FC (coupe) stereo options? Little help.

[djmtsu]

I have a couple of questions guys. I am not a car stereo guru (I can install and wire them just fine) but as far as what is ideal, I need some help.

Currently, I have some POS system:
-Pioneer CD/MP3 player
-Pioneer 6.5" shitty door speakers
-Infinity 4" dash speakers
-OLD Sony 5.25" out back

All the speaker wiring is stand alone, I didn't want to hack the factory system with all the amps, and possibly get distortion.

It sounds like crap. I have the 4 front speakers spliced together, and the rears off of rear channel.

I am looking for another head unit (has to be DIN, I have a gauge panel), reasonably priced, has to have iPod built in. The door speakers and rear speakers need to be replaced as well. I prefer Sony, just because it has never done me wrong. I have a decent Sony HU in the Miata with the iPod cable, and it works OK, but not ideal as far as navigating playlists.

What do you guys recommend? I am not trying to spend alot of money here. I do not drive the car alot, but I want it to sound decent. I do have a 250W amp and 10" JL sub I can install, but I do not need it, and that shit is heavy!

Anyone?
