For speakers I'm after some small speakers (4" or 6") for up front and some decent 6x9s in the rear.
Headunit requirements is cheapish ($2-300, can get trade prices at repco) and a front USB port.
No room for a sub and don't need massive bass as the car already vibrates enough, but some would be good. So just 4x speakers, a headunit, and maybe an amp if required?? I've run Sony before but the headunit didn't last too long. The guy at repco said Sony is crap and run with JVC - now as much as I'd like to believe him I'd prefer some other opinions

What decent brands should I look at?
What are the important numbers to look for regarding speakers/headunits?
Cheers
