Okay, I THINK that's it now. It took a lot of fiddling.

I'm watching Batman Returns later so we'll see how that sounds.

hope your doing well buddy!
Doing quite well indeed!!!!

Hmm...it was okay. I buzzed like the speaker at the beginning of Back to the Future the whole time and infrequently crackled like tearing paper, and sometimes things that should really have bass did have bass.

Maybe it's time for a new sub.

you might have a ground loop hum. This happens when the frequency wave of power in the receiver and the frequency wave on the sub are not in sync. Long story short is has to do with the outlets you are getting power from and then the cross connect of the copper cable between the sub and the receiver. you may want to look for a ground loop hum filter or eliminator. Some of them plug into the wall and then you plug the sub into the isolator, others plug inline with the RCA cable between the receiver and the sub. You may want to give that a try as it is far less expensive then replacing a sub. Also you may want to replace the simple stereo wire that you are using with an RCA/Coaxial cable. You don't need a super expensive one but these coaxial/RCA (Sub woofer cables) are usually a smaller gauge wire (means the copper is actually thicker for better electrical flow) and many times these RCA/Coaxial cables are also shielded which eliminates interference from other wires that are running next to them.

three things you haven't told us:

how long have you had the sub and was it new or used when you got it?

was the receiver you have new or used?

if you replaced your previous receiver with the one you have pictured and if you were using the sub you mention, did the same thing happen then and how did you have it connected?

I'm daring to gather without knowing you didn't have this (or a) sub before or you would have just hooked it up like you would have had the previous one.

answering these questions and giving as much data as possible helps us to give you better recommendations. we still are kinda guessing on some of the facts.

we are here to help buddy.

Sounds like you have a possible bad driver or a bad amp.

It was brand new when I bought it in 2002. But since day one it had always thumped when a nearby electrical thing was switched on.

Light goes on - THUMP!

Text message - THUMP!

Switching the woofer on itself - THUMP!
