No, duong, your "feel" isn't correct. The 320 has plenty of power and bass response essentially flat to 20hz; any bass problems have nothing to do with the amps involved. You may be demanding too much bass; you shouldn't actually hear the sub as a separate source. If the EP350 is right in the corner, it's getting the most bass reinforcement from the room. If you have to have more, turn up the bass level on the sub and/or the receiver. I assume that you have the crossover on the EP350 turned all the way up.
