Dont use your iPod as the source. Use the PS3. There is probably a setting on the iPod that is causing problems. The PS3 is a much better source to use anyways. So you are getting bass now but is there still unwanted noises such as humming or anything else that sounds strange such as distortion?

I’m armed and I’m drinking. You don’t want to listen to advice from me, amigo.
