How to make Audio Source broadcast audio in all directions? [2D]

Hey! I was wondering if there is a way of making my audio source play the sound like "360" around itself. I have a ship with canons on both sides which all fire simultaniously. But couse my audio source has a side in which it plays the sound i guess (not sure about this) it plays the sound diferently depending on how my ship is turned. So if my ship is turned left it plays the sound very strongly on the right speaker and the other way around as well.

I guess one solution would be to make 2 audio sources, 1 for each side of the ship but that seems far from ideal to me.

Thanks for any answers in advance guyz!
