     Referring again to FIGS. 1 and 3 of the drawings, in certain motorcycle designs, each vertical windshield mount bar  40  of the windshield assembly  37  is fitted with a conventional, downwardly-extending mount strut  44 , having a strut slot  45  in the bottom portion thereof, which strut slots  45  are designed to receive conventional structural members (not illustrated) provided on the motorcycle frame (not illustrated) of the motorcycle  30  (FIG. 1) for removably attaching the windshield assembly  37  to the motorcycle  30 , according to the knowledge of those skilled in the art. Accordingly, the housing  2  is preferably bolted to the respective vertical windshield mount bars  40  using the windshield mount bolts  42  and the windshield mount nuts  42   a , as illustrated in FIG.  3  and the entire windshield assembly  37 , having the motorcycle audio system  1  mounted thereon, can be quickly and easily removed from the motorcycle  30 , as well as the player  12  and the attached speakers  26  and the radio antenna  21 , after unplugging the single wiring harness plug  46  from a power plug  54 , illustrated in FIG.  7  and extending from a battery (not illustrated) on the motorcycle  30 . This removable arrangement in mounting of the entire windshield assembly  37  facilitates maintenance and/or cleaning of the motorcycle  30  without detachment of the motorcycle audio system  1 , in an optimum manner. 
     It will be further appreciated by those skilled in the art from a consideration of FIG. 1 of the drawings, that the housing  2  and the speakers  26  of the motorcycle audio system  1  are typically located above the handlebars  31  and the speakers  26  are oriented upwardly toward a rider (not illustrated) seated on the motorcycle  30  to facilitate optimum acoustical characteristics behind the windshield  38 , when the spacing of the handlebars  31  allows such a speaker configuration. Alternatively, as heretofore described, in the case of narrow handlebars  31  and limited space above the handlebars  31 , the speakers  26  can be secured to the bottom of the housing  2 , at the optional speaker mount openings  29 , illustrated in FIGS. 3 and 4 of the drawings, as heretofore described. As in the case of conventional motorcycles, the handlebars  31  of the motorcycle  30  are typically secured to a conventional steering plate  32 , located forwardly of the gas tank  34  and the speedometer  35  (FIG.  1 ). The steering plate  32  is also typically attached to the front fork (not illustrated) of the motorcycle  30  by means of a steering plate bolt  33 , which facilitates steering of the motorcycle in conventional fashion. 
     As further illustrated in FIGS. 1-3 of the drawings, a storage pouch or container  47 , for containing tapes, compact discs and other accessories may be provided adjacent to the housing  2  and may be mounted to the housing top  8  (FIG. 5) of the housing  2  in any conventional manner, or unmounted, according to the knowledge of those skilled in the art. As illustrated in FIG. 3, the storage pouch  47  is preferably wedged-shaped in order to fit between the windshield  38  and the adjacent housing  2  of the motorcycle audio system  1  and may typically be fitted with a loop-pile closure  53 . 
     It will be further appreciated from a consideration of the drawings that the motorcycle audio system  1  of this invention is characterized by safety, convenience, flexibility and optimum performance, not only under circumstances where the motorcycle  30  is operating, but also when it is desired to maintain the motorcycle  30  or clean it. In the latter case, the entire windshield assembly  37  can be removed from the motorcycle after simply unplugging the wiring harness plug  46  from the power plug  54  (FIG.  7 ), as heretofore described, or the motorcycle audio system  1 , including the housing  2 , speakers  26 , radio antenna  21  and player  12  can be quickly and easily removed from the windshield assembly  37  as a single unit, by removing the four mount bolts  42  and corresponding windshield mount nuts  42   a  as illustrated in FIG.  3 . Furthermore, the addition of the motorcycle audio system  1  to the removable, breakaway windshield assembly  37  does not impede the breakaway feature in the event of an accident involving the motorcycle. 
     The motorcycle audio system  1  is further characterized by convenience and flexibility, in that the player  12  may include a conventional or specially-designed radio, a combination radio and compact disc player, or a combination radio, compact disc player and tape player, CB radio and the like, according to the knowledge of those skilled in the art. Furthermore, referring again to FIG. 1 of the drawings a primary safety feature is facilitated, in that the player  12  is easily viewed by the motorcycle operator at a glance, without the necessity of shifting the operator&#39;s position on the motorcycle. Moreover, as further illustrated in FIG. 6 of the drawings, the radio antenna  21  is ideally located on one of the housing mount brackets  3  for raising and lowering in order to operate the player  12  as a radio, as desired. Power from a battery provided on the motorcycle  30  is typically supplied through a switch to the player  12  through the power wiring harness  15 , as illustrated in FIG.  7 . Power is supplied directly from the battery to the optional power plug receptacle  17  and the memory circuits of the player  12 , through the receptacle wiring  18 . The player  12  connects to the speakers  26  through the speaker wiring  28 ; the radio antenna  21 , through the antenna wiring  23 ; and the headphone receptacle  55 , through the headphone wiring  56 , and the ground circuit  59 , respectively. The capacitors  57  allow a common ground headset or headphone (not illustrated) to be plugged into the headphone and be used with the floating ground stereo speaker output. 
     While the preferred embodiments of the invention have been described above, it will be recognized and understood that various modifications may be made in the invention and the appended claims are intended to cover all such modifications which may fall within the spirit and scope of the invention.
