Remote lead voltage

Should I see 12vdc on the blue remote wire from my CDA 7875 while turned on? My AMP will not fire up anymore. I read about 1/3 of a volt.
Is this lead fused from factory?

Thanks
Bob

I would say it is. Did you disconnect the blue lead from the amp then measure the lead for 12v? I just hooked one up for my son and the blue lead was the 12v that turned the Switch Mode Power Supply in (SMPS) the Amp, now, it's only present when you turn the radio on, it's not full time. If all this is done and you don't have 12v on the blue lead, I would look for a in-line fuse close to the radio. Now, if that fuse is open I wouldn't be surprised if the amp is gone also. If it was under 150.00, I would'nt have it repaired, just buy another one. My son was forced to do that because the parts were almost 1/3 the price of the amp, at my cost! Keep in touch.....

Eclipse cd 3200 i recently installed in in another car. Now the radio works fine but when the cd player is on no sound comes out


Are you running your audio through an amplifier? If so, it sounds like you are using the blue wire instead of the blue/white wire to turn your amp on. The blue wire is power antenna remote turn on and turns off when leaving tuner mode. The blue/white wire is amplifier remote turn on.

It reads the cds but there is no sound


are you running audio through an amplifier? if so, you may be using the wrong blue wire to turn the amp on. usually the amp remote wire is blue/white. solid blue is usually antenna remote, which turns off when leaving tuner mode.

I need wiring diagram for pioneer deh p56


Pioneer follows the universal after-market color code, so if your CD player was made in the last ten years or so, the wires should go like this: Yellow: Constant +12VDC (memory) Red: key-switched +12VDC (accessory) Black: Ground Blue/white: amp remote or power antenna output Speaker wires: The solid-color wire of each pair is positive; the black-striped wire is negative. Left front: white Right front: gray Left rear: green Right rear: violet

Pioneer DEH-225 Car Audio


The system remote control is usually a blue wire on your decks harness and it is for an amplifier for a sub or other speakers. It sends power to the subs amp when the deck is turned on. You may need to find the wires coming off the antenna and splice them into the red power switching wire 12v on you decks wire harness. Good luck
