Quick question may be veeman can answer for me you mentioned in a previous post on how to adjust the amp that the cross over settings could be played with abit what does the crossover setting actually do for the sound or the amp
Thank you for all suggestions you guys offered when doing this

Crossover cuts of frequencies. if you set your LPF at 100 hz, it will cut off (by cut off i mean will not reproduce) anything above 100hz.
different types of speakers are ment to reproduce different frequencies, hence why crossovers are used.
For example, bigger subwoofers are generally ment to reproduce the low end frequencies, 25 to 100 hz. Then you have mid bass speakers in forms of smaller subwoofers which can reproduce anything from 125 to 250. And so on, the smaller the speaker the higher the frequency it will reproduce best. Tweeters are tiny and they play in the range of 5k+ hz. This is very general but that's how it goes.
So to answer your question, the crossover doesnt really do anything for the amp itself. It is there to help you reproduce the proper frequencies thru your speakers.
If your amp has a LOW PASS FILTER, it will cut off all frequencies ABOVE whatever you set it at.
If your amp has a HIGH PASS FILTER, it will cut off all frequencies BELOW whatever you set it at.
If you are using a 2 or 4 channel amp it should have both of those.
A single channel amp (mono block) normally would not have a high pass filter. It would have a subsonic filter instead.
