Start with everything turned down. Turn up your LPF (low pass) to around 60hz. Set your Subsonic filter (if you have one) to around 15-20hz.

Power on the amp and play some music. Slowly turn up your gains listening for anything unusual. Since you haven't listed your head unit type/model, I can't advise you on what amount of voltage it puts out, to set your gains to. Usually I tune by ear, and rarely have to go above 1/3 - 1/2 way. Most amps will begin to have slight distortion when driven over 50-70% gain, so keep it below that if possible.
