Check loudspeaker wiring
This product contains a biamp. It is important not to connect the front
loudspeaker ground to the rear speaker ground.
Faulty loudspeaker
Distortion at highest volume levels may be normal, as amplifier has reached
maximum power output. Otherwise the power and ground wire might be too
small of a gauge. Use 10amp cable or more.
Reduce the bass effect or switch off the loudness mode
