    My twin 16-46CS subs both have a hum whenever they are turned on, I've tried a cheater plug, but it doesn't help. Any other suggestions??

    Try a different subwoofer cable.
    If that doesn't help...a GLE(ground loop eliminator)from RS might work---about $15.

    Plug the amp for the subs into an outlet which is on a different circuit breaker than the rest of your equipment. If the hum goes away, then it is ground loop hum. If not, then you have a different problem, like one with the subwoofer output from your receiver or pre/pro.

    Do you have cable? If so that may be the cause of the hum.

    I've tried going from one cheap cable to another, but I don't have anything that was more then 5$. I do have cable TV, does that have any effect?? Line Level Cables, Speaker Level Cables, refresh my memory on what the differences are. hehe.

    Your CATV coax can often inject a hum into your equipment.
    Turn the system on so that you can hear the hum, then un-screw the CATV coax from your system (TV, VCR, etc). Does the hum go away?
    If so, try this site for a solution:

    I found the problem, it wasn't cables, I had the ART 351 eq. stacked on top of the samson amp. I was moving it around and I found when I lifted it off of the amp, the hum would go away, and when I set it back down the hum returned. Kinda wierd, but I just moved the ART to another shelf and the hum is gone.

    Interesting....my ART 351 also made a hum so I flipped the ground lift switch in back and it went away. I have noticed the power supply in the ART can get audible when hot, I wonder if moving it will help....
