Hi,
Looking for a simple volume control for my subwoofer....its currently "Thumping"
The subwoofer on my Sony surround system failed,so i was gifted an active subwoofer my mate had not even opened never mind used. Some people, more £££ than .....
I was able to get sound to the sub but with a high hum(a google chk told me its normal for this particular sub), so not a wiring issue. I decided to bypass the control panel and just wire up direct to the speaker....worked fine,hum gone... just its a bit loud and with limited bass/sub adjustment on the amp im hoping i can do something like this.....
How to Build a Speaker Circuit with Adjustable Volume
The above uses a headphone jack which i would not use...just the potentiometer somewhere on the speaker cable.
Would this work? or should i be looking at something else.
Thx Jack

I don't think it's going to work great because you will add more resistance to the output and the load will be higher (it will increase/decrease the volume on the sub but its not something you should keep permanent) For the Hum you can make filters to minimize the hum.
