Question about Kenwood KRC-479R Cassette Player

1 Answer

No power to CD Player

I painted my dash (needed removal) for the first time. When I put it back in I pulled the radio wires through and hooked up my CD Player. I set the player by the shifter to grab something and it slid into the metal frame under the dash and sparked. I grabbed it quick.
Now my player doesn't work. I checked and changed all fuses even though none were blown. I bought a test light and touched it to all the wires, the only one that had power was the yellow which I think is the battery.
Some people say i might have shorted my ignition wire. I have no way to hook this up to any other car to see if it's the cd player. The ignition with the key turned though should light the test light correct? There shouldn't be just one wire that activates the light?
 Any opinions?

Hi Allenr,
The red wire should light the test light all the time.
The yellow wire should light the test light only when ignition is on.
the black wire should be tied to the body of the car. Red and yellow should be only wires with power to light test light,
you have blown fuse if the red wire is not lighting the test light.

I'm putting panasonic cq-c1103u player into 2001 corolla using an adapter plug. I have all the wires connected from plug to player harness, but the is 2 wires left over from the plug, the blue power antena...

unless you have a power antenna or an external amp, all those are extra wires. just cap them off. the orange wire is only used if the radio has an illumination feature that allows dimming on the radio. it is not needed to see the radio. DO NOT connect the blue/white from the radio to the orange of the harness. whenever you turn the radio on it will send 12V to your cars illumination circuit. this could damage your lights, dash lights and maybe the radios output.

How do i hook up my amp power wire to my panasonic cq-rx100u

Your power amp wire (positive (RED) ), should be hooked up directly to your battery....THe ground wire should be anchored to a bolt in your trunk (the short the distance the better), Make sure ground is getting a good bite on metal (no paint etc)....Only thing you should have hooked between your amp and radio is the rcas and your remote wire (blue).

I am having trouble getting power to my new cd player. I have the orange battery wire hooked up, and also the ground wire is hooked up, and there is a red wire on the cd player that is a Ignition wire....

2 wires for power- one that is ALWAYS connected (remembers time, preset stations, etc.), and the other one you hook up to your ignition circuit (allows your radio to come on only when the key has been turned to ACC or RUN).

When you have wired this correctly, your radio will only come on when the ignition key is in ACC or RUN, and will ALSO remember the preset radio stations and the time, etc., when the key is turned off then back on again.

If you look at your fusebox, look for an ACC (accessory) junction that you can tap into. Also, don't forget that it's important to put a fuse in any wire you connect to a 12v+ source; don't rely on the fuse you are tapping into.

Hope this helps.

I install a radio it dont keep a memory

Pull the radio back out. I bet you hooked up both power wires (red and orange or yellow) to the ignition on hot wire. Orange or yellow depending on the radio usualy goes to the ignition on hot wire and red to a constant hot wire. Check the radio wiring diagram or list. One of the power wires has to go to a full time power source. check the wires with a circuit tester with the key off till you find the constant hot wire (battery power)

Does the amp have a light that lights up when its on? because if it turns off whan you put a cd in that means who ever put ur stereo in has used the power antena signal wire not the amp signal wire, because thay do the same thing but one works all the time and the other only works when the radio is on. hope this helps reply back if you need more help

Wiring diagram

First, goto a store and buy a snap in wire harness and a mounting kit. There are wire diagrams in the packaging. Wire your wire harness into the radios wire harness (everything is color coded). Follow the intructions to install the mounting kit. It should tell you what screws to remove from your dash and so forth. Just remeber were everything goes. Next, after you remove the old radio, snap in you wire harness to the cars wire harness. Then, test the radio to see if it powers up and all speakers are working. Lastly, put you radio in your dash, and put everything back togeather. The number one rule in installation is take your time. If you rush, you will brake something.

It's because the second power wire needs a constant hot feed. The yellow wire from the wire clip in the back of the stereo is your constant, so you need to find a powered wire coming from the bundle of wires in your dash that will produce electricity both while the car is on and while the car is off. Use a simple ground/light current tester to find the wire in the dash or go buy a Haynes Manual for your car and consult the wire diagrams in the book. Once you get that constant current hooked up, your radio will save its memory when you turn off the car. Good luck.

DEH-P2500 Not Working At All

i have the same unit i put it in my jeep wrangler had problems as far as which 2 hot wires need to be hooked up. finnally figured it out. take it out hook up the hot wire and ground straight to the battery, it should come on if it does come on then you have a problem in the wiring from the dash, to make sure the wiring in the dash is good you should check your fuses first, then do a continuity test with a volt meter to check for a break in the wire wether it being ground or hot. weed out the simple problems first. if your head unit does not come on from direct hook up to the battery then the problem exist in your head unit
