This 7 Channel DSP controlled amplifier can be found in all variants of Mazda MX5 from 2009 onwards. It has a maximum power output of 240 Watts - located behind the drivers seat  , it's slightly time consuming to remove. 

It's worth noting that the Bluetooth kit runs through the amplifier - so the amplifier is 'on' the minute the door is opened regardless of the radio being on/off. 

What Fails and Why 

After spending many hours reverse engineering this unit we have built up an extensive knowledge base on the circuit. We have improved the design and have developed a 'repair/reliability' kit which we fit on all units. This enables us to confidently supply a lifetime warranty on all repairs.

There are no known faults with the headunit - all issues are with the amplifier. 
Common symptoms are ; 
  • No Sound Machine gun noise through speakers 
  • Loud white noise 
  • Battery drain 
  • Random loud noise when door is opened 
Models Covered  
  • NH61 66 920 or NH6166920 - 
  • NH60 66 920 or NH6066920 - 
  • NH58 66 920 or NH5866920 -
