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.

LPH TO RADIO CONNECTION
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 Amplier, 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.
