I just installed a pair of NVS Tryants and I can only get one to turn on. I have the quick disconnect system on them so I can swap one set for the other, therefore I know both set of Tyrants work. I am running them from a KX850.4. <BR> <BR>When I use the fader to just the tower speakers and then move the balance to the right (drivers side) speaker, that speaker works. Then, when I move the balance to the left (passenger side), the right speaker stays on. All the while nothing is coming from the left set of Tyrants. I tried swapping the speaker wires at the amp, still only the right side goes on. I tried swapping each set, still only the right set goes on. I tried swapping the RCAs, again only the right set of Tyrant come on. <BR> <BR>I have not tried the 9V battery test yet to make sure the speaker wires are not shorted out. <BR> <BR>Any other ideas???

Here are some pics of the speakers. <BR> <BR><img src="http://www.wakeworld.com/MB/Discus/messages/65921/582215.jpg" alt="Upload"> <BR><img src="http://www.wakeworld.com/MB/Discus/messages/65921/582216.jpg" alt="Upload">

Try switching the wires at the amp end. Maybe half of your amp isn't working. Either way that will help narrow it down.
