Car DVD player....?

Question

Just had Invision DVD System installed in my tahoe, when the surround sound is on I can hear a whistle coming from the speakers every time the gas is pressed, everytime it accelerates.... what could cause this? Any suggestions?

Answer 1

Ground problem.

Answer 2

It is probably not grounded well. Take it back.

Good Luck...

Answer 3

It's called noise, or signal interference.  Check with the place that you had it installed and tell them about the situation.  Usually they will install a noise suppressor.  Essentially what is happening is your alternator is feeding magnetically charged power into the DVD player, which crops up in the audio system as static-or the whistle noise that you are hearing.  It used to be a huge problem in car audio.  Good Luck
