Re: How should I set the Gain, LP Filter, Subsonic, on my Alpine MRX-M100 with 1 SWR1
Someone touched on this but it needs to be reiterated... gain setting has nothing whatever to do with the subwoofer you're using. It is there to match the preamp signal of your head unit to the input sensitivity of your amplifier. At 2 volts of preamp signal your gain should probably be at about 12 o'clock but there is no way to say that for sure without a scope or distortion detector.
And you're right, setting gains properly is complicated to some degree but what you have to decide is whether or not proper gain setting is more complicated than earning the money to buy a new subwoofer and then going through the trouble of removing the blown subwoofer and replacing it. For my money and time, proper gain setting is a breeze relative to that alternative. ;-)
As for the other settings, you should never use bass boost unless you listen to music that has very little bass. Where you have it set now is just adding to the clipping you've caused with the gain being set too high. Your other settings are fine where you have them.
