Loose connection or your power cable and earth cable to your amp are not a heavy enough gauge.
Speaker Fried, is my Amp toast too?
You are sending TOO much power to the speakers, Replace the speakers and then get a much smaller amp that is within the ratings of the speakers. ACTUALLY you should get an amp that is aboout 1/2 the total rating of the speakers.
You should ALSO procure a sound meter to verify the sound level is within safe limits. If you insist upon abusing your ears with too high a sound pressure, be ready to buy hearing aids at a VERY young age.
You also need to know that the enclosure of the speaker plays a part in keeping the speaker from tearing itself to pieces.
MANY of the auto sound system installers are hacks that don't do it right and you see what happens to your expensive equipment!
Using even a Radio Shack sound meter properly will protect your preciuos hearing for later life.
If the amp is in protect mode, it probably has shorted output transistors. To eliminate other possible problems, do the following. I'll assume that you've checked the amplifier's on-board fuses.
With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp (not on the point where the ground wire connected to the vehicle) and the head unit on (so the amp will have remote voltage applied), touch the red lead alternately to the B+ and remote terminals of the amp. If the voltage is below ~11 volts, you need to check the wiring feeding whichever line is too low.
Disconnect all speaker wires from the speaker terminals of the amp and disconnect signal cables from the amp. If it powers up, the wiring needs to be checked. If it remains in protect mode, the amp almost certainly has shorted output transistors and will need to be repaired.
We have car audio that requires code, do you know the options how to unlock it?
If your car audio system requires a code to unlock it, there are a few options you can try:
Check the user manual: The user manual for your car audio system may contain information on how to unlock it if a code is required. Look for a section on "security" or "anti-theft" features.
Contact the manufacturer: If you don't have the user manual or can't find the information you need, you can try contacting the manufacturer of the car audio system. They may be able to provide you with the code or instructions on how to unlock it.
Try common codes: Some car audio systems use a default code, such as 0000 or 1234. Try entering these codes to see if they work.
Reset the system: If none of the above options work, you may need to reset the car audio system. This will erase any saved settings and data, including the code. The process for resetting the system will vary depending on the make and model of your car and audio system. Check the user manual or contact the manufacturer for instructions.
Working on a Rock-Ola 488 Jukebox. Looking for a block diagram of power distribution
Unfortunately, I do not have access to specific diagrams for the Rock-Ola 488 Jukebox. However, a typical power distribution block diagram would show the power source, such as the power supply, and the different branches of distribution to various components. These could include the amplifier, control circuits, motors, and lighting.
In your case, since you only have the power supply and power amp, you could start by tracing the power wires from the power supply and identifying which wires connect to the power amp. Then, you can look for any other components in the jukebox that require power and trace their wiring to the power distribution network. This should give you a general idea of how power is distributed throughout the jukebox.
It i stuck on the cd button and I can not get it to change
If your device is stuck on the CD button and you're unable to change it, try the following steps:
- Check the device's manual: First, consult the manual for your device to see if there are any specific instructions for changing the input source. Some devices may require a particular button sequence or menu selection to switch inputs.
- Power cycle the device: Turn off the device and unplug it from the power source for a few minutes. Then, plug it back in and turn it on again. This may help to reset the device and allow you to change the input source.
- Check the remote control: Ensure that the batteries in the remote control are working properly and that you are using the correct remote control for the device. Some devices may require a specific remote control to change inputs.
- Try a different input: If you're unable to change the input from the CD button, try selecting a different input button such as the radio or auxiliary input. This may help to reset the device and allow you to change the input source.
- Contact the manufacturer: If none of the above steps work, contact the manufacturer for assistance. They may be able to provide additional troubleshooting steps or suggest repairs or replacement options.
Hopefully, one of these steps will help you resolve the issue and allow you to change the input source on your device.
BEOSOUND9000 - When BEO4 is set to 'CD' 'Shift 90258' for test mode, when I then press '72' the message on the BEOSOUND 9000MkIII states 'Wrong SRC/TM' even though It worked at the start of the repair
The message "Wrong SRC/TM" on a BEOSOUND 9000MkIII when pressing '72' while in test mode (Shift 90258) and set to 'CD' could indicate that there is an issue with the source selection or the test mode itself. To resolve this issue, you can try the following steps:
- Check the source selection: Make sure that the correct source (CD) is selected on the BEO4 and that it is functioning properly.
- Check the test mode: Verify that the test mode has been activated correctly and that the Shift 90258 code has been entered correctly.
- Check for firmware updates: Make sure that the firmware on the BEOSOUND 9000MkIII is up-to-date. If there is a firmware update available, install it to resolve any issues with the test mode.
- Factory reset: If the above steps do not resolve the issue, a factory reset of the BEOSOUND 9000MkIII may be necessary. This will restore the unit to its original settings and resolve any software-related issues.
If these steps do not resolve the issue, you may need to seek further assistance from the manufacturer or a professional repair service. It's important to follow the manufacturer's instructions and safety guidelines when attempting to repair or troubleshoot your system to avoid damaging the unit or causing potential harm.

Xtc No power but fuses are good what is the problem?
A possible issue could be a faulty power supply. In order to confirm, you can try plugging the power supply into separate power source to ensure that it is capable of supplying power to the unit. Additionally, the speaker connections may have become disconnected, so it would be beneficial to check the wiring in order to ensure that all connections are properly secured.
Why won't my front speKers play on my avh 200e x?
There could be several reasons why your front speakers are not playing on your AVH 200EX. Here are some possible causes:
- Wiring issues: Check the wiring connections between the receiver and the front speakers. Make sure that the wires are properly connected and that there are no loose connections.
- Speaker settings: Check the speaker settings on your receiver to make sure that the front speakers are enabled and set to the correct size and frequency response.
- Balance and fader settings: Check the balance and fader settings on your receiver to make sure that the front speakers are not set to a low level or muted.
- Amplifier issues: If you have an external amplifier, check to make sure that it is properly connected and powered on.
- Speaker problems: If the front speakers are still not playing, there may be an issue with the speakers themselves. Check to see if the speakers are damaged or if the wiring connections are loose.
If none of these steps resolve the issue, you may need to consult with a professional or contact the manufacturer for further assistance.
Radio won't turn up. Very low volume out of speakers
It sounds like you are having trouble with the volume on your radio. This could be caused by a few different things. To troubleshoot, first ensure that the volume knob on the radio is turned up to its max. If the volume is already turned up, then you should check the speaker wires to make sure they are connected properly and not loose or frayed. If the wires are secure, then you should check the volume control on your amplifier to make sure it is not set to a low volume level. If the amplifier volume is already set to a high level, then the problem may be with the radio itself and you may need to contact a professional for extra help.
