Subwoofer Noise

[Ghost_Rider]

Hi Guys
New to the forum.
Im having difficulty in troubleshooting the buzzing noise from my Subwoofer.
If i switch  the amp of first , my sub gives off a buzzing noize. Is this normal. I have checked all the cable, power connection and checked if the cable is connectd to the correct Sub output on the amp. Any ideas??
