(E) in between.
- This will provide a High-Level output for various devices such as an Amplifier, DSP, or LOC that can accept a high-level input signal.
- Make sure all loose ends are connected prior to plugging in to the main LPH harness. If not connected to a device or insulated this could cause a short circuit.
- You will want to test your vehicles factory speaker signal to verify that low level frequencies are present.
- This example will also maintain your factory speaker connection as it is bypassed though the harness.
Note: LPH-SPK(E) can be used in both front or rear configurations based on user preference. LPH-SPK(F) may not be available in all vehicles.

Installation
Mono Amplifier – LPH-SPK(E)
- For this application you will want to split either the front or rear channels on the main LPH harness and insert (LPH-SPK(E)) in between. (See Photo).
- This will provide a High-Level output for various devices such as an Amplifier, DSP, or LOC that can accept a high-level input signal.
- LPH-SPK(F) can be used to provide Power, Ground, and in some cases Acc for your audio adapter (See Photo Bottom Right)
- You will want to test your vehicles factory speaker signal to verify that low level frequencies are present.
- This example will also maintain your factory speaker connection as it is bypassed though the harness.
Installation Multi-Channel Amplifier
For this application you will want to split either the front and / or rear channels on the main LPH harness and insert LPH-SPK(A-D) in between. (See Photo
Harnesses LPH-SPK(C) and LPH-SPK (D) will provide a High-Level output for various devices such as an Amplifier, DSP, or LOC that can accept a high-level input signal.
Harnesses LPH-SPK(A) and LPH-SPK(B) will allow you to run the output of your new aftermarket amplifier back through you factory wiring.
