I was just wondering... I own a class D mono amp. I'm looking for the best SQL sub for my situation - then, suddently it dawned on me!!! Is a class D amp and an SQ or SQL sub NOT a good match. I mean, to be a musical sub, I would need an A/B amp, right? Please help me straighten this out in my head. If I'm gonna keep the class D, should I not even bother with SQ factors, or is that just wrong? Thanks, everyone.
