the rear deck will house the rear speakers only, the sub is in the front where it belongs
the rear deck will be fiberglass covered in black leather and perferated for the sound to get through.
i've been designing custom installs and competition systems for many years so i have a "trained ear" to the music i tune to. an rta will assist you in getting a "flat" response curve in the car which won't sound good (you can use an rta to find different resonanses in the car which will assist in crossover points/box design). a flat curve will only benefit you competing in IASCA which i don't plan to do. i'll be happy to share any info/ideas to whoever requests it, i've competed on the national level in the past but just got bored with the sanctioning bodies that ran the events, now i just do it for me/friends/work
