Try using sentences and periods jdoria they work really good.

oops

Try using sentences and periods, jdoria.  They work really good!

Try this:  ground the head unit to chassis using a separate ground wire.  You could even experiment with running a ground wire from the deck directly to the battery ground or neg terminal.  And heed the advice above about the amps' grounding point.

I think I found the [problem to the engine noise. I pulled out the deck thinking the stereo had a bad ground, I looked and I saw antana wire spiced in an looks like a wire from an extention cords all the way to the back. If I replace that with a new antana wire would that fix my engine noise?

if an antana wire is bad  could I get ,would that make engine oise?
