Hello there,
Here's the Owners Manual PDF(includes wiring diagram) from Alpine's site:

http://vault.alpine-usa.com/products/documents/OM_CDM-7854.PDF

The Wiring Diagram is on 'document Page 16'... which is Page 18 of the pdf file.
Anyhow, the wiring diagram is in there.
I hope that works for you...

While the clock time is displayed press and hold the CLK button for at least three seconds,the time indication will begin to blink,press the H button to adjust the hours while the time indication is blinking,press the M button to adjust the minutes while the time indication is blinking,the time indication will stop blinking after approx. 5 seconds after the last adjustment is made,the time will automatically be set.

The most common reason you would loose the presets is if the yellow wire from the radio is not connected to a constant voltage source. If it is connected to a source that only gets voltage when the key is turned on, you get the problem you are having. That yellow wire is for memory.

If the yellow wire is getting it's constant voltage source, then you have an internal electrical problem that would need troubleshooting by a professional technician. The battery being disconnected and then reconnected should not cause this problem by itself, but it is possible that the radio may have gotten a surge of voltage somehow and caused a failure of some electronic component or maybe caused a circuit trace to burn up.

Since the radio works and the only problem is the memory is not working wold indicate that the yellow wire is connected to the wrong type of voltage source. It is possible that it may be an internal problem of the radio, but the more likely thing is the yellow wire.

worked just fine

check the in-line fuse behind the radio

Blown audio output IC, possibly from miswiring speakers, or accidentaly shorting out one of the speaker wires. It will need to be repaired, or replaced.

That because you connected the wrong remote wire to the amps.The BLUE (only) wire is for the pwr anntena, that is the one is connected to your amps right now.
You just need to switch the blue wires,you have to connet the blue w/white strip to the amps.

1. Mechanical Issue: There might be a mechanical problem with the disc drive or the eject mechanism. It's possible that a part is jammed or not functioning correctly.
2. Dirty or Damaged Disc: If the disc is dirty, scratched, or damaged, the player may have difficulty reading it and thus not ejecting it properly.
3. System Error: There could be an internal error within the player's software or firmware causing it to not recognize the disc properly or to malfunction when attempting to eject it.
4. Power Issue: Sometimes, power-related issues can affect the functionality of electronic devices. Ensure that the player is receiving adequate power and there are no loose connections.

Here are some troubleshooting steps you can try:

• Turn off the player and then turn it back on to see if it resolves the issue.
• Try ejecting the disc using the manual eject button (if available). This button is usually a small pinhole near the disc slot. You can insert a paperclip or a similarly sized object into the hole to manually eject the disc.
• If possible, try using a different disc to see if the problem persists. If other discs work fine, then the issue may be with the original disc.
• Check for any visible obstructions around the disc slot and remove them if present.
• If none of the above steps work, you may need to contact Alpine customer support for further assistance or consider taking the player to a qualified technician for repair.
