I have a dual cd player in my 96 maxima.

when I'm not driving the cd player works find no problem.

but when i drive down the street even the smallest bumps that you cant hardly even feel the cd player skips.

when i put the cd player up right, it works perfectly. dosent skip at all.

I check all the srcews and there all tight and in the right places. what could be the problem?

or should i just get a new deck??
