I'd recommend something besides those kappa highs..
like image dynamis ctx..
as for a deck even the caddys factory cd player is subpar compared to the 200 dollar cd players..
wiring kit my ***..
you can wire the cd player easily without a kit..
all you have to do is identify the acc the constant and the ground..
you might have a few others like a relay wire that turns the deck off when u open the door..
you can get a manual from autozone or online to find a wiring diagram..
also you can get a arc audio fd150.4 for about 250 which is superior to the kicker..
