OK, here goes. I have been using a KSW-12 sub for close to two years and it has been great. Lately though it's been flaking out and I need my bass. It gets a signal from the receiver but there is no sound. It's connected via the LFE port (using T connector) on the sub using a Monster Cable sub cable. I've noticed that if I jiggle the connection I can get sound but it will not stay on. I'm pretty sure it is just a loose wire. Is there any way to open up the sub to get to the back of the LFE connector?
