my new xtant a600 amp has a crossover and the lowest you can go on it is 40 hz. what if i wanted a lower fq cus my box is tuned to 33hz? also the low filter goes all the way down to 20hz that doesnt make sense?
ok here goes. If you go lower that 40 hz you will not hear most of the bass in many songs. Put it at like 120hz ish for low pass id your pushing subs wich i think you are. Your box is tuned to 33 hz so you want to turn your subsonic filter up to 33 hz so you dont blow your subs.
