Whats your budget?
this should be in ICE section.


Front: 6.5 inch components, brands i usualy recommend to look at are focal and morel
Rear: nothing, better off spending money on front speakers, they are the ones you listen too.
Amp: 2 ch amp or 4ch bridged, alpine make quite good amps

Sound deadening and proper mounting is some thing you should consider, without it your speakers will sound hollow and lack bass, heres a diy if your interested in doing it yourself http://www.ozhonda.com/forum/showthr...ing-your-doors the work i see come out of audio shops is usualy not the best so your better off doin it yourself if your handy.
