OEM RADIO HARNESS

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 Amplier, 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.
