ISO Speakers help

[EdSalinas]

Hello Guys:

Im so frustrated, recently my car radio was stoles...The one who did it cut the speakers wires and now I have a nightmare to try to find sound when I conect a new sony CD-Radio deck.

I tried all the color convinations with the speakers wires, also I tried to find continuity with a multimeter...but have no continuity even when I check directly from the speaker wires to the front door spesker connector.

Does anyone knows if its any secret to find the continuity after some one cut off the speaker wire harness.

Maybe an amp. is damaged?

Thanks for your help

Ok,
You PROBABLY have a factory amp installed behind the right rear panel. If this is the case, your not going to get continuity from the head unit to the speaker. There are 2 different wiring harnesses in the dash. Did they cut both?

 

[EdSalinas]

Yes they cut both...

I tested the power & ground wires and the antena with other radio and a extra speker and it works fine...

So the new radio is not the problem.

And yes .. have no connectors at all... just the power, ground and the speaker wires alone

OK
You know which cluster is the "power harness". The other is the speaker harness. It is VERY simple to find which wires are for which speaker, as well as polarity.

HOWEVER we have 1 small problem. On the power harness there is an amp cut on wire, and I can remember which color it is. You have to have your head units power cuton wire connected to this for the amp to turn on. There is one way to do this, that im not particularly fond of, but it may work. I believe there are 8 wires on the power harness. 2 of which are power and ground. We can knock those out. There is one for headlight illumination. 1 for amplifer cuton, 1 for power antenna, and 1 for something else that i cant remember. You can try to hunt and peck for the correct one. As long as your headlights are not turned on, nothing SHOULD happen. This is NOT, repeat NOT the best way though. If you have any other means of finding out the pcon, please do so.

Once you get the pcon situation figured out, then you can start on the speaker harness.


There are 8 wires in the speaker harness. 2 per speaker. All you have to do is get a wire pair, hook to 1 speaker out from your HU, and just start the trial and error process. If i remember correctly, Both +, and - speker wires are next to each other. Should take about 45 minutes to get all phases correct.

Ok this is the wires I can see

The ones for power are

Orange-black
Red
Green-yellow
Blue-Red
Blue
Yellow-Black
Black

If I connect the orange-black to the power in the new radio, and the black to the ground and the antena ... the radio works...




And a fat one with 8 inside... think those are for speakers

Green
White-Green
Light Blue
Blue-black
White-orange
Yellow
Brown
Violet-white

 

[Fhantazm]

OK i forgot one more wire in the power harness.
There are 2 for power, one for switched power, and one for memory. They are probably right next to each other.
The RED, and the ORANGe/black. Do you have a multimeter??

 

[EdSalinas]

Yes I have multimeter...

What do I have to do whit the multimeter?

 

[Fhantazm]

Your going to need to find which one of those wires are constant 12v, and which one is switched. Just take the MM, and put the negative probe to the ground wire, and with the key off, put the positive wire on the orange-black, and see if you have voltage. If you DO then this is your constant 12v line. If you dont have voltage, turn the key, and you should get it. This would then be your switched line. Just do the same with the other wires until you either find the switched power wire, or the constant power wire(whichever you have not identified yet).
So now we have the following mapped.

Orange/black-power
Red-power
Green-yellow
Blue-Red
Blue
Yellow-Black
Black-Ground


That leaves the following un accounted for:
Green-yellow
Blue-Red
Blue
Yellow-Black

I know 1 is amp cuton, 1 is power anteanna(not needed), and 1 is light illumination control.

I BELIEVE one of the blues is for the amp cuton. Im thinking solid blue, but not totally sure. I would try those first. Just hook the power cuton from your HU to one of the blues(try solid first), and a speaker wire from your HU to 2 wires on the speaker harness. If you get no sound, try leaving one wire still attached to the , and move to a different wire within the speaker harness. If you still have no sound, you probably dont have teh amp cuton. Try moving to the other blue wire, and do the same thing with the speaker wires. Its tedious, I know, but without a wire colormap theres not too much more that can be done.

Also I just want to say that I am doing the best i can from memory here so keep this in mind.

 

[EdSalinas]

Thanks a lot for your patience

12v when switch is on ..... Orange-black
12 v continius .........Red
ground ..Black

Green-yellow
Blue-Red
Blue
Yellow-Black


So this will help me to reset the spekers?

Sorry for taking so long to reply, had a small emergency popup.

Just go ahead, and do what I suggested above to try and find the correct speakers. It should work
