Lexus / Toyota Amp PRO
Retention of SOS
(Safety Connect / Lexus Enform)
Technical Bulletin
Note: In some vehicles there will be multiple speakers on the front right output of the factory amplier
with only one speaker passing the SOS audio. If that is the case, it is important to use the exact speaker
output of the factory amp that corresponds to the speaker playing the SOS audio to connect to the front
right speaker output of the aftermarket amplier. If the front right dash speaker is the only speaker playing
the SOS audio and now only the door speakers are going to be used, it would be necessary to run the
aftermarket amplier's front right output to the front right dash speaker wires, then use the front right
speaker output from the Safety Connect Module to connect to the door speaker that needs to be powered
by the aftermarket amplier. Method 3 can be substituted for ease of SOS retention if desired. Refer to the
"Vehicle Connections" section on page 5 for vehicle specic information.
