I had the desire to listen to my favourite music on weekends during the summer months on my covered porch,back yard with a beverage,BBQ and family and friends.The desire came when next door,the neighbours son moved in a few years ago,settled in and then started annoying me by playing loud the hip hop,rap ,gangster rap crap almost every night and weekends.The desire became a need and to solve the problem I put together this system,but since I brought my music outdoors with this system the problem vanished.!!!!
