For official dBDrag racing.

"The dBDRA considers speakers with advertised maximum diameters of 10 inches or larger to be woofers.
All of the woofers in a vehicle (10 inches and larger) will be counted when determining what class a competitor should compete in.

Every woofer in an Isobaric or Compound configuration shall be counted.
Hidden woofers (such as those found in Bandpass enclosures) shall be counted.
Passive radiators, ports, and vents are not considered to be woofers, and therefore will not be counted as such.
If the largest speaker in the contestant's sound system is smaller than 10 inches (25.4 cm) in diameter, then all of the speakers that are being used to produce bass shall be treated as woofers.

"Token" woofers are strictly prohibited. If a competitor has installed woofers in such a manner as to circumvent the competitor classification system, the competitor may be re-classified or disqualified at the sole discretion of the head judge."

In simpler words, you can have 8" speaker(s) upfront, aslong as you have bigger speaker(s) behind the B pillar. And are not considered token woofers.

Back to the topic. I would personally build a custom door panel to mount the subs in the doors. put the 6.5" in the kicks, the 4" mid stay in the dash, and the tweeters on the A pillars. You should be able to get away with mounting the subs in the doors, and still having room, and being able to open the window all the way. I'm planning on finishing my door panels this year, and mounting 8"s or 6"x9"s in them.

there is a very cool device made by a company called waves audio, we recently installed one , hooked up to infinity components and the bass was equal to what you would expect from 8 or 10 inch subwoofer. just make sure you sound deaden the door thoroughly and i think you would be impressed. the unit is called a maxbass mb130

You dont need a sub up front to get bass up front. The sub location is almost a non-issue. Your concern should be resonances in your car. Your brain will hear vibrating panels in the rear and automatically locate bass there. Even midbass can be used in the back of the car and have it appear to come from the front. You could spend less time and money by simply installing your JL in the back properly. If you have ever heard a car with the subs mounted up front, you might change your mind about them. Some are very nice sounding, but many sound poor or worse. Its a huge install challenge, so do it correctly.

Well said. Simply put, bass has no direction, it is all encompassing. People put subs in the back simply because that is, traditionally, where there is ample room to construct an enclosure.

See if you can fit an 8" or 2 below the dash between the foot area of the driver and passenger. I think I can fit one and will be building a bandpass box to allow for only 75-115hz to escape from it if possible, as this is where the largest dip in my sound response is.
