subwoofer boxes

[Montana00]

No i heard alot of good stuff about hifonics amps.

Heres a question for anyone who can answer. On my Amp i have a bunch of volume controls. All of them are maxed except for two.

Low Pass and SubSonic are set at half. Should i leave those at half or should i raise it. Because i want to get the most out of my subs, but i dont want to blow them.
