My DDX419 indash keeps showing DC offset error, I am aware that one of the wires is shorting to ground. Will this permanently hurt or fry my unit????

The error message "Miswiring DC offset" on a Kenwood DDX69028 stereo typically indicates a problem with the wiring or power supply. Here's what you can try to resolve the issue:
1. Check the Wiring Connections: Ensure that all the wiring connections are properly made. Verify that the power, ground, and speaker wires are securely connected and not loose or disconnected. Pay attention to any loose or exposed wires that may be causing a short circuit.
2. Check the Power Supply: Make sure that the power supply to the stereo is stable and within the specified voltage range. Use a multimeter to measure the voltage at the power wire connection and ensure it matches the recommended voltage for your stereo model.
3. Verify the Speaker Connections: Ensure that the speaker wires are properly connected and not shorted or crossed. Check for any loose strands of wire that may be causing a connection issue.
4. Inspect for Short Circuits: Look for any signs of a short circuit, such as bare wires touching each other or the vehicle's chassis. If you find any, isolate and insulate the affected wires to prevent further issues.
5. Reset the Stereo: Try resetting the stereo to its factory defaults. Refer to the user manual for instructions on how to perform a reset. This may help clear any temporary errors or glitches.
If none of the above steps resolve the issue, it is recommended to consult the user manual or contact Kenwood's customer support for further assistance. They will have specific troubleshooting steps and can provide guidance based on your stereo model and the exact error message you're experiencing.

GET THE USER MANUAL OR SERVICE MANUAL
AND SEE THAT THAT MEANS.
IT CAN BE,
12VDC TO THE (POWER) IS BAD 12VDC AND GROUND
OR (seems to me NOT POWER)

CAN mean one of speakers failing like this.(this)
1: shorted speaker, (CALLED VOICE COIL SHORTS
2: shorted speaker WIRES, to shorted to car body ground.
3 using wrong speaker if 2ohms is not allowed but 4-8ohms is allowed. or putting 2x 4 ohm speakers in parallel fails. as it will;./
4: amp is bad.(in the head end)


page 62 in your manual states

If the power is not turned on ("Miswiring DC Offset
Error", "Warning DC Offset Error" is displayed),
the speaker wire may have a short circuit or
have touched the chassis of the vehicle and the
protection function may have been activated.
Therefore, the speaker wire should be checked

THE REAL MEANING, (ME TOLD) IS ONE OF THE SPEAKER PRESENTS A OVERLOAD TO ANY AMP OUTPUT CHANNEL.
TO FIND THISONE MUST DISCONNECT SPEAKERS TO FIND IT.
YES SPEAKERS AND WIRES CAN SHORT.
A TECH EVEN TRIES TEST SPEAKER 1 AT TIME TO PROVE THIS.
IF ALL TESTS FAIL THE AMP IS BAD.

That error is normally a shorted speaker wire but starting the car won't cause that. Possible problem could be the dimmer wire was used as a ground by mistake. Lights come on when the car starts. Another is too high of voltage. Car rests at 12 volts but is around 14 when running. Was there a plastic piece on the red or yellow wire that got cut off during the install? They have a resistor inside that keeps the voltage down.

MIS WIRING" is displayed when there is a DC offset voltage detected at the speaker terminals ('+' and '-').

This is normally caused by connecting a '+' or '-' speaker wire to either GND or Vcc (+12V)

1. Collect cable not being used and make sure they are tapped off and reset

2. Remove a connected cable one at a time and press RESET

3. If after a cable removal and reset the error goes away, last cable removed was fault. Examine cable for short.

4. If you remove and reset all cables except for (RED, YELLOW, and BLACK) and you stilll have error, the short is internal of unit and requires service

I am also having the same problem.. any help?

You could have a speaker wire or speaker tensile (flex) lead that is shorting to ground, on a floating ground BTL head unit (all that claim 18-25 watts RMS per channel) all 8 speaker wires are always floating at about half of the supply voltage, IE if the voltage is 14.4 with the engine running the speaker wires will all measure about 7 volts to ground.

The flex leads are the wires on a speaker that go from the terminals to the cone.

Hello christo12385,

The DC error is most likely caused by a shorted or grounded speaker wire. Check all speaker wires, correct the problem, and then go into the sound setup settings and reset the POWER IC to ON.

Hope this helps.

Hello eklypss2000,

According to the manual for the Alpine CDE-102, the message "DC ERROR" is displayed if there is a short to ground in the speaker wiring. Check all of your speaker wires and make sure that no bare wire is shorting against the vehicle metal or against other wires. Repair or replace the wire as necessary. After correcting the problem, set POWER IC to "POW ON" according to the instructions in your manual.

Hope this helps.
