My gaarge is 24x50. I am wanting to put some speakers in my ceiling because I need all of the room that I can get on walls and shelves. Any recommendations? I know very little about it. I mostly want to know where and how I should mount them. If I mount tem flush with the ceiling do I need to put a box behind them? What size and how many should I go with? I just want a loud clear sound, doesnt have to have that much bass. I need everything, from the speakers to the reciever so if you could recomend some good brands and models to look out for that would be great too. I know the questions are broad but any help is greatly appreciated. Thanks.
