Yeah, I should have looked at my amps manual before posting. I was going off a theater sound installers advice, which he said to just use one channel of the amp to power the center, and when I searched that, it wasn’t an option.
I learned that I can run my MC352 in either parallel or mono, to power my center. My only concern is that when doing that, it cuts the impedance of the amp in half. So the amp would be 4 ohms and the speaker is 8, with 3 being the lowest.
