Question about MA Audio HK4000D Car Audio Amplifier
If there is no protection light on, be sure the input is on. Some head units need to be turned on manually (factory set to OFF).
Verify the subwoofers are wired properly.
A list of your components would help to solve your problem.
If it is new, it should still be under warranty - worst case scenario output transistor(s) blown, or power supply bad.

Audiobahn subs are not too powerful and they can not handle too much continuous RMS, be careful they will heat up and tear off the voice coils off ur subs. run about 100 - 150 RMS at 75 HZ to each sub and keep the gains at about 3/4 this way you will avoid blowing out your subs. It also depends on the amp? What kind of amp is it?
Let me know if you wish. Otherwise
