1. Disconnect speakers.
2. Turn your gain/input sensetivity all the way down. Turn off bass boost and any crossovers.
3. Turn on your head unit. Set the volume control to 3/4 of full. Set all equalization and bass/treble controls to zero. Turn off loudness and BBE processing.
4. Probe your amplifier's outputs.
5. Insert your tone CD. Select a tone within your amplifier's playing range.
6. Play your selected tone and adjust the gain until you reach your target voltage.
7. Reconnect your speakers and verify proper operation. Set crossovers and adjust levels for proper tonal balance.


so when it says to "probe amplifier outputs" does that jsut mean probe the + and - on the amp? just stick the red and black cords inside the + and - connectors ?

Ignore their voltage table and use the voltage you calculated for your amp.

Just make sure EVERYTHING on your HU is off or at 0, and that your sub level is all the way up, and HU volume at 3/4.

People often forget something and and then can't set their gain right......
