I have used crown amps for subs. They are ******* compared to behringers. They have the power but they just dont push subs right. I don't have equipment to measure to know exactly why there was such a big difference. I've also tested inukes vs EP4000 amps and the EP4000 just destroyed the inukes in bass performance. The behringer EP4000 has improperly documented dip switches so most people dont realize the real benefit from them. But the EP4000 is by far the best sub amp I've found (again, once the dip switches are set right).
The proper dipswitch setting is every dip switch to the right except 8 and 10 to the left. I've read the specs. I've seen the measurements of how the 6000 puts out more power than the 4000. It's doubtful you're getting near the power rating on your amp anyway. The EP4000 is my first choice for sub amps.
I have tested and sold off several crown amps. I currently own 2 EP4000's for 2 sub arrays, 2 buttkicker amps, 2 inuke dps's a 6000 and a 1000.
