I am having intermittent issues with the output on my D3. The LF speaker output will drop dramatically at times, often when the unit is jostled. I first thought it was a wiring issue, until I played with the balance and realized that it wasn't grounding, the output level was just lowering in that speaker. I then found that if I turn the volume up past 33, the sound will come back.

It seems like a processing issue with the balance.

Any thoughts or experience on this issue before I contact Pioneer and have to send the unit in for repair?

Bump...I'm the only one that has seen this?

It would seem so.

I have a similar problem,

my LF speaker will get cut off randomly....for some reason...if I turn on my headlights or press the brake...the sound may come back..

sometimes it just cut off and come back by itself

Do you find it across sources? I'm pretty sure that I have experienced it with the radio as well as with my Ipod. But I cannot remember it happening with the radio for sure. So it may be an issue with my Ipod or Ipod interface. I am trying to confirm that.

If I am instead able to confirm that the issue occurs with the radio as well, I would thing that it's a processing issue which will require it to be sent back to Pioneer. I'm hoping its the former.

A bump to once again see if anyone else is experiencing this,

An update: my sound loss in the RF speaker is across inputs, which rules out an Ipod interface issue and would appear to indicate a sound processing issue.

I'm probably just delaying the inevitable, and will have to pull it and ship it, but I wanted to give it one more shot.
