Burn the tones to a cd. before this is done, remember to turn off all eq's (set eq to flat) and turn bass boost off (it should be off anyway)

1. turn all gains down... If you have your front amped, start there, if not amped, start there anyway...

2. Play the 1khz tone on repeat, turn the HU up until you hear a definite change in tone or sound.... back off.... note where you are at. Ok you now have the clipping point of the HU defined.

3. play the 1khz tone again on repeat and at the level you just found on the HU. Go to your mid/high amp and turn your GAIN up until to hear a defined change in the tone or sound.. back off slightly... done there...

If your front stage ISN'T amped skip #3

4. Play the 50hz tone on repeat, go to your sub amp and turn the gain up until to hear a defined change in sound, back off a little and you "should" be done...

your sub(s) should be low passed @ 80 and your comps(speakers) should be highpassed @ 80.

remember...

80hz and down=sub

anything above 80hz is for mids

80 and 80 are set it and forget it rules of thumb, which is why the high pass is going to be set at 80.
