alright on the side of my amp i have 2 nobs taht say HPF and LPF and i can adjusst them by turning the nobs, there is also a switch, you can have the switch pointing to one of 3 things: HPF LPF or FULL, i keep it on full bc thats what it was one hwen i got it, but i found that when it is on HPF it is a lot louder and deeper, what does HPF and LPF mean? and would it be bad to keep it on HPF? would taht mess anything up?
