Here is the kit. It uses the factory knobs. This car is a beast of an install. It's such a pain the a$$. I would recommend you go your local car stereo shop to have it professionally installed. Depending on the system already in there, you may need to bypass the factory amp, which is not hard, but requires a bit of knowledge. A pro would be your best bet.
