Box placement questions, Which would be better?

I just completed a system for my buddies girlfriend in her 350 and I built a rearward firing box that fits in the area between the rear speaker pod and the strut bar that houses two 8" Kicker CVR's, and it sounds amazing. Sure, you can't hear the bass from 3 blocks away, but it has a ton of punch and sounds far more musical than the last 350 that I installed a single 12" woofer in. The 12" box that is in the picture looks cool, but I can guarantee that the 10" box would sound better. It is impossible to get great sound quality with 12" speakers when they are 10" away from your ears. Another thing you need to consider is the size of the box. It is very important that you get a box that has the right amount of internal volume for whichever speakers you get or they wont sound right. Most of the "prefab" boxes for the 350z that I have seen are too small for most woofers, so you may consider having a box made specifically for the woofers you end up getting.
matching woofers to the box as stated in this post is very important to optimal sound....well actually I agree with everything in this post
That's just total BS that 10's are more accurate than 12's. Don't believe that for a second. If you're running a good sub in a proper setup, the size of the woofer should not be affecting the accuracy of the bass. First of all your sub should be playing just bass, not the mid-bass as well. That is the duty of the mid-bass driver. If you have good mid-bass, it should be a lot easier to blend your sub and it will sound good regardless.

In a large SUV, 12's would be the optimal choice in speakers to get the best sound quality if the box is at least 7 or 8 feet away. In a standard cab truck or a small car such as the 350Z where the subs are usually just a couple feet or less away from the passengers, 10's or 8's will sound more accurate. I've had every different size and number of woofers in the last 15 years, from one 8" to eight 12's to four 15's. Just the other day I swapped out three 12" subs from my car and replaced them with three 10" subs, and using a lightly smaller box in the same exact place that I had the 12's the sound quality inside the car is much better. Every different setup that I have had with 15" woofers the in car sound quality was pretty bad, but standing 15 feet in front of the car they sounded perfect. 12" speakers are better, but the optimal distance from the listener is still usually at least 8 - 10 feet. This is why having the sub box face the rear of the trunk typically works better, because it allows more distance between the speaker and the listeners. It's all about the wavelength of the speaker and the distance from the listener, and because the 10" sub has a shorter wavelength than a 12" sub they will sound more accurate (not louder) in a compact car.
