subwoofer huming

skky

Hi guys I recently bought a submersive that started humming as soon as I plug it into a wall outlet.The thing is if I plug it into a surge protector,the huming is minimal to the point of me having to push my ears to it to hear anything.When I plug it into the wall outlet,the huming will increase/decrease with the gain button.I tried posting on the seatonforum but it's hard getting any input there even through email.

Is this a hum I should worry about?Could it be a defective amp?I can't even use my sub right now because I'm worried,any input would be great guys.You think the support would be better when your paying that much for a sub-(

Try using a cheater plug at the end of the sub's power cord. If it has a two-prong, use a three-prong cheater. If it has a three-prong, use a two-prong cheater.

thanks george,I will have to grab one as soon as the ice storm settles down lol.In the meanwhile you think I should be able to use the sub or no?

Does it hum with the signal interconnect cable/s removed?
Is it plugged into the same AC wall outlet as the rest of the system?

No the humming is totally gone with the cable removed BUT while the cable is connected,changing from the powerbar to the wall outlet will cause the humming to get louder.I'm just worry that is can affect/damage the amp somehow.

Do you have any signal cables from cable TV or satellite TV or internet or audio systems in other rooms connected?

If all else fails:
