To install a home theater system you first have to decide which room you will be installing it into and get the dimensions of the room. You can take those to your local electronics dealer and they will advise you as to how many speakers you will need and how far apart to place them. You will then need to choose a receiver. When you get your receiver and speakers home you will need to wire your speakers and mount them at the proper locations. All of the wires will be connected to the receiver. You can then connect your TV, DVD player, etc. to the receiver and it will funnel all of the sound into your room.
