GM car speakers in the 70's and maybe later versus other designs
Chryslers and maybe many other makes have the two left speakers
connected to the left channel of the radio. GM radios OTOH used to
connect the front left and rear right speakers to the left channel,
and the others to the right.
Or course, one can rewire his car either way, in most cases just by
interchanging two pairs of wires.
Can you all tell me more about
GM's use of the LF-RR/RF-LR method of wiring speakers,
what this is called if I want to search the web for it, and
more about its use by GM and possibly other places?
Also, in the opinion of the readers here, which method has more
Which is better for someone who is usually in the car alone?
With GM I guess if you're in the back seat, the violins aren't on the
left anymore, but otoh, the volume for both channels should be the
same wherever one sit. No one sits in the center of a 4-seate car,
on the console or half-way between the front seat and back seat, so
the Chrysler system, used by most cars maybe, has a disadvantage that
if you have someone in the passenger seat, he hears more of the right
channel and you hear more of the left.
GM's design solves most or all of that, although it lowers stereo
separation. And it depends on how often the driver will be alone and
how often there will be 1, 2, 3 passengers AND he'll be playing the
OT3H, with Chrysler's design, if you are driving and others are
sleeping, you can move all the sound to the left front and leave the
other speakers very quiet, so they can sleep. Or if you're the
passenger and the driver doesn't like the station you want (though in
my world the driver gets to pick the station) you can turn everything
to the right front.
