The present invention discloses a wireless transmission device for surround sound stereo systems using a front mixer to mix the subwoofer signal of the main stereo system with the left and right surround signals into a 2-channel signal and transmit the signal by a radio frequency. After the subwoofer receives and decodes the signal, and the rear crossover separates the subwoofer signal and sends the subwoofer signal, left surround signal, and right surround signal respectively to the corresponding speakers for the playback, such arrangement provides a wireless signal transmission between the subwoofer and the main stereo system.
