As for the R&D with the car companies, the mainstreem auto companies have to research much more, such as crash safety, fuel economy, research on who is buying what, how to mass produce the cars (this is a HUGE part of R&D, which I realized after going to a tool and die shop for a few weeks. Some designs that the engineers come up with cannot be stamped out of the metal), how to save money on the cars (such as by saving a little scrap of sheet metal on each differential cover stamped, after x diff covers, they will have saved y dollars), and the list just goes on. Plus, they have to worry about being sued, and advertising, and all that fun stuff. Ferarri has it easy though, they just have to build one hell of a fast car, and sell 1 less than what the market wants so that their is always a demand for them.
This does relate VERY well in my opinion to how the audio market works. Companies like Adire and JL play their own game, much like Ferarri. They know that the people serious about audio will come to them, so they dont need much advertising, and they dont need to try to make their product look better than it is. However, companies like Audiobahn spend their money in things like advertising, making the product look good, and stuff like that (which is why IMO all "mainstreem" speakers look ugly, because they try to look massive, when in reality, they have weak magnets, and inferior stats). Just like car companies, the mainstreem ones will get you by, but the people serious in the industry take it a step farther, and pay just for the R&D of the product rather than all the other nonsense that is required for mainstreem stuff.
I really shouldnt keep adding on to this, heh, I think we all got our points across a few pages ago
However, the one thing I have learned is that nobody is any more right or wrong if they buy Pyle, Kenwood, Kicker, or JL, just as long as they are satisfied with what they purchased, because in all reality, if a car audio system is only worth 10 dollars to someone, then thats all they should get, otherwise they will be spending money better spent on something else to them. I still remember being in a minivan with my girlfriend and her friends, and her friends had the stock radio turned all the way up, way past distortion. I personally could not stand it (I mean, being in a minivan is bad enough, and poor music makes it even worse!), but it was what they wanted, so thats fine.
