may be its because the HU is not giving the speakers,the needed watts to make that sound.

Did you increased your HU volume and tested ?

Ok do this.

Connect only 2 channels from the HU to the amp and see. Then try the other 2 channels.

I suspect it might be a damaged RCA out of the HU. The RCAs on the HU are soldered directly to the PCB. Sometimes this solder is not well done and one poorly sodlered RCA will cause the noise in all 4 channels.

Do not connect the sub or any other speaker while testing. Lets just focus of the soruce of this noise.
