I am getting terrible and muddled sound from the Ipod hookup in my car.

The setup is Ipod 4G to a PocketDock line out to a Becker 4602 Aux in.

I suspect that the Ipod isn't driving the Aux in high enough. The same setup
works fine on my home stereo. I have also tested the Aux in on the Becker 4602
and that works too.

Does anyone have any suggestions?

Or how build/buy a line level amp?

Thanks.
