Hey Fox,
Are these the same speakers that you had the problem with a little while ago?
If they are; then, the best solution I can offer is to get some aluminium foil and wrap it around all the connector plugs from the speakers and see if that helps. [a rough 'fix' but highly effective with those "oldies"!
