ok well i ditched the whole idea of wall plugin and all that stuff but thanks for the suggestion audio guru. today was my last day in my electronics course anyways so i cant really get my hand on parts easy BUT. Ive gotten this far.....: the amp is originally designed to run on 12 volts DC but it also is able for some reason to run off my 9 volt battery and you can boost the soudn WAY U THERE like pretty loud. now i would like to know how long that battery might last cause i know not very long but what are we talking about here? hours of play? minutes? days?
