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.
Wiring Connection Chart (All Models)
LPH-SPK (E) Can be use in both front or
rear configurations based on user preference.
LPH-SPK (F) Not all vehicles will provide accessory signal (Red Wire).
Example 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.
Example Installation – Multi-Channel Amplifier – LPH-SPK(A/B/C/D)
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.
