Educar has been involved with training 12 volt professionals on process, theory, and system design for many years. These articles address the process of selling, installing, tuning, and how to present new audio system technologies effectively.
When I entered consumer electronics in 1986, I got a job in a “stereo store”.
The field we’re in is still often called “car stereo”. We install car stereos. The word “stereo” is so ingrained into our culture, we don’t talk about it much.
When I started doing OEM integration, and when I started explaining it to others, the assumption was always that we were starting with stereo - two channels, left and right, and two speaker systems left and right - which would give us a phantom stereo image in between the speakers if everything went right.
Then we came across some odd center-speaker systems.
Then we found out that Bose did some odd things.
Then we found out that Harman did some dumb things.
We have now identified six different stereo presentations used by automakers, and you should know what they are! One reason you should is that if you don’t know how they work, they can interfere with what you plan to do in your upgrade. Another reason is, if you know how they work, you can take them into account in your sale, and deliver a better-sounding system at a higher average price.
