I have a sherwood am/fm basic amplifier that is connected to 2 sony speakers. I can play the radio, my ipod, and my tv all from this with great sound. However when it comes to playing xbox the sound is terrible, like a muffled or even when the volume is on 1 the sound seems to overwhelming. I have the sound coming from the the tv from the headphone jack into a converter to RCA then into the amp. This makes it so whatever is playing on the tv plays through the speakers. Everything sounds good besides the xbox which is connceted to the tv via hdmi. Please help or if you need more info to help please ask!!!
