RE: [DML] Re: Re: Grounding Each Speaker Individually (was: soundsystemupgrading)

["Video Bob" <videobob@xxxxxxxxxxx>]

The harness has 9 wires, I will break them down for you.

1. Constant 12 volt
2. Power on 12 volt
3. Ground
4. Front Ground
5. Left Front
6. Right Front
7. Rear Ground
8. Left Rear
9 Right Rear

Both the front and the rear will share the common ground.
So when the harness adapter is wired in, you will simply wire both of the 
front (or rear)
ground wires to the single ground.
Other wires for ATT, Antenna, AMP Trigger, etc run from the head unit and 
hook up
separately and without cutting in most cases.
The antenna control wire, blue, will plug directly in.
The ATT, used for auto muting installed cell phone systems is almost never 
used,
and the AMP trigger must be run to your amplifier to turn it on and off.
It is reccomended that if you do install an amp, run it's ground wire from 
the same
location as the radio to prevent a HUMM or "ground loop".
Using my harness adapter in this way allows you to connect a new head unit 
to the
existing Delorean wire harness without making a single cut to it.
Instead, my wire harness is the one that get's patched into the head unit 
and will
simply plug directly into the original Delorean wire harness.

This is how my unit is connected and works fine.
If for some reason your head unit needs separate grounds for each speaker 
you would need
to run your own ground connections, however this has never been a problem 
yet.

Alternatively, the other end of my wire harness that is chopped off can be 
added to
the original Craig radio and it could be hooked up to another system if you 
desired.
You could also get (or build) an adapter for your Craig radio and have the 
ability
to quickly pull out your new DIN head amp unit, unplug it from the harness 
and plug
the original Craig back in for use at car shows or concourse competitions.
The switch would take seconds.

* Note:
If you are doing a major radio upgrade, in which you will either cut or 
replace the console plate
to accomadate the new DIN stereo, you will need to remove the center console 
cover that
runs through the middle of the car.
All of the wire harnesses run through this part.
It would be wise to buy 3 sets of 12" RCA stereo cords and run them from the 
head amp
to the back of the car under this console just in case you decide to add an 
amp later.
The 3 sets are for front, rear and sub.
...that is if you plan on adding a speaker box, amp, etc.
But you never know, so that's why I reccomend it so that it is there and you 
won't
have to rip the console apart again to add it.

So far I have sold about 20 of the harness adapters without a single 
complaint, and my
instructions were put together well enough that so far no one has called me 
for tech support yet.

If anyone has any questions please contact me directly.
Thanks.
