That Aura amp used to be mine. It is an older “Cheater” Amp. 4ch/3ch/2ch Bridgeable.  
Class A/B  
Unregulated Power Supply.  
100RMS X4 @4 Ohm @14.4V  
200RMS X4 @2 Ohm @14.4V  
400RMS X4 @1 Ohm @14.4V

I had this amp and those MTX subs in my S4 at one point in time and hit 143Db at S/R cruise night. In the right car they could easily do over 145Db clean.
