I would definitely recommend sound deaden-er if yours ends up being unusable, etc. as I recently replaced mine. The deadener was tore up and had a wicked smell so i cleaned the floors and installed Eastwood X-mat. Amazon now has their own brand which is popular with the car stereo crowd.
Additionally, I searched all around for best price, etc on carpet and actually ordered it on RockAuto. I think the extra money was worth it to get the 'heavy-duty backing'. If you need red, I wrote up a post on another forum that may help you determine correct color at

Make sure you take pictures or determine the 'correct' way to install the driver and passenger seat belt holsters; a lot of people cheat and take the easy way out by bolting it on top of the carpet..
Good luck!
