Sub would only sound when am listening to radio would not sound when playing dud aux but surround speakers play

Possible that the connection to the AUX does not activate if you are using RCA inputs. Connect the DVD using the optical cable or the coaxial link and it must play better with surround and subwoofer in DTS.

Well this is and isn't a fix. I don't know what the underlaying problem is that causes the Amp to shut down but I have come up with a way to stop it from doing so. What ever the problem is it is triggering a circut on the board called "Protect" which can be circumvented. You need to start by pulling out the amplifier unit from the subwoofer assembly. You will see that there are two circut boards at 90 degrees to each other that are connected by 3 sets of connectors. You need to remove the screws and wire that hold in the board attached to the bottom of the assembly. You can then pull it out disconnecting the connectors. The connector closest to the power trasformer is the one that we are concerned with. On the vertically oriented circut board you will find a small map of the connector identifying pin #5 as "Protect". Inside the portion of the connector attached to the bottom board that you pulled out, use a small set of needle nose pliers to break off pin #5. Then reassemble the amp and put the subwoofer back together. I used this solution and it has been working since. If you have reservations about breaking the pin out then try just bending it out of the way and partially reassembling the unit and powering it up. Once you see that it does indeed solve the problem you can break it out. Like I said, I don't know why it started to turn off spontaniously in the first place but this does fix the problem.
