I installed a Pioneer DEH-P3700MP using the mounting kit from
Crutchfield that it came with, which looks fairly cheap and has a less
nice "pocket" underneath. I was looking, at it seems like I should be
able to just install it like the previous unit I had (they're BOTH the
same size.. i previously had the hyundai fm/am/cd).

Has anyone installed a basic aftermarket stereo the normal way, and
skipped using the whole mounting-kit on a 05 Sonata? I don't like the
cheap plastic mounting kit's "pocket" :/
