So I just got in my 2 12" JLs and a boss 700x2 amp, now, I'm not going to lie, I know next to nothing about all this audio stuff, and when I first got everything wired up and good to go, i noticed that all i could hear was just pure bass until i turned the volume up a ways so i got back there again and found all the knobs on the side of the amp so i played around with them until i got it to sound... well... better, but i dont know if its right, so my question is on this amp there is a "level" setting, low pass, high pass, bass boost, low boost, and high boost settings, and i was curious and to how i should go about setting all of these, because for hte most part i've got all of them turned all the way down and know i can get a lot more pound out of them if i do it correctly, any help is appreciated.
