Ive got a JVC CD/MP3 stereo that I pulled out of my car after I totaled it. My VanHalen cd is stuck inside, and I want it out. I currently have emulated a power supply of 12v (regulated through an AC adapter), ground, and a toggle switch to take place of the accessory from the ignition.
My issue is, the power supply(s) that I am using are only pushing 15.7v. The unit itself is lighting up, yet there is still not enough electricity to completly power up and use the device.

*There are two power suppies... 12v & 3.7v.
They are not putting out Ma's but rather aperage itself for a total of 3.5A

Your adapter may only put out milli amps, not suitable for playback for sure, not even for ejection motor. Hook up to a battery instead of the dingy transformer.

It's the amperage of the power supply that matters. Not voltage. Possibly, your power supply is not able to deliver the current necessary to drive the stereo. If that's the case, you'll have to find another power supply.
I have no idea what the current requirements would be for your stereo, but I would think that a power supply with at least 2 amp capability would be sufficient.

Instead of the power supply, why not just use a car battery? Hold the hot wire to the post and another to the case to ground it. If that doesn't do it, then you have another problem.

1. 12v should be sufficient
2. Are the power supply(s) outputting dc volts
3. power supply(s) need to be sufficient power rating you need at least 1amp to run a car stereo
4. if all else fails connect it to a car battery

Time to get back to basics - look up the Ohm's law, and answer your question yourself. Using gray matter is what differs us - well, some of us anyway - from Neanderthals!

just find a friends car and ask to take out theirs and put that in for a sec to get it out.
