I usually play around with my cross over settings while listening to something with a lot of male and female vocals {Islands in the stream works well, I'm not crazy about the song lol, and country is one of my least favorite music genres, but Dolly and Kenny give the swing...}, and it has a bass note in there that lights the sub here and there...Anyway I play that song on the front 3, and change the crossover as I am doing this start at 60 and go up in steps and choose the best sound... I end up listening to that song 3 or 4 times but the end result is always good.... "Islands in the stream, that is what we are, no one in between, how can we be wrong, sail away with me to another world and we rely on each other ah ah" lol the only bad part is it gets in your head and you will never forget the song...
