sub choices?

Wrong.
Sealed enclosures are the best for tight, accurate bass reproduction. If your looking for SQ then this is the way to go. Designed right extension should match a ported and it will play to higher frequencies than ported or passed. Less space needed. Amps will work a bit harder but not grossly inefficient.
Ported enclosures give up accuracy for volume and require more cuft than sealed. Better low frequency response/SPL in the tuned range than a sealed but wont "reach" as high. Definitely not as tight or controlled as sealed. Slightly more efficient than sealed (less amp demand).
Bandpass is for max SPL in a tight frequency range. More efficient/SPL in the tuned range than sealed or ported. Drops off significantly due to the tight range. Can be made to sound very good but hard to design and typically more cuft needed that both the above.
In any case its all about design and intent on use. Unless you want to give up a good portion of your back seat sealed is the best use case scenario for most people here and will sound better in a wider range of music.

I agree that advancements have been made in the audio industry and that the manufactures engineering has progressed drastically. However, the law of physics never change. Its ludicrous to logically assume a ported enclosure can have "tighter, more accurate response" than a sealed box.
The only thing more efficient about a ported box is, it takes less wattage to sound optimal. Which is obvious because of the drastically reduced pressure behind the cone. Hence, mathematically/physically it should be easy to see why they are not as accurate. With the driver having no back pressure the sub is free to resonate and bounce with infintestimally small back pressure. The continual bouncing and free resonance due to lack of pressure results in unwanted *noise* and inconsistent response.
Although no box is 100% sealed, a ported enclosures back pressure is still logarithmically less than a sealed. Thus, PV=nRT should tell you which is more accurate. Its fairly simple to see when you understand audible sound depends on pressure, resistance, vibration, and many other variables.
I would suggest a few courses in physics/chemistry dealing with bandwidth, frequency, wavelength, and pressure. They really helped me when "thinking" about audio products and other worldly matters.
I used to think the same thing. I also thought sealed were more "accurate" and sounded better. They do not. A ported box built correctly will have the twice the amount of output as a sealed enclosure with the same wattage and it will sound better. This is the old way of thinking, it is simply not true. You are correct in saying they take up the least amount of space. Dont get me wrong, I have had sealed enclosures and they have sounded great. If thats all the room you have, them by all means, use a sealed enclosure. However, if you have the space for a ported enclosure they can sound better and just as or more accurate then sealed. The trend for the past 20 years or whatever has been what you said about sealed enclosures, they have been figuring out in the past 5 years or so that ported actually sound better and are far more efficient than sealed. Everything depends on what you have room for and what your willing to modify to get what you want. A good sounding system can be achieved with almost any design as long as its built correctly and set up the way it should be. People that crank up there gains and max the the bass level out on their head unit don't have a clur on what music is suppose to sound like. They will learn with age hopefully, I was the same way when I was a teenager and even into my early twenties. You can do so much more with so much less nowadays, as long as your willing to let go of what you think you know and listen to people that have been doing this for 20,30 or 40 years. When I say you, its meant to be a general statement to everybody. I am still learning new things with audio every day. Somethings I just cant wrap my head around because of how I thought when I was younger, like the whole sealed v.s. ported thing. It is true, tried, tested. I have heard some subs mounted in just a single plate in a home that will blow your mind, no enclosure at all. The technology ad r&d that is put into some of this stuff is amazing. It changes everything we thought we knew about audio. Its kind of like starting all over again. As long as we are learning, know matter what its about, Im ok with that.

Crap well I think it's better to go with big brands since warranty and the portability of having many places doing the repairs and upholding the warranty for those big brands :/ it's light buying an iPod vs a cowon.
Anyways I need a suggestion as well I got an 09 scab and was looking at this

It looks kinda small would I have to get shallow subs for that? I really liked the Jl 10w1's their bass is really tight, compared to the ones with a rubber compound. I listen to mostly dubstep and hip hop.
Any other suggestions, I also heard the Rockford p3's but didn't like their wobble sound after the hit.
I don't mind splurging on the amp so for the speakers my budget wold be around 150 each
