Kicker KEYLOC Manuel D'utilisation page 15

Optional Testing for Audio Source Clipping
Point with an Oscilloscope: This test will tell you
where to set the volume knob of the factory source
unit during the KEYLOC setup process. This can
be used instead of the previous process with the
voltmeter to tell you if the INPUT Level switch should
be in the HI or LO setting.
IMPORTANT: If the signal coming out of the
factory source unit is clipping, the KEYLOC
setup process will fail to correctly fix the
signal!
If you have an oscilloscope, use the method below
to get the best results on the first try. If you do not
have access to an oscilloscope, please go to Signal
Restoration on page 16.
NOTE: Don't do this test with the factory speakers
connected, and ensure the speaker leads are not
shorted together.
