Home theater installation costs can vary greatly depending on the size and complexity of the system, as well as the type of equipment being installed. Generally speaking, a surround sound system will cost anywhere from $200 to $2,000 to install. Some important factors that will affect the overall price include the following: - The number of speakers being installed - Whether or not in-wall or in-ceiling speakers are being used - The complexity of the wiring and installation process - Whether or not a custom AV cabinet is needed

It can cost anywhere from $200 to $10,000 to install a surround sound system, depending on the quality of the equipment and the level of complexity of the installation. For example, adding wiring and speakers to a home theater can be a relatively simple process, while installing speakers in every room of a house can be much more complex and expensive.
