It's worth mentioning that the speakers mounted in the seat-backs of our cars are NOT meant to be heard like main speakers - they will NOT be as loud or produce the entire sound spectrum of any music source. They are desinged to help create a 'personal' surround effect for only the person seated in that particular seat. They are NOT designed to add volume or fill the rest of the car with sound. Also, they will only activate if the sound source (CD, radio, etc.) contains 5.1 coding. If the source of music is an FM station, these speakers will not activate at all.
When playing 5.1 coded music sources or listening to digital radio such as some XM stations, the speakers will activate as the system decodes the info and sends particular frequencies to those speakers. They are desinged to 'fill' an area near the seated passenger's ears only. A passenger seated in any other location cannot hear these speakers and they are desinged NOT to sound like a speaker near your ear but rather 'enhance' or 'fill' the area surrounding the head of that person seated there.
In my car, I an only detect that they are working by tilting my head sharply toward one or the other speaker, or by lightly laying my fingers directly on them to feel the speaker vibration. If I switch the sourround system OFF, I notice the lack of sound near me, but with the sysytem switched ON, the speakers do not have any presence - that is how they are designed. Even if you increase the centerpoint volumes, that will NOT increase the volume to these speakers particularly, it will just enhace the virtual surround effect produced between ALL of the car speakers, increasing the shaprness of the central listening area inside the interior. Think of the seat speakers as 'virtual surround' - meant to increase the area of the soundstage but NOT meant to be detected individualy by your ear.
