RE: [DML] Re: Speaker Grounds vs Electrical Grounds

["Video Bob" <videobob@xxxxxxxxxxx>]

You may have a point on this one,
I never said I was an "audio" engineer, only "video" - HA!

In an effort to solve this issue, I am going to consult with my friends at 
"Crank It Up Car Audio",
they build competition audio systems.
I will show them my wire configuration, and ask them if it is correct, and 
if not what is the
correct way to do it.
If I find I have done it wrong then I will be more than happy to eat humble 
pie here
on the DML and give out the correct diagram.

Again, the result has no bearing on my wire harness adapter, you can wire it 
up any way you want!
