PAC LPH-SPK OEM Non Amplified System Instruction Manual

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.

The following table shows the wire color and function for each-SPK model:

Product Usage Instructions

Adding Multi-Channel Amplifiers Front/Rear

1. Split either the front or rear channels on the main LPH harness.
2. Insert the LPH-SPK(A/B/C/D) in between.
3. For standalone subwoofers, use LPH-SPK(E).
4. 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

1. Use LPH-SPK(F) for providing power, ground, and ACC for your audio adapter.
2. If no powered accessories are going to be installed behind yourradio you will not need to use the LPH-SPK(F) pigtail.
3. 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)

1. Split either the front or rear channels on the main LPH harness.
2. Insert the LPH-SPK(E) in between.
3. 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.
4. 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.
5. You will want to test your vehicles factory speaker signal to verify that low level frequencies are present.
6. 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.
