AmpPRO can provide a pure digital audio output for use with ampliers or audio processors equipped with a TOSLINK input.

NOTE: The factory amplier must be unplugged or removed when installing AP4-FD31. The included harness provides connections for adding an aftermarket amplier to the factory-installed speakers.
