My BOSE sound cuts in and out. ?

Are you sure its not just a duff cable?

Can you swap the cable for a known good one? Or even, if its one of those cables with 2 plugs at each end, change both plugs over ta both ends and see if the problem moves to the other channel: problems moves - duff cable.

Its possible you have cracked a solder joint where one of the connectors joins to the circuit board, whilst struggling with a tight plug. That should be a simple fix BUT it will means dismantling the unit to get to the board. Do you have a techie friend with a soldering iron and the ability to us eit?
