set lpf to 80 hz, set subsonic filter as low as it can go (probably 15hz)

No, if his box tuning is 35hz the subsonic filter needs to be at or just below
35hz.

Subsonic filters prevent over-excursion in ported boxes by eliminating frequencies below box tuning.

Infrasonic is another name for subsonic filter.

If theres no adjustment on the amp its pre-set at a frequency the amp maker chose.

Probably at 20-25hz, but you would have to look in your manual to find out what it is.

i just looked through the book and it says engaged at 28htz so i guessing nothin below that is going to be played if i have it on.. So turn the cross over to 32?? wat about the knob crossover is that the same as the other one and should be at 32 too

With a ported box tuned to 35hz you should leave the infrasonic filter in the on position, its there to keep notes too low for your sub to play from damaging it.

The crossover should be set to blend the sub with your front speakers, usually 60-80hz with 6.5" speakers up front, or 80-100hz with 5.25" speakers up front.

The correct crossover point is whatever sounds like the best blend with you front speakers to you.
