I would like to build a surround system for my Garage where I hang out on a Saturday but don't wish to disturb my neighbors too much and also don't wish to spend a lot of money. I don't know much about surround sound except that when you are inside the area of the speakers, they sound very loud and when you step out of the area you hardly hear anything, this is basically what I want to achieve. So I will need a Sub for the Floor and 4 [or more?]speakers for the wall and a receiver? What I am thinking right now is how to get the "specs" for the equipment I need, my 1-car Garage is 20'Lx10'Wx8'H. Can anyone guide me or send me on the right track to figuring out just what it is I will be needing, how much power, specs of all of the equipment and placement of speakers e.t.c? How is this all done please? Thanks.
