OWC Platinum Series Installation Manual

Audio Interface Harness Adapter
Installation Guide
1. Ensure the car is OFF and locate the BOSE Amp or factory subwoofer in the trunk (see diagram
below), depending on the type of kit you ordered.
2. Use a medium sized flathead screwdriver to press in the latching clip & carefully disconnect the
connectors from the Bose Amp and/or Subwoofer that will attach to the harness adapter.
3. Plug the adapter into the corresponding connectors as appropriate. Also make any connections
between the adapter itself, if applicable.
4. Refer to the harness adapter's labeling and the diagram below to connect your audio equipment.
The Bose radio outputs low-level differential balanced signals (that go through the specifically
designed RCA connections of the harness adapter). Therefore, we recommend audio equipment that
has differential inputs, or RCA inputs capable of accepting preamp and speaker-level signals.
Otherwise, you may need to use an appropriate Line Output Converter to avoid sound quality issues.
▪
Speaker Wiring (if your adapter has it) is labeled with a speaker number, in reference to the diagram
below. Speaker wiring goes to the Output of your amplifier(s).
Note: Gray or Red wire connections are + (Positive). Black wire connections are - (Negative).
