Abstract

A combination speaker and amplifier unit has speaker located on the front of a cabinet and speaker wire receptacles located in the back of the cabinet for providing speaker wire connections to a stereo unit. Also in the back of the cabinet is a power booster amplifier mounted thereon for amplifying the left and right stereo signals provided by the stereo unit. A power cable extends out the base of the power booster amplifier which is mounted to a cut-out section of the back of the cabinet so as to place the power booster amplifier within the cabinet, The power cable has a cigarette lighter adapter plug allowing the power booster amplifier to by powered by the power supplied to the cigarette lighter socket of an automobile.
