Patent ID: 8213631

Claim:
A sound system, comprising: a power source; a head unit powered by said power source, said head unit configured for generating an electrical signal; a relay in communication with said head unit and configured for receiving an electrical signal generated by said head unit, wherein said relay has a first output so as to direct an electrical signal therefrom, and wherein said relay has a second output so as to direct an electrical signal therefrom; a first speaker in communication with said relay, wherein said first speaker is configured for receiving an electrical signal from said first output of said relay; a second speaker in communication with said relay, wherein said second speaker is configured for receiving an electrical signal from said second output of said relay; a switch configured to be opened and closed in order to trip said relay between a first state in which said relay is configured to direct an electrical signal from said first output to said first speaker and a second state in which said relay is configured to direct an electrical signal from said second output to said second speaker; a second relay in communication with said head unit and configured for receiving an electrical signal generated by said head unit, wherein said second relay has a first output so as to direct an electrical signal therefrom, and wherein said second relay has a second output so as to direct an electrical signal therefrom; a third speaker in communication with said second relay, wherein said third speaker is configured for receiving an electrical signal from said first output of said second relay; and a fourth speaker in communication with said second relay, wherein said fourth speaker is configured for receiving an electrical signal from said second output of said second relay; wherein said second relay is configured to be tripped upon opening and closing of said switch between a first state in which said second relay is configured to direct an electrical signal from said first output of said second relay to said third speaker and a second state in which said second relay is configured to direct an electrical signal from said second output of said second relay to said fourth speaker; wherein in one position of said switch both said first relay and said second relay are in the first state and in another position of said switch both said first relay and said second relay are in the second state.
