Hey guys, took my XFL15s out of my car because they started sounding like crap, IDK why. Very muddy. So now Im kinda getting interested in SQ. I have two SA12s laying around doing nothing so I put one in a sealed box 1.2 cu ft and it sounds pretty good. I have it wired at 4 ohms on my MB Quart ONX2000 so about 650w before rise. The bass sounds awesome and tight but its very weak... I know coming down from 2 ported 15s to 1 sealed 12 is going to be a change but its almost inaudible on some songs. I was wondering if i should wire this one D2 to 1 ohm on my amp, about 1700w maybe before rise or should I put both of my sa12s in sealed and run them at 2 ohms at about 1300w before rise.
