Hey there!
I've just installed a new Sub and amp (brandnew) wired her up as per usual and worked fine for a few minutes when testing. However now has developed a deep and repeating 'thudding' 'thumping' noise. When my system is turned up it drowns this noise out, however it is always present.
Any ideas? I've tried reversing wiring and checked my grounding etc... Cabling all seems kosha? Any help would be greatly appriciated!
Cheers guys!

Sorry to hear you have a problem with your new sub & amp .
Have you tried adjusting the gain control as too much can cause clipping.
Is the sub in a dedicated box ? Did you make it yourself ?
If you are happy with the wiring try another sub as you may have a faulty one.
Cheers Kev

Re: Subwoofer making off Thumping noise?
Out of Phase wiring (+ and - the wrong way round) would have been my bet. I'm gonna go with Kev and the box being the next line of enquiry?murphymanuk wrote:I've tried reversing wiring and checked my grounding etc.
What are the power values of the amp and sub?
