I purchased the system ~3 months ago, everything was perfect. When I woke up this morning I thought my main speaker had shorted somehow. I just figured out that the left black/red connector ports are not working anymore. I was wondering if I'd be able to put both red and black wires in the same port, it works but, I don't know much about electrical current, wattage, etc. Would these two connectors end up going bad? I really wanna know how this happened and it's been 6 hours since I was on the phone with Klipsch and I haven't gotten an email back, yet. Thanks for the help if possible!
