Axiom Home Page Forums General Discussion Technical Questions Humming JBL subwoofer.

Shield - again, I said assuming a coaxial cable would be the shield, signal ground, signal return, that with hooks up to the part of the RCA that don't look like a boy-part.

ie: your cable, if you made it yourself would have the center pins connected at both ends and the other connected only at one end.

Someone get me a napkin and a pen.

I think I may get it (BTW, thanks for the help everybody - my friends and family all think I'm some sort of audio/video genius due to the knowledge I've absorbed here in the past year ). If I were to disconnect the RCA plug from one end of the coaxial cable and reconnect it (sans the outer layer of metal shielding) I would break the ground that exists on that line. The sub would then ground itself via the power cord and the humming should stop.
Any special tools needed to reconstruct the end of that cable?

I wanted to ask, "Help with my sister-in-law's humming box?", but I was afraid that might be crass.
Would of made it far too easy for you hooligans, anyway.

What?! Your s-i-l has a kazoo? Can I have one, too?

Oh, and the humming isn't caused by the Winnie-the-Pooh toy that I shook out from the port.

Maybe the humming is caused by the Tigger toy that still IS in there??? Wasn't he the one that liked to bounce?

Actually, after thinking about it, I don't think the interconnect is the problem. The humming persisted unchanged after I completely disconnected the sub from the receiver. I even moved it to a different area of the house - still humming.
Is there a safety issue with using a cheater plug long term? I REALLY don't want to burn my s-i-l's house down.

Not so much a fire hazard as a shock hazard... like if the owner of the Tigger toy pours a pitcher of iced tea into the port and starts doing the 115v mambo. Try the ground break, see if it solves the hum - tells you whether or not it's a ground issue, it could just be a noisy amplifier circuit, since it's not exactly a high-end piece of technology.

bigjohn,

I thought everything was BIG in Texas...so overkill would have been more the theme...10gauge 3"mag/ never mind a claymore would be better.

unfortunately, i dont have a 10 gauge.. i dont even know if they make them anymore?? my papaw used to have one when my dad was a little boy. he sold it a lot time ago.

he used to tell me stories about it. they had the 10 gauge mounted to the front of a 12 flat bottom boat. they would troll up the river channels and blow turkeys out of the trees that were roosting. papaw said that 10 gauge would rock that boat back in the water about 5 ft everytime they would fire it. now, that is WAY illegal now, but back then, it was out of necessity, they had to eat.

MMmmm, I thought we were bad in Louisiana. Riding in a boat blowing up turkeys......now there is a thought.
