Re: Matching Subwoofer with Amplifier
Your gain should be set to match the preamp voltage of your head unit. That is what it is designed to do and it doesn't matter what size, how many or what power rating your subs are. As for bass boost, the best setting for it is OFF. ;-)
It would help to know what head unit you have and what the specs are of the box the sub is in. Otherwise no one can really offer you and useful advice.
