hello everyone...i installed a 1 kicker l7 15in. with a kicker zx1000 amp. I also have a great pioneer flip out dash with all these tuning capabilities. Im not familiar with what frequency i should set my sub in the dash nor do i know what to tune the 3 knobs "gain" "boost" and "freq" on the amp. i broke the sub in so i should be able to wale it. what setting should i set for optimal sound. thanks ahead.
