I was having the same issue and did the following. Dropped the EQ to +2 Set crossover at 80Hz Set front speakers to small. Set volume level at +3 on amp. Turned the gains on sub down until i could just hear it at low volume. Moved it around a few times but works best un front. EQ has 4 setup options and using 1 for music and 2 for movies.Bass levels are higher for movies.
