Just to update, my Alpine 9856 is now installed, with the Ipod "full speed" cable.
I can now enjoy, and browse my 4 gig nano via my head unit controls.
I replaced the factory fronts with Alpine type R 6x9's.
A bit of a trim was needed to make them fit. Everything is faded to the front, no rears at all.
I am quite pleased with the sound, to the point I may not get a sub.
I figure just amping the fronts will make a good enough improvement.
Hell, i'll get a sub eventually.
