My surround sound system keeps cutting out at higher volumes. Please help me find a way to stop it happening.

I'm using a Panasonic SC-AK600 receiver; it has 5 speakers and is programmed to receive digital signals. It's plugged into both my DVD player and Xbox 360 through a coaxial cable and optical cable, respectively. When the volume is at higher levels, all but the center speaker cuts out. And it cuts out at a single instance of sound (such as a sudden explosion or noise in the movie/game). I know that this may be some kind of safety feature to keep the speakers from becoming ruined, but I feel that the volume should be able to be higher.
Important point: the volume only cuts out when it is receiving a signal in 5.1 surround sound. If I'm not watching something in that configuration (ie, noise is still coming from all speakers; it's just not in 5.1) I can turn the volume up as high as I want, and nothing happens. So, I know that the fact the volume can't be higher is something to do with it receiving a 5.1 surround signal. The receiver is meant to be able to play this, so I don't know why this keeps happening.
Also, my left surround speaker has some additional speaker wire I had to hook up to it to extend the length, and has a lower volume than the right surround speaker. I don't know if that's a result of the additional speaker wire or not. I know it has nothing to do with settings on the receiver because I've checked that. Anyway, does this lower volume or additional speaker wire on the left surround speaker have anything to do with the speakers cutting out in 5.1 surround sound? I'm no sound expert, but thought I'd throw that out there for anyone who may know.
While I'm at it, there seems to be a slight difference between the audio coming from the TV and from the receiver's speakers (again, only in 5.1) when using the DVD player. I usually just turn down the TV's volume to 0, but feel as I shouldn't have to. There's an HDMI cable running from the DVD player to the TV. And again, the receiver is hooked up directly to the DVD player.
Thanks for reading this whole thing. Please help me with any knowledge/experience you may have.
