Hey everyone... I'm brand new here - just bought a unit a few days ago. My question is this: I've seen people talking about using another head unit for a tuner; would it be possible to go the other way? That is, use an AM/FM/cassette receiver with aux ins instead of having to add an amp? I've got space for two units, and the one I have has an aux in plug.

Reason I ask is that I really want to use the rio, but I can't afford the amp with installation, etc right now (starving college student and all that).

Thanks!
