Pioneer CDXP1280 12 cd changer. Power to changer, no operation

I unplugged the changer and tested the power to the changer. One side of the wire was hot. Are both sides of the supply plug supposed to be hot? I have no operation of the changer. This would be the 3rd one in 3 yrs. Thanks

I Think there are 3 wires to a Pioneer changer??
+12V Battery ( Hot ) on all of the time
Switched +12v ( accessories, or switched by the radio only when it's on,
and Ground (Chassis Earth)
I think there was 2x orange and one black wire
Make sure that there is a good earth to the changer. Use a multimeter on ohms between a good earth point on the car and the cd changer or the black wire.

If you disconnect and reconnect all poer to the changer, you may hear the motors whirr for a short time as the mechanism resets, but cant be sure.
Hope that helps

Premier car stereo no longer reads USB drive

Have you re-formatted the drive at all, added any new files to it? To test the unit try a new USB drive with only 1 MP3 track on it. Let's make sure the unit can read that so we can eliminate a hardware issue with the deck.

it could be the interface is bad. i just tested on with brand new changer..and it did the exact same thing yours did. its either the interface or the factory radio is bad. i would think the interface.

I have pioneer KEH-P6900R-B car stereo and i don't know how to connect it to speakers and power

You have to first diffentiate the power from the speakers. The ORANGE, RED and BLACK are the power. Connect the RED to continuous supply of the battery which is available in the accessories socket, the Orange to the switched power which is also available in this socket. The Black should be connected to the best ground available, check all these using a good meter. Next greys, the greens, one with the red mark on the wire to be connected to the positive of the speaker , the black mark to the negative. repeat this for allthe other wires and test. Now if you think that on balancing to one side the bass is better, reverse one side of the polarity of the speaker.can be the front speakers or the rear. I think you can get this right. Good day

I can not hear any audio

If you have the correct head unit, and assuming the cable is in good condition, the it should work. Although I do remember some Pioneers needed Permanent 12V+ and ground hooked up in order to work. If this is one of those, on the changer side there should be another white plug next to the changer cable with two or three wires in it. This should be the power feed wirs for the changer. I need more info to confirm.

its simple that model may be equipped with factory amplifier and cannot transmit to speakers unless bypassed and wired directly to speakers after amplifier but if unsure go to and get help! or call local audio dealer. Also if you purchase wiring and installation kit it will bypass that.

Most common for all car Stereo wire color coding are:

Solid RED wire = +12V
Solid Black wire = negative ( - )
Solid Yellow wire = +12V (power ON /OFF) can add additional toggle switch for switching on and off the car stereo

Solid blue wire = Power antenna

the rest of the wires are for car speaker having positive and negative polarity.
note: for the speaker connection wires, all the solid colored wires are positive side (+) of speaker. those solid colored wire with stripe black line are for negative side (-) of the speaker
