This is my problem I have a CKO In-Car DVD Player 1/2din which get distorted when I turn it up?I can?t turn the volume no more the (1 Bar)
The car that I am using is a BMW Mini Cooper S I have the BMW upgrade Harman Kardon audio system, which has a powerful amp..
Because the DVD player has a amp and the head unit also has a amp?the is being amplified to many times in distorts.
Can anyone suggestion something that I could use between the DVD player & the head unit to reduce the distortion maybe something that reduces the power of the DVD player out put so I could turn it up and get a better all round sound.

sounds like distortion is being caused by trying to amplify a low volume level from the input device. try putting the ipod volume at a medium level and try again to see if the distortion goes away/reduced
First off, most Youtube videos have bad sound but most likely is you need to lower the volume for FLASH via the sound mixer. Both are using flash. Turn down the volume for flash videos. You also have volume control with the video themselves.
make sure your speakers are wired to the amp with correct ohm load, turn gain, bass boost all the way down on amp, zero out your equilizer on the cd player and turn it all the way down then start raising volume on cd player., when u can start hearing music thru the subwoofers adjust the cd player volume till the sound from your subs is at its peak without any distortion. then start raising the gain on your amp till you are happy with the sound. It gives you the optimal signal strength coming from the cd player and the smoothest sound.
The level control controls the input level coming from your head unit (receiver) to the amp.
Your Sony users manual is a little vague on how to best adjust the level and other controls.
Here is one method that some installers use and works well with most amps.
Most 10" subs sound best between about 80-100hz and below, so start out by setting the LPF at about 80hz. The HPF will not be used. Next turn the bass boost and gain all the way down. Turn on the radio and set all tone controls, bass, midrange, treble to flat, usually "0" on most head units. Turn the volume up to approximately 3/4 volume level or just until you begin to hear distortion. Now, back the volume down until the distortion is gone. Next turn up the gain control on the amp until you hear the subs start to distort then back the gain down until the distortion disappears. Next turn the bass boost up again until the subs begin to distort, then either back the bass boost down or back the gain down until the distortion is gone. You may need to play around with the bass boost and gain controls to get exactly the sound you prefer.
Have you tryed a differant audio input on another set or on that same set. Are the audio cables good?? If all this is ok then the D/A converter inside the unit is defective and most likely it wont pay to repai sorry
