Hello
I used this amp for 5 years.
for me it is a very good reliable product which may have counted.
in terms of quality for me are amps that lack of punch for the boxes but still very clear to the heads.
the power level it's just they do hardly even see the power announced a can of below especially for a sub of below 80HZ.
In conclusion, it is rather an amp for the sound of SNV reliable power but not compared to the crest or Amcron
GETTING STARTED I refairais this problem without NIOHC
