I need the code for the stereo it's a ford ba falcon 2004

When you disconnect your battery and then reconnect it again, it disables the radio. This is an anti-theft protection for your car radio.
The enable your radio the activation code is in your vehicle owner's manual. If you do not have this code you need to go to your Ford service centre and get them to enter this code for you.

My stereo sysytem is a mini stereo: serial number 10200055. It currently says "protect", what is this and how do we return our system to normal operations?

Hi there,

When the word PROTECT appears on this display, this means the unit has detected a critical fault which could potentially cause harm to your stereo system.

The most common cause is a short circuit somewhere - something even as simple as loose speaker wiring could cause a short, triggering the Protect message.

You will need to determine if there is a possible short somewhere, so I recommend you start by firstly turning power OFF, disconnecting all speaker wires, then turn unit back ON.

Operate the stereo (without speakers) and turn volume up:
  • If Protect message appears when turning volume up, then stereo unit itself has an internal fault
  • If no Protect message appears, then suspect the speakers may be causing the issue.
  • Reduce volume and turn unit OFF
Re-connect speakers (ensure the connections are secure), turn unit ON:
  • If turning volume up triggers the Protect message again, there is an issue with the speakers or connections

Hope this helps.....

I have recently receieved No Audio from my SA-DX940 stereo. Is there something I can fix myself to help avoid destroying the stereo completely? Thanks, Scott K.

It is possible that the amplifier had encountered a fault with a higher current drain which had triggered it to a protection fault condition. The fault can be your output drivers- the MOSFETS/IC's fitted for both the channels, Use a meter after disconnecting to check for short in the drivers. Disconnect the positive and negative voltages to the output and see if the protect changes. Even a fault in the preamp stages that drives in high current into the output can shut the Amplifier. Sometimes this can be a noise like a HUM or HISS before the protect works. Faulty capacitors in these circuits also can cause similar issues and needs close observation.
You need to confirm and replace the specific stages or outputs. If not there can be issues in the mother board, maybe the protect circuit by itself is shutting off due to a faulty bias , maybe a leak in any voltage/current sensing circuit. Also disconnect the speakers and test, if the protect is off then check for short on the speakers.

Bought the stereo 6 months ago, now the speakers won't work!!!! Please help!

Hi, when a speaker does not work, you might need to do some troubleshooting tips to know exactly where the problem is .

First you will need to test the speaker cone if it's working properly by using an AA battery and two wires to make sure the cone is working..

Connect one of the wires to the Positive side of the speaker, and the other on the Negative side, And after that use the battery to hear if the speaker cone will make a click sound.

If it doesn't make a click, that means the speaker cone is Bad, you will need to replace the speaker cone,
But if there is click from the speaker cone, that means the speaker is Ok, and you might need to trouble shoot your stereo to be sure if the sound IC chip is Ok in the stereo..

Hope it helped..

Remote control won't work

Could need a new ir sensor or repair solder connections on the display (ir) board. You can check that the remote is putting out a signal by viewing it with a camcorder, turn the camera on look through the viewfinder and point the remote at it push a button. If it is working you will see a flashing light on the remote.

Is it possible to install a car stereo without disconnecting the battery cable? I have heard someone mention a harness system where the battery does not have to be disabled for installation. Is this...

Yes, it is possible. There is no "special harness" that allow this to be done any easier or safer. If you have a proper wiring harness for the radio that doesn't expose any bare wires or involve cutting up your car's original wires, it's pretty safe to do. You just unplug the old radio and plug the new one in place. But no matter what kind of wiring harness you have, it's always better and safer to disconnect your battery to keep anything from shorting out.

The battery in my car died and when I jumped it and got it started again, the sterio was asking for a password. It's a used car...I have no idea what the password is. Anyone know of a default code or...

say if your car was a Holden, ring up Holden and just tell them you put a new battery in and your radio is asking for a pass word and they will give it to you..

hope trhis helps

1998 beetle installing new radio but yellow and red wires always hot even with ignition off

i believe you are supposed to disconnect the negative on your battery, but only if you have a memory saver plugged into your cigarette lighter as to not lose any vital computer settings. then replace your stereo and plug the negative back on to your battery and remove the memory saver.
I've been researching about replacing the stereo because mine has fallen apart and i've just ordered a new one plus the ipod connecting kit.
