i bought some home theater seats and these came along with them. 2 of them actually. first of all i'm a total noob and i have no idea how to set this up and wire it. this is my receiver... yamaha RX-V861BL... i currently have a 7.1 speaker set up. my question is do i need to purchase an extra amplifier or receiver to set this up? or can i just wire it to my receiver or my sub? no ideaa what i'm doing. thanks guys.
