So you had another amp in there before that "wasn't bloated in the bass", correct?.
Assuming a swap out from your other amp to the Panny, and all things set relatively the same, I'd assume you're panny isn't so strong to control whatever speakers you're running, probably full range no doubt, yes?
If it's not bass modal problems from your set up/room, I'd say you have a lack of power, or too much bass level gain. I'd want to know measurements at certain frequencies in relation to 1Khz, compared to other amp setup you were using, to define "bloated bass" a bit more.
You need to do trial and error. Check the trebble and bass boost setting to make sure, as with dynamic range settings, EQ's etc. Also, subwoofer and crossover settings if applicable, the works. Really, there's only so many variables if your rig was set up correctly in the first place(i.e, flat frequency response overall).good luck
