There is a complicated proper way to set the gain. Using a special CD that plays certain freqs and voltmeters.
Then there is the easy way.
-Turn GAIN all the way down
-Turn HU volume to 3/4 full
-Play a familiar track on CD or radio
-Turn up gains until the speakers start to clip
-Turn gain down a notch, right before it clips.
Done.
As for the EQ...:dunno:
