Ok so here's what I am considering.

I already have 2 Rockford Fosgate 10" P2's @ 4ohms (200wRMS)

I already have a Power Acoustiks 980W 2 Channel Amp (2x220wRMS @ 4ohms)

So I'll deffinately be re-using those. I'll purchase one of the enclosures for the subs on ebay.

I think I'll replace the front speakers with a pair of Infiniti REF6020CS Component Speakers (2x90wRMS@2ohms)

The rear speares with a pair of Infiniti REF6022I normal Speakers (2x60wRMS@2ohms)

A Kenwood KAC-8403 to run the four speakers (4x90wRMS@2ohms)

I'll do the DD Conversion and put in a Kenwood DDX6019 Head Unit


Any comments/suggestions are welcome, what do you guys think?

 

Won't get on the topic of personal preference in speakers, but i'd ditch the rears and upgrade on your front set personally.
