On hifonics, on one side of the gain knob is .2v, the other 9v. He means hes guessing it in the middle of those, being around 4v, not set with a dmm.you said the gain was at 4 volts? if i did the math right it should be at just over 38
No bass boost, Subsonic somewhere around 30-35 (not too far below your tuning), lowpass at around 60-80HZHows about Subsonic, Bass Boost and Lowpass adjustments? Long thread here, for a refresher: Single type-r in a ported box,2.0cu.ft.@35Hz,with a Hifonics bx1000d amp. Wondering about settings on the amp for this set-up.
