I just bought a Massive NX4 to replace an old Precision Power PPI-3050. Very nice looking amp, slight problem though, the NX4 is heavily distorting when trying to produce any kind of bass. I discovered that with any one of the rear RCAs removed, it'll put out some decent bass, but as soon as I reconnect the other cable it goes to crap. The amp is just powering two Infinity Kappa 6x9s in the rear and two Polk 5 1/4s in the front, so I'm not asking miracles from it or anything.
Is this a defective amp, or am I missing something? The PPI would pump out enough bass to rattle the trunk lid, not so much with the twice-as-powerful NX4...
