Hello 
I have 2 Elite 4 used to drive competitions. 
'm Disappointed of it because all have spoken well .. 
The Elite4 amplifier is not working properly. 
When the channel I in the frequency range of 40-125Hz at 18db I have an unassociated noise. 
It sounds like if a voice coil is broken. (As metal) 
I got it back and forth it tasted comes from the amplifier. 
I tried to switch the amplifier and the problem remains the same on an amplifier and channel. 
I have forwards as a Pioneer headunit P99RS of only the selected frequency. Oh Morgen you have the already written but never get an answer. 
There are 2 Elite 4 for sale. 
No help from ?????? 
It is not a SQ amp. 
 
  
My instalation.
