^ more info please
are you talking about an amp running your front soundstage or a sub amp? If its for your front soundstage, what kind of speakers do you have up front? Do you have a subwoofer?
Let us know and we can give our opinions, but there will be no wrong or right answer (and hopefully no unreasonable ones too!)

If your amp is powering a sub dont turn all your crossovers off! If you have both your deck and amp set to cut off at 50Hz (a little low IMO for music) it will just have a sharper cutoff point. For example instead of attenuating the signal at 12db/octave it will be (12+12) 24 db/octave. So a tone at 100Hz will be 24db quieter in comparison to 12db. If your amp was set at 80Hz then it would be around 16db quieter at 100Hz. Hope that wasnt to technical.

If you set your LP deck filter to 50 hz you are cutting off frequencies starting at 50hz and at the slope rate of your deck filter (probably 12 db/octave). If you set your amp LP filter at 50 hz with your deck filter still on you will effectively increase the slope to the combined slopes of the deck and amp, which means music above 50 hz will fade quickly out of the sub. Setting the amp LP filter at 80 would not do you much good as there is probably very little sound coming through at 80 with your deck filter already on.
Personally, I would try your amp filter set at 50 - 70 and then turn off the crossover altogether on the deck. If your amp crossover is fully variable, try all sorts of different cut-off points and listen to what sounds good and what sounds like the subs are taking too much power.
Good luck - those subs should sound great when set up properly.
