The main speakers are places like I would do with normal left and right. It sounds good. But then the subwoofer moves the image with not playing only low frequencies. It's a 4ohm, very cheap shit but gets the job done. It doesn't matter where they are sitting. If they are both connected to only the right channel, then you only have the right channel playing......which is not stereo sound, which means your imaging is going to be nonexistent by default as "imaging" requires more than one source signal (i.e. left and right). The simple solution here is to buy a plate amp or another amplifier to power your subwoofer. It may not be what you want to do, but it is what you need to do. I don't really care about left and right anymore. I am not a big fan of home audio and that's why I am not investing anything into amplifiers and what not. I just don't want my subwoofer to play anything else than low frequencies. If it means I have to invest money into another amp I would not care if there are birds singing in the right channel and a streaming river in the left channel. When it comes to car audio, then it is whole 'nother story. It is not what I am looking for when It comes to good sound, but as I said not a big fan of HA. Let my put it that way- it sounds fairly well for only one channel.
