What speakers should I put in rear?

Not brands but what is typically the better setup? I know that rear soundstage isnt really important but i have 2 way comps in front and a 10" sub. this is in a hatchback so the rear speakers are are in the side panel by the back seat.

Should i go with comps, coaxials, or just a MB? i want to put a computer in evenetually and with that will be DVDs. So ill want some sort of rear fill.

What do you all think??

Try to match what you have in the front if you have the funds. 

If not, buy cheap.

Huh?  Maybe I'm having a brain fart but what is an "MB?"

My opinion on rear-fill?  For sheer functionality, something clean that makes noise is really all ya need...  my periennal rear-fill recommendation is always the Infinity Reference line.  Completely underwhelming in every respect....  but a clean and flat reponse.  Cheap too.  Yea.. anything that fits and costs $75 or more be just fine ...

'Course, like kfr01 says.. go with the comps if you can.  Componets for rear-fill really makes a statement, I think.
