hey guys. i need some opinions on whats good to do in my position. i gotta power 2 9" tvs, a 400 watt continuous inverter (for the xbox) and a 280 watt max amp for a sub. should i just run everything off the battery? i know the amp and power inverter prolly will have to be run off of the battery. but could i just use a 12 v power wire to run the tv's off? or what would yall suggest??? thanks
