Hi all, new user and have a little question, i have a fusion 12" subwoofer in a 44litre sealed box, it sounds good but doesnt go very loud, its powere by a 240w RMS power module, now should this box be ported? and will i get a different sound if the subwoofer faces the other direction? also on my pre amp i have a switch that says 0 or 180, its the frequency of the sin wave, can someone tell me what this does and what it shoud be set to?
Thankyou
