Stock Sub Wiring Harness

Anyone can figure it out with a Digital Multi Meter (DMM) and a few minutes.
1st: You need to use DMM to find accessory power, constant power, and ground.
- turn off the radio and car
- Set the DMM to DC voltage that reads from 0-20 volts. DC is usualy sybolized by a straight solid line with a dotted straight line under it.
- Ground the black electrode of the DMM
- Use the red electrode to probe the wires in the harness until you read +12 volts. This is your constant power wire, write it down you will use this for a VERY small bazzoka tube, but in general you should run a new one.
- Now turn on the radio and car (doesn't have to be running)
- use the red electrode to find another wire that reads 12 volts now that the radio/car is on. This wire should show nothing or ground when the car is off. This is your accessory power and will be used as a remote turn on wire, unless you have an aftermarket head unit. In that case you should run the remote wire form the head unit to the trunk to take the place of this wire.
- Lastly set your DMM to continuity this is usualy a sybol that looks like a little cicrle with round waves coming from it. Some cheaper meters have this built into its ohms (horse shoe shaped sybol) reading setting.
- Probe the remaing wires until the meter tones. Meaning you have continuity, you may have to turn the ability for the meter to make a tone, on. This is your ground.
2nd: The remaining wires are tapped to your speaker wires. There should only be 4 left.
- Remove your head unit and disconnect its wire harness.
- Get a small battery, AA or AAA.
- Get some speaker wire and put one lead on the positive of the battery and the other lead of th espeaker wire on the negaite of the battery. Now take the other sides of the speaker wire and try to push them into the subs harness until you touch the metal connectors within it. Keep moving around the wires until you hear a pop. The 2 wires your touching are a speaker. The remaining 2 should also be a speaker.
- Label these wires as + and -. Do do this you want to be sure that the battery causes the exact same noise to come form each speaker. If not, then you have the + and - reversed on one of them.
