12's would be better for a louder setup but since they are W6s I don't think that'll be a huge problem. I'm running two Memphis M1s and they are more than loud enough I have to turn them down after a few minutes. For space and getting a perfect size box I'd go 10's. 10s are also a little more accurate. For amps I'd consider, Arc Audio, Memphis, eD. Not extremely well known names but don't let that fool you.

Model for model in both of their optimal box sizes and power rating a 10 will be more accurate. But of course the 12s in mine sound louder than 2 10s. Also I haven't come across any boxes for 12s that just slide in the Mustang trunk. Seen quite a few 10s though.

Ampwise I say spend a little more money on something better. No offense but Profile doesn't really scream quality. And trust me if you look you can find better amps for not much more.

for the box im thinking as tall as possible and aslongas possible. width on the other hand im not sure i wanna say have it come to the edges of the gay *** humps in the carpet. room really isnt much of a problem in the car so im not trippen over it. Price for a amp, well I cant really say there is no price because im not special like that. But I want it done right the first time. my boss says that a JL 1000/1 will drive the subs with ease and he also says that JL under-rates there subs watt handling capabilities.
"My boss has 3 12 SW91 series Eclipse's in his Intreped and there run by a Eclipse and Diamond amp."
not sure y I just told yall that but ya.

$600 for amp

You are completely wrong. What science are you using to come up with the incorrect statement that the two sizes of subs will have different sound. My 12 for instance in more "accurate" then even a set of 8's I have. A speaker is merely a piston that moves air at a given frequency. If the box is built to spec there is a certain "backpressure" on the woofer. Following Newton's seond law the enclosure will create a force on the cone of the woofer pulling it back into the enclosure. For a 10 or 12 in the recommend enclosures (with the same backpressure) and operating conditions, there will be no difference in the accuracy of the two woofers. The force from the box of the 12 would couter act that of the woofer with the force required to bring the woofer back to refernce point. If a 10 was given the same conditions it would move with the force required to bring it back to reference.

Basically, all things being equal a 10,12,15,18 or any reasonable sized woofer will react in exactly the same way, creating the same frequency and the same accuracy. I assumed a rigid cone, but with high quality woofers that assumption would be correct, otherwise it would deflect greatly from the forces of the magnetic reaction causing the speaker to move outwards and the opposition force moving it back inwards.

If you are "coming across" boxes that means you are buying prefab, that is the cause of you lack of "accuracy" from a 12.

Now that your learned on that... subject 2.

Profile amps are very reliable, and contrary to many bargain basement brands put out thier rated power. Have you ever own a profile? Probilbly not, i own two along with my diamond audio, fultron and concept amps. They are stout for the price and if you do have a problem the warranty service is great. I received emial corrspondence from an American, and I beleive he was also the tech that repaired my amp. Overall, my impression of profile is stellar from a low budget standpoint, and you will find other knowledgalbe people with more then likely share the same opinion.

Please do as much homework and reading you can before you give people advise. You can cause them to make uneducated decisions. It seems as though you are somewhat knowledgeable, so please stick around and give advice where you do have expertise.
