when i got this amp I tested the wattage and it only puts out 612.50 max 306.25 rms On a single dual voice coil wired at 4 ohm 12 bridged.
I had to wire it to 4 ohms because at 2 it kept blowing the amp fuse within 30sec to a min of playing music . On the other hand I can run it between 30 mins – 2 hrs everyday and it hasn’t overheated so seem to be reliable it’s just really underrated
