You will probably want to pick up a bit more speaker wire, but I suggest you learn how to install it yourself if you want to save cash. I'm sure there's a more economical system out there, but every thing I have listed is from great manufacturers and will give you years of service. It's also all authorized and about $950. Before you ask, no, you don't need rear speakers, hook up the factory speakers to the headunit and you will be just fine.

You could also stick with the Basslink b/c it appears you don't have the time/resources to build a box, so, in that case, I would substitute the CDT comp set for the Kappas, again, buy no rear speakers (do you drive in the back seat or the front ) and instead of the 4 channel alpine, get a two channel. Then you can tailor your wiring kit to whatever selection you have made.

One thing I just noticed...you linked crutchfield for the head, but the price is way lower....unless you are saving over $30, get it from crutchfield, it will give you the dash kit and harness that you need to get it installed...
