im just wondering which one would be louder....to have 6 lower rms subs say 200 rms each......or would it be better to have 2 subs that can handle 600 rms each?

Efficiency is the biggest thing people dont consider when buying a sub. They look at a big rms or max out number and want something huge. I had two jlw1's those subs push 150 watts rms, but they are some of the loudest 12's if you have them in the right application.

but what about the aspect of pushing more air comes into play doesn't it?

For the sake of the abstract question, the 6 subwoofers would be substantially louder than the 2.

Generally speaking, if output is the primary goal, cone area should be a prime consideration.

Larger power numbers are great for low end extention - efficiency is generally more desirable for sheer output.

But with more subs comes more space given up and more weight to carry around in the vehicle. You have to consider everything.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

The cone can only move so far on subwoofers. You'll push way more air with surface area than excursion of a high rms sub in your case. Its simply just not logical to waste your entire trunk trying to fit 6 subs in, thats why most people put 2 12's in the trunk and be done with it.

It's not all about cone area; 2 12's are going to dig deeper than 4 6's...

Enclosure is a bigger factor...I'd rather take two nice 12 inch subs in a nice ported enclosure than 6 low quality subs in a sealed box since thats all you could probably fit.

Not necessarily. It depends on the speakers and the enclosure alignment. I have build a sub using a single 6.5" driver that hits 28Hz with ease.

Well naturally, we'd be comparing the same type of driver, just in a different size. It would not really be a valid comparrison if done otherwise...
