Question about JVC Car Audio & Video

Am doing an initial install of a JVC R920-BTS. I havent hooked up any speakers yet cause all I'm getting is a message saying miswiring. I have checked the wires and the fuses and it all looks good. What would be causing this to happen?

Hook up the speakers and see if the miswiring message goes away.

If the speaker wires touched and the protection circuit didn't engage quickly enough, the output transistors may have failed. This is the most common cause for an amplifier to go into protect mode.

If you disconnect the speaker wires from the amp and the B+ and remote voltage are above ~11 volts (place black meter lead on ground terminal of the amp when checking the voltage), and the protect light still comes on, the amplifier will need to be repaired.

I have been working with Dell on this problem for quite some time. They tried replacing drivers, uninstalling and re-installing the card, replacing the card with a new one, etc, etc. Nothing worked. Sooner or later the error came back. Their last "fix" was to suggest that I restore the system to factory default condition and start all over again. I refused to do this. I had spent over 8 months adding software, tweaking it and windows, etc. They basically threw up their hands and gave up.

The Dell tech who replaced the card tried the solution noted here and "supposedly" it was fixed. A few weeks later the error came back.

So... I still don't have a fix for this problem.

If anyone finds one please let me know.

I'll check back here periodically.

SOURCE: my kw-avx840 was showing a

The faulty wire was shorting on the ground. When that happened the current flowing thru the amplifier top which that wire was connected got severely overstressed. This is why the safety system was triggering. By reseting it you were just making the problem a lot worse - you were forcing the amplifier to run with its output shorted. So it was to be expected that it eventually failed - it severely overheated and it got shorted itself internally. Now it's the short in the amplifier the one that is triggering the error message. And because the short is on a critical part you can no longer reset it - the power source itself has shut down.
The radio will have to be dismantled and the failed final amplifier identified and replaced, a job for a pro - time to take it to an electronics repair shop.

How to resolve miswiring problem on jvc steeo car

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

Unit warning check wairing than reset

It is caused by miswiring or shorted speaker line. You need to take it to service if it already happened three times. If you are a tech, reply back for possible reset procedure. No guarantee though.

Installing JVC KD-R740BT in 1997 Ford truck, keep getting "miswiring, check wires and reset" message

Check speaker wires. All four speakers must be independent. Means no shorting to chassis.

New System Just out of the Box and the very first time I turn it on it checks for all the DVD's and then "Protector Puch power" Message. I check all the wires and Not sure how to do test tone as every time...

Straight to power protect mode indicates crossed wires somewhere or otherwise miswired system. Disconnect all the speakers and try to power on to see if it still goes into protect mode.

If it does, read the manual for troubleshooting tips, or return the unit as defective.

If it does not then replace the speakers one by one until it returns. Check the wires going into that speaker, that speaker may be defective or you may be wiring it wrong.

Subwoofer instalation

Even if your JVC doesn't have outputs for a subwoofer you can hook it up with the a speaker wire to RCA converter. You just spice your rear speaker wires to this device then connect RCA's to your amp. I've used them before... works great.
