If so, it would send more power if I only used two speakers? Thanks!
I just looked at the specs for the harman kardon 3770 and it says 120w per channel, two channels driven @ 6-8ohms. So I would think it would be lower if you add another pair of speakers. I don't think it would be a 50/50 split though. Most receivers the power is diminished when you add more speakers unless you are dealing with higher end equipment. For example, NAD typically has a rating that says all channels driven.
