Hi

 

I bought a car DVD player the other day with a seperate monitor and it plugs into the cig lighter theres a headphone socket on the dvd player which one end is a jack plug and the other is three auxilary leads the instructions stated that these are to be used as auxillary in, to go into an external source. SO I plugged them into my car Sony CD player.

 

Now when the ignition is on and the unit is working through the speakers etc it is bloody ace surround sound and all that in my car.

 

but as soon as I start my engine Iget a whistle through the speakers gets louder as you accelerate. etc

 

Now all my leads seem fine and obviously it works great when the engine is off..

 

the auxillary in works fine through the cd changer so its not the head unit.

 

any ideas anyone please :headvswal

 

as Ive never had to look into things like surpressors before

 

I think thats what there called anyway :confused:

 

thanks

Try hard wiring the DVD player rather than using the ciggie lighter, you may find that you will need a Sony Aux in interface for you head unit as the one for the changer is for just the changer. Check the earth on your head unit, the original is earthed through the bracket but when some people fit aftermarked headunits when they plug the aerial in the stereo works so leave it at that rather than connecting a new earth.

If that fails try a ground loop isolator which plugs between the rca input to your head-unit and DVD audio out.

inline surpressor will fix that mate :D
