Nick i believe that you have a simple ground loop problem. To fix that you'll need to run a ground wire from your EQ to the body of the car. (the shorter the wire,the better the ground)
Find the ground wire (black wire) coming out of your EQ. Splice a wire into that wire,and then connect that wire to the black wire coming out of your Head Unit,and that should solve your problem.
Either the radio is bad out of the box (Very possible with the BOSS brand) or you car has factory amplifiers that need to be turned on. This is aaauming ther sound system played prior to the installation of the new radio. Most vehicles you can power up the amplifiers simply by connecting the BLUE remote turn on wire in the harness, but can get tricky in some vehicles.
Post the year make, and model of your car, and I can shoot you some odds/info about factory amplifiers.
If blank, or some segments missing, it can be the connector to the main board, (usually a ribbon) or it can be the rubber connector electrode that links the lcd glass to the circuit board connectors. If you have the inclination, and patience, and a steady hand, and are confident... (alot of "and's" there ;-) you can take it apart, remove the LCD display, take it apart (usually by bending a few metal tabs, the thing will come out, and if you gently separate all the layers it will come apart fairly easy. Then you will see the rubber edge connector that goes to what looks like clear glass (but it actually makes contact there) to drive the segments. What you need to do is gently clean the rubber (both sides) and the gold board contacts (leave the glass display conmtacts part alone) then re-assemble the thing and you may get your display back. This symptom can happen to some LCD displays left in extreme temperature cycle enviorments, or other harsh conditions... or a garage for a few years.. You never know ...
If this does not bring it back, check the cconnectors for dirt (if face is detachable, I don't recall on that exact model if it is or not).
and then go further to the driving circuitry on the board.
As you have indicated there is no sound at all in the out-puts available.What this could probably mean the out put ic is dead.Another thing to remember is to connect the red positive wire to the standby wire which is mostly yellow in color.
The issue you're experiencing with your Pioneer PD-M40 suggests a potential problem with the disc loading mechanism or the sensor that detects the presence of the disc cartridge. Here are some troubleshooting steps you can try:
1. **Clean the Disc Cartridge and Player:**
Dust or debris on the disc cartridge or inside the player may affect proper disc loading. Remove the disc cartridge and clean both the cartridge and the player carefully with a soft, lint-free cloth.
2. **Inspect for Obstructions:**
Check for any visible obstructions inside the disc loading mechanism or around the edges of the disc cartridge slot. Ensure that there is nothing blocking the path of the cartridge as it is inserted.
3. **Check for Proper Alignment:**
Ensure that the disc cartridge is properly aligned when inserting it into the player. Misalignment may prevent the player from recognizing the presence of the cartridge.
4. **Try a Different Disc Cartridge:**
If you have access to another disc cartridge, try inserting a different one to see if the issue persists. This can help determine whether the problem is specific to the cartridge or the player itself.
5. **Power Cycling:**
Turn off the player, unplug it from the power source, and wait for a minute or two. Plug it back in, power it on, and then attempt to insert the disc cartridge to see if the issue is resolved.
6. **Test with the Lid Open:**
Power on the player with the lid open and observe the disc loading mechanism as you insert the disc cartridge. Check for any unusual movements, sounds, or signs of misalignment.
7. **Lubrication:**
If the player has not been used for an extended period, lubrication on moving parts may have dried out. Consult the user manual for recommendations on proper lubrication or contact Pioneer customer support.
8. **Contact Pioneer Support:**
If the issue persists and you've exhausted the troubleshooting steps, it may be advisable to contact Pioneer customer support or seek assistance from a qualified technician. There could be an internal issue that requires professional attention.
Always refer to the user manual for your Pioneer PD-M40 for model-specific instructions and recommendations. If you don't have the manual, you may be able to find it on the Pioneer website or by contacting their customer support.
Question edited for clarity and 'make, series, model and number' in correct order.
My searches lead me to believe that you have a model that was made for the Japanese home market and only comes in Japanese. The advert for it is in Japanese. No English Manual listed.

Greetings from Mississauga :>D
My research shows it just needs a standard RCA lead to connect. However you realize this is just a standalone CD player and needs an amplifier as well as speakers? It has no amplification of its own, it just puts out an audio signal.
When connected to a Pioneer System Audio Amplifier, the control cables allow you to control the CD Player from the Amplifier remote control as they cable connect to that amplifier. The Line Out connections are for the RCA cable and supply the audio data to the amp.

You just have one small part of a composite audio system.
Regarding speakers, most are 8 ohm. you can spend $50 used or $60,000 for Bowers and Wilkins Nautilus. I have a pair of Wharfedale Linton speakers that I bought from the UK factory that you can have for $450 CDN :>) Top of the range.
