Used for 2 months still works perfectly, upgraded to twice the power so don't need. This is perfect for normal and high volumes with clear sound, but at earplug levels it lasts for awhile then puts itself into protect (naturally because it's not rated for earplug specs).
rated at 83w per channel @ 2ohm.
Don't know what 4ohms is at but it's rated higher than specifications. Don't have birth certificate anymore but I know it's a 'good' one.
