I have two single voice coil infinity kappa perfect 10s in a sealed box. The problem is that while on sub is ripping, the other is not, although it still has bass coming out of it. I thought at first that the + - connections were messed up, so I checked them, they were fine. But it did't stop, so I switched them on one sub anyways, and that sub turned into the dominant woofer. If anyone knows wtf is going on here please right me back. THNX!!!!
