You may need to add an ignition noise line filter to your DC power supply. These can be purchased from any electronics store. Your problem is ignition noise or alternator noise caused by dirty brushes within the alternator. A line filter will take care of this.

Hi Greg, I'd say you have a bad audio output IC, generally this will take out the fusable resistor that feeds the output stage, you should be able to find a part number on the IC, do a pin out and check between B+ and ground pins with it in circuit and see if you see a short. I don't know if you can find a service manual for it but hopefully you wouldn't need one

Question edited for clarity and typos. The first thing with CD Ejection issues is to try a CD Cleaning Disc. It has brushes to clean the laser optics. They always fail on the low power tracking laser. When it fails self test, it ejects. also First unplug power for at least an hour, then press and hold the power/on button while plugging back in, and keep holding for another 60 seconds . Here is the Service Manual https://www.manualslib.com/manual/683358/Panasonic-Sa-Ak87.html https://www.google.com/search?q=panasonic+sa-ak87+cd+keeps+ejecting+disc ....

I'm sorry, but wiring diagrams for specific car audio systems are not readily available to the public. These diagrams are usually confidential and used by authorized repair technicians only. If you need assistance with the wiring of your Panasonic CQ-C1100U car audio system, I would recommend reaching out to the manufacturer or an authorized repair service for support. They should be able to provide you with the information and guidance you need to properly install and wire your system. It's important to follow the manufacturer's instructions and any relevant safety guidelines to avoid damage to the system or potential harm to yourself or others.

It sounds like your SA AK 133 5 CD changer has some issues. The AM radio band not turning on could be due to a faulty antenna, a problem with the power supply, or a software issue. To resolve this issue, you should check the antenna first and make sure it is connected properly. If the antenna is connected properly and the issue persists, you may need to check the power supply or contact the manufacturer for assistance. The issue with the CD not ejecting could be due to a faulty drive motor or a faulty eject mechanism. To resolve this issue, you should check the drive motor and the eject mechanism and replace them if needed. The issue with the tapes not working could be due to a faulty cassette player mechanism. To resolve this issue, you should replace the cassette player mechanism.

This indicates that the CD player is ready to receive a signal from a Bluetooth device. To connect your device, you will need to enable the Bluetooth setting on your device and then select the "PANASONIC" device from the list of available Bluetooth devices. Once the connection is established, the source button should stop flashing and the audio from your device should play through the car audio system.

Hi, Check that the equalizer settings are what you want when you are playing audio using a BT connection. The user manual states that the settings are memorized for each source i.e. tuner, BT and CD, which I assume means that it can be set differently for each input type to suit what you want
