If you're gonna just go with a speaker set up I'd recommend Kenwood HQ 7 X 10, ~$240 from shop at bankstown, not sure if I can name shops but PM me and I'll send you the link to the site. Don't bother with 6X9's.

You'll need an amp to power these btw, I think they want 150w RMS cant remem, just check on the kenwood website, but u wont be disappointed with them.
