I'm not any sort of ologist at this but damn it should help. Please feel free to add.
In our case GM has asked Bose to OEM speakers and components for their vehicles. Since it's about production there has to be a "productive" cost. This means trying to get the most out of the least.
What I'm getting at is the noticeable difference of replacing the stock speakers with aftermarket. Most of the time you notice that there isn't as much "bass" or a lack of that bottom end output (most of this is the underpowering but there is more to it).
Your typical aftermarket speaker is more complex than that of stock. A 3 way coax for example has all its little components built into it to divide frequencies. Your stock radio does just this, either at the source unit or the amplifier itself.
The Bose sytem is a sytem. Each component affiliates itself with one another to make it work according to design. The speaker sensitivity and frequency response are a couple factors. The Bose speaker is designed as a full range. It has to try to cover a larger bandwidth. With this comes a sacrifice. Does our driver perform better on the low end or do we make it perform better on the high end?
There is more but this is to start the discussion. Just remember that the Bose and any stock "system" is designed around itself. Crossover points and filtration especially. Thats why when you replace with aftermarket there are all kinds of silly things you notice. Aftermarket guys build there speakers to perform more towards midbass midrange under the assumption the product is being used among other aftermarket equipment. Which why you usually notice a cleaner and more throaty change but not really as much bass. Between the filtration from stock components already and then crossover components on the driver your ending up with a signal coming in being broken up by all that before its output.
Just some general info. Real brief too....lol
