Im currently looking at this:
Headunit: http://www.sony.co.nz/product/cdx-gt600ui
Front Speakers: http://www.sony.co.nz/product/xs-gtx1621s
Rears: Not sure
What do you think so far? As you may tell i like sony, ive had them before and never had any issues, if you can convince me other wise im all ears

Also not sure what rear speakers to get, i dont want 6x9s as i would have to cut holes in the rear parcel tray which i dont really want to do
