My guess is the sub is too hot and you need to turn down the gain on it. As the others have mentioned you need an SPL meter and set the system up with all speakers to the same level, using the pink noise from the receiver or some test tone cd's/dvd/s like Avia. You can then adjust the sub up from there as most of us seem to run the sub a little hot by 2-5db.
