I've been working hard to find a Professional to assist you with your question, but sometimes finding the right Professional can take a little longer than expected.
I wonder whether you're ok with continuing to wait for an answer. If you are, please let me know and I will continue my search. If not, feel free to let me know and I will cancel this question for you.
Please note, I am just a moderator for this category, I can only try and find experts to help, I can't answer the question itself.
I am happy to wait for an answer.

Still no reply yet. Is there a problem ?
Hello, I’m Nathan, and I’ll be assisting you today. My livelihood depends on your positive feedback, so your satisfaction is my highest priority.Sorry to hear you’re having trouble. You likely haven't received an answer because this is a somewhat unusual situation and chances are high that it cannot be resolved, due to a hardware problem.There are a few possible issues here, but placement and cleaning won't help unfortunately.This is either a hardware failure in the sub itself (shorted amp, bad power supply, bad crossover circuit, etc) or there is interference from an outside source. Given the frequency, I would expect this to be a motor/heater/compressor type load starting up and causing a blip in the power that interferes with the amp.About the only thing you can try here is updating the firmware on the player to be sure it isn't sending an errant signal, and plugging it in to a good quality powerline filter (isobar type).
As you will probably appreciate,I know nothing about electronics.
I could spend £30 on this regulator thing and it may not solve the problem. What do you think ? I could wait until Saturday until I'm able to talk to my brother who is an electrician.Can I come back to you, if necessary in a few days if I have any more questions ?
