Hey, Just picked up a pair of Speakers for a 5.1 audio system. Model is LG Sb94sa March 2009. I Tried looking everywhere for these and can't find a single thing then whats listed on the sticker on the speakers. Center, fronts and back say 4ohm 450w (program) max power. Sub is 3ohm 8inch. Im looking to put these inside my racing trailer. I need a simple and cheap Receiver with for use with my ipod and radio. Nothing special Can anyone steer me in the right direction for these speakers?
