I just picked up another pair of Insignia outdoor speakers from BB ( I had a gift card to burn). I am thinking of hooking them up to add sound to an area of the yard a little further out than my patio, probably 40-50 feet total distance from the reciever. To do this I can't really have the speaker wire laying above ground so I thought well the wire is protected could'nt I just dig a small trench a couple of inches down and bury the wire??

Any thoughts??????
