RE: [DML] Re: Grounding Each Speaker Individually

["Video Bob" <videobob@xxxxxxxxxxx>]

I know that this issue is getting really old, and redundant I might ad....
But let's review my method and let me know if you are talking about 
something different.

First, let's identify the "Ground".
The only ground placement I know of is a small cluster of loops that are 
bolted to the right rear of the console. These in turn run the length of the 
wire harness and ultimately end up on the negative terminal of the battery.
There are more grounds placed within the engine, the frame and a braided 
copper wire that links to each piece of body work.
Is this correct?

Now, let's assume that the ground for the stereo is the same ground for each 
of the speakers.
Assuming that these are the same, then would it stand to reason that if all 
of the speaker ground connections where also tied to any other ground point, 
be it the stereo or the wire harness then they would all be grounded to the 
same source?
If this is true then only the speaker output "hot" wires need to be 
separated and distributed
to each corresponding speaker.
Meaning, that if you took my wire harness adapter and took each of the 
speaker ground connections as well as the power ground and crimped them all 
together, and then ran each
of the speaker wires to the corresponding speaker then you should be able to 
wire the harness adapter in such a way that all 9 of it's connections are 
used correctly when wired to the stereo
in this manner, that when plugged it everything would work properly?

This is what I did, and it works great.
Maybe the exception is my particular stereo allows this type of grounding.
My argument is that there is only ONE ground source for the car and it is 
all universal,
so what difference does it make how the ground is made, rather from the 
harness or
by a separate direct line sent to another ground point.

Does this make sense?
