well to add to my project i got my audio amp oc board and there was something wrong with it and it didnt work. i ended up going to radio shack and bought a 20 dollar pair of pc speakers. and i am using a big 12 volt energizer battery pack meant for a portable dvd player. it sounds amazing. pictures soon to come. i plan on swapping out the battery pack later for a 12 volt drill battery for easy of use and charging. i am so happy to get it done in time to be used in a re-enactment of the Vietnam war this weekend. idk what battle. since i only needed one speaker and it had 2 i just just one stay inside normal for added sound. kind looks like crap but when you put the back on no one will ever know.
