I have 4 herdio speakers on the way that come with a Bluetooth amplifier two left outputs two right outputs

The room is an outdoor veranda with dimensions 36ft X 12ft and I’m planning on placing the 4 speakers in the corners of the veranda but not sure if I should place both lefts side by side and a rights side by side on the short sides or the long ends or in opposite corners! Perfect listening position etc isn’t important I just want the sound to be consistent both ends of the deck without having to have it high volume to be nice to the neighbours when it gets late!
