I've just noticed that my dvd player fades to the left. It only seems to happen when my head unit is in aux mode. I'm using a Sony CDX-M630 head unit and a Pyle dvd player. I'm not exactly sure what it could be. Everything else is properly balanced.

My rear right speaker also makes a beeping noise sometimes. I'm not sure what is causing that either. It's some sort of tapping i guess. I've heard is come from other speakers as well. It sounds like dut-duh-dut,dut-duh-dut,dut-duh-dut if that helps.

Any help is greatly appeciated.
