drthomps Posted June 23, 2004 Share Posted June 23, 2004 I have a new amp and a new speaker for my sub on a KSP-400 and it still has no sound. I've tried changing the red wires that must be connected with no results either. I do get the red light on the speaker back and I can see the speaker is getting power (and hear a light hum), but no music. New AMP, the cones are getting signal. Just no SUB. Any ideas out there? I'm dying for a little bass. Thanks, David Thompson david_thompson@mentor.com Quote Link to comment Share on other sites More sharing options...

drthomps Posted June 25, 2004 Author Share Posted June 25, 2004 What an experience... Sorry for wasting everyone's time. I had changed my connections to the speaker to banana plugs and in doing so, I had the positive and negative polarity crossed on the signal connections. The sub wouldn't fire with this crossed. Interesting, none the less, but pure operator error. Thanks to tech support for their work on this. David Thompson Quote Link to comment Share on other sites More sharing options...
