Abstract: An innovative, unique visual display for a powered car audio amplifier. The audio amplifier includes a transparent cover plate, preferably formed of methyl methacrylate, having a name or pattern etched or engraved in the undersurface of the cover plate. A black light or neon gas light tube surrounds an edge of the cover plate. The light produced from the black light or neon glass tube is transmitted through the cover plate and is collimated at the etched or engraved pattern in the cover plate. The pattern appears illuminated when the pattern is viewed through the cover plate without any visible source of light present. The light also appears to highlight the circuitry of the amplifier chassis located below the cover plate.

Abstract: A car amplifier has a housing for containing a circuit board retaining electronic components, and a cooling unit. The cooling unit draws heat away from heat generating elements which are mounted on the circuit board. The cooling unit has two heats sinks formed as first and second tunnels. The first tunnel has an arm that contacts the heat generating elements and draws heat therefrom. Each tunnel forms an interior passage and has open ends. Fins are located on the interior of the tunnels, so that heat is dissipated to the interior passages. A fan is mounted to one end of each tunnel to force air out from the passage of the first tunnel and draw the air back along through the passage of the second tunnel and to the exterior of the housing. The tunnels are separated by a peltier device, which has a cool side abutting the first tunnel and a hot side abutting the second tunnel. Hence, the cool side cools the first tunnel, while transferring heat to the second tunnel.
