Self tuning should be a fairly easy process. First, find a song you know well. It needs to have a good range of sound... highs, mid and bass. Set all your EQ settings on the radio flat. Find out what is the range of your volume knob on the stereo. For instance 1-10, 1-100 or whatever. Find the max and set it a 75%. If it goes from 1-100 set it at 75. Then unplug all your RCA's except for one. Lets says it ends up being the in cabin speakers. Get your song playing and turn the volume on the radio to your 75% setting. The slowly adjust the gain until you hear the speakers distort. Then adjust the gain down. Unplug that RCA and to the next. Repeat this until all have been set. Then fine tune your treble and base.
Some guys your 75% and I have seen some use 80%. Either is a good set point. Anything higher than that can add distortion from the radio that will feed into the amp.
fantastic! thanks for the info as I will give this a try this weekend and post my results!
