Install instruction:

 

Just connet the wire to the amplified audio signal. Make sure to put falt aluminum on a plain surface. The sound,especially the bass sound will be generated by the resonance of the speaker and the surface, such as a wooden table.

 

Mace sure the flat aluminum panel face down in a vertical way.

 

Turn on the amplifier form small to large, and stop if you can get a good sound quality and low distortion. To avoid to load the amplifier to the maximum volume directly.
