Tell us about how you have the knobs on the back of the sub set, and how you have the receiver setup as far as crossover and speaker settings small/large?

The LFE from the sub will be much more common during movies with lots of LFE. My guess is the song's your listening to don't have those low signals often.

For starters put the volume on the back of the sub to about 11 o'clock position, turn the crossover knob all the way clockwise to get it out of the way for the reciever to manage.

Check the receiver's setup menu to make sure your starting will all speakers set to small and a crossover of 80hz.

I'm not familiar with using an Ipod or other MP3 player, so can't comment on LFE signals. Have you tried a movie that has good LFE?
