Not really sure. But I can tell you that need to get some better mains! Poke around a little in the steam vent and you'll see that Bose isn't exactly favored around here. But that aside, you might be trying to demand too much from your sub. Your second suggestion sounds like a good idea, so give it a try. Also, if you really like listening to music LOUD, then I think you should start looking for new mains. Those lil 301s aren't going to satisfy your craving for full sound.
