Thread: Subwoofer wiring

appears to require 2 sets of POS+ & NEG= inputs to the speaker ... Hence 4 wires going to the Sub speaker


So I had another look at the plugs ... and this time, armed with a multi meter.




First thing is a correction of wire colour description,


1 small plug with 3 wires ...

Purple with Yellow stripe = 12v Trigger wire (Stereo ON)
Red with Yellow stripe = Pos+ LINE IN (Not confirmed yet)
Black = NEG- LINE IN (not confirmed yet)


1 large plug with 6 wires ..

1 side of this plug has the following wires >>
Green with Orange stripe = POS+ 12v
Black = NEG- (Earth)

.. other side of this plug has the following colours >>>
"Sea green" / Red / Blue / Yellow = Speaker wires
The actual identity of which is POS+ & NEG- and which is paired, has not been confirmed yet.

Bit more research by pulling the SUB box apart will reveal more.




So now, I have to chase the Audio LINE IN wires back through the wiring harness to the ISO plug at the stereo, so I can feed a active line to it.

G`day , ours has a pioneer .

With ours it was just a matter of using pioneer / iso plugs changing 1 wire in 1 of the iso to a different slot and then connecting 1 wire for the woof to the pioneer separate output .

All wiring was done at the head unit slot and only the woof was not just plug in .

I`ve forgotten now but spent alot of time working out what wire did what and what head unit might work , i don`t remember now which others may but the pioneer was one that had the extra connectors to run the woof and or amp .

Can`t help other than to say it`s easier than it appears to be .

... I found very little info on the net about this subject. So I'm doing this thread so as to make it easier for the next person.

I found the Subwoofer wires at the ISO plug at the Stereo end ....
Red with Yellow stripe = Pos+ LINE IN
Black = NEG- LINE IN

So I cut up and added some connectors to a old RCA lead, so that I could connect the stereo to the ISO plug and now have sound input happening ...



Now I have a new issue ... alternator Whistle through the Sub amp ... Now to find a way to suppress it ...
