that would be a line DRIVER not a line output converter.People usually use line out converters when the have stock head units or a low preout voltage from the head unit.

you gonna keep the stock radio? if so, yes you need one.I have a 2003 ford focus with no audio upgrades... so more than likely I will need one?

it should be everything you need. it's just a small box IIRCis there any special wires I need to buy along with the converter?
Honestly naw, any good decent size speaker wire will work fine. I like to use 14 gauge myself when I do an install with one of those.is there any special wires I need to buy along with the converter?
