well, first.. it helps if we know what kinda receiver you got? also, if you have a subwoofer?
a good general setting to start would be: WITH SUB- put all your settings to small, and the sub crossover at 80mhz. WITHOUT SUB-leave all your settings on large.
and then check your manual to do any additional tweaks from there.
but let us know what kind of receiver you got, that way, the people with those types of receivers can help you out a lot better.
EXCUSE ME, ARE YOU THE SINGING BUSH??
