Batboard

hello everyone.. i am new here and i am embarking on a task. i am taking a motorola aarmn4038 mic (from CDM 750) and building a PA system for my tow truck. I HAVE read all the boards about just using a CB and its PA function.. not as cost effective as one would think.. i am building from scratch just for the fact i have the truck and i can build it to conceal all electronics.. only thing visible is the mic and power switch.. i am also very aware of the legal matters revolving around this.

i will be posting more as it becomes availible as well as pics. if anyone else has input or ideas on how to complete this.. i am all ears..
