Question Help deciphering Ford's wiring codes (stock subwoofer)

I'll be blunt, this is going to be a long-drawn post simply because I've never done this before.

When my truck was originally purchased, the original owner opted to buy the "upgraded" sound system which includes a sub-woofer and a small amp to power said sub under the center console. I've since installed an aftermarket player and I'm trying to figure out how to use the amp and sub-woofer already in place.

My problem is that I'm unable to figure out what wire powers the amp and which ones drive the sub.

Aftermarket dual-DIN player.


This is most likely the connector I need.


This is the factory amplifier. The four solid-colored wires (white, black, red, blue) are the sub-to-amp wires. The large connector goes up behind the dash.


These are the wires found on the connector that exits the amp.




The connector contains the following:
  • Red/Green
  • Red/Green
  • Blue/Black
  • Blue/Black
  • Red/Purple
  • Green/Purple
  • Green/White

With a test light, I've been trying to find what wire turns on the amp with ignition/key. All I've been able to determine is that both Red/Green wires are constant 12v leads. I'm assuming that the Blue/Black wires are grounds.

That leaves:
  • Red/Purple
  • Green/Purple
  • Green/White

Note that these wires also appear on the small connector I referenced to above. I'm assuming that means that two of them are the subwoofer's positive and negative terminals, but I have no idea what to do now to determine which is which.

Any help would be a blessing. Hell, help me finally figure this out and I'll send a couple of bucks your way.

Specs:
Ford Ranger FX4 2009
Pioneer Premium Sound System

Are you wanting to know what the white purple wire is for correct?

I have the same console it is the 290 watt Pioneer system

The amp is right behind the sub in the console. The Sub is located directly under the cup holders.

I cant find which connector is which

I've made PROGRESS! Okay, here's what I've done:
  1. Reinstall the stock head unit and plug everything back in.
  2. Ensure that the subwoofer operates as expected. Passes with flying colors.
  3. Undo a single connector, restart the car and check whether the subwoofer still operates.
  4. The terminal powering the subwoofer is the suspected 4-wire unit. Other connector is off and sub performs flawlessly. (Hurray!)
  5. Using a voltmeter, check levels of all four wires while plugged in and operating.
  6. Voltmeter is grounded. Using positive terminal to prod.

Here are my results. THIS IS WHERE I NEED HELP!
  • Red/Purple: Steady 2v line. Turns off the subwoofer when "reading" voltage. I'm not sure if this means that this is the amp power on? If it's only 2v, is it safe for me to plug this in to the ignition 12v line on the other connector?
  • Stripped wire: As expected, it's a ground. No idea why the previous owner stripped it all the way through, though.
  • Green/Purple: Subwoofer "pops" when inserting prong into socket. Reduces the subwoofer's "power" roughly by half when reading. Quite an audible difference. I'm assuming this means that this is the positive terminal of the subwoofer and that I'm basically dumping half the signal into my voltmeter's ground, which would explain why the sound weakens.
  • Green/White: No reading. No activity. Assuming it's position or negative subwoofer terminal.

Okay, so I've spent a lot of time on this, posted on many forums and have been given several answers, most of them not so good. Long story short, it looks like the amp's power cable "talks" to the stock head unit which means that the stock amp cannot be re-purposed.

I'm now looking at installing my own amp under the passenger seat and use the stock subwoofer. According to this photo I've taken, the sub is driven by four wires (red, blue, white, black). I now need to determine what they are. I'm assuming black is the ground. Not sure which is power, though.
