Question about Car CD Changers

1 Answer


It says in the instructions to hook the black to ground, the yellow to the battery lead and the red to the acc power lead. I do not have an acc power so I hooked the black wire from the radio to the ground on the battery side and the yellow to the hot side of the battery. The radio will not turn on. The fuse is ok and this radio is new. Any ideas? Thanks

Re: Panasonic CQ-C1335U CD/RADIO FOR AN AUTO

What kind of car do you have a Chevy by any chance?? Any way that red wire needs to see 12 volts in order for the radio to turn on. But this is the wire that should get power when the key is turned on NOT directly to the battery. By the way, If you wires to the battery make sure that you have a fuse no more than 6 to 10 inches away from the battery. You should no matter what make you have be able to find a constant 12 volt for the yellow wire and a ground for the black in the dash. Hit me back with year make and model and I'll let you know how to find some ignition.

I want to switch the power on my car cd player away from the starter, so that i have to turn it on and off myself, rather than when i turn the key. how??

Surely you mean that your cd player is connected to the accessory power and not the starter. If you want your cd player to receive constant power then locate the accessory power wire of the cd player(the one that receives power when the key is on) and connect it to a FUSED constant power source(battery). Usually, if it's a three wire hookup it will be yellow, red and black. Yellow (constant power), red (switched power) and black is ground. If this is the hook up then the red needs constant power. If it's a two wire hook up, red (switched) and black(ground), then the red needs constant power.

No power comes on when I push the power button. I've checked the pwer lead to the radio and I have that. Also checked the ground and have that. Fuse is also OK. Any suggestions?

You need three wires to power on a radio
yellow 12v constant
red 12v switch (turns off/on with key)
black ground

Verify these three and the fuse on the back of the radio as well

Hooking up a sony cd changer cdx-434rf I am not

hey, i just found one of these in my garage and im trying to connect mine too.. I found out what the wires do...

black(ground) - any metal part of the car
red (remote) - to a wire that gives 12v+ when ignition is on.
Yello (power) - 12v+ source, just connect this wire straight from + on the battery.
Read this manual for more info....

No Instruction sheet

This should help you!

As for the remote - see if the cable is hooked up to the readio or modulator. If so press the reset on the back of the remote.

dark blue - goes to a motorized power antenna;
orange - goes to the mobile cellphone;
white - front left spkr +
white w/ black stripe - front left spkr -
gray - front right spkr +
gray w/ black stripe - front right spkr -
green - rear left spkr +
green w/ black stripe - rear left spkr -
violet - rear right spkr +
violet w/ black stripe - rear right spkr -

Hope this be what you need. Pls post back how things worked out or should you need additional information.
