how do you hook up a Sony cdx-c480 car stereo?

Question

Hi, it has red, yellow, dark blue, light blue and a bunch of speaker wires. If I hook up red and yellow to +12v and bk to -12v a rattling sound like a stuck cd happens but the faceplate doesn't light up. Nothing else connected. Any ideas? It's a free-bee but it looks like it was a pretty decent deck at one time. I read the light blue is a mute you can connect to a cell phone that turns off sound to the player. Thanks and keep up the good work.

Oh boy, i hope you mean "red and yellow to +12v and bk to ground" .Thisis being done in a car right ?, "red and yellow to +12v and bk to -12v" could mean a potential difference of 24 volts which would wreck theunit.The red wire is supposed to be connected to the "Acc" or accessoriesterminal which is basically switched +12v coming via the ignitionswitch. Yellow should go directly to battery +ve., Black to ground.

No, this is a sort of "standby voltage" it's needed for keep in memory stations and hour, but it's also needed during normal work. Connect this to normal +12. Connect the normal +12 to the ingnition key... or if you want radio also when engine's off, connect +12 STBY and +12 POWER toghether to the battery.

No, it's a 300mA output to the motor of the automatic antenna. If you don't have one, leave this alone.

I removed it from my old car... it has a "10" fuse, maybe 10A ??? To test it, connect RED+YELLOW to +12V and BLACK to ground.

Maybe there's a problem with the internal psu/filter... but if i didn't have in my hands the unit i can help you, sorry.

Thank you all. Yes, I meant the negative pole of a 12v battery, not

-12v. Me culpa. So,... from your pinout my hookup should have lit the screen with digits, correct? I reset the button inside the faceplate. Is there a diagnostic button combo for this type of thing? I get 4.89v on some of the faceplate pins with the faceplate removed. no 12v reading.

this is to keep a clock and the radio stations from resetting?

what's a remote? Do I need one for the unit to operate? Will it not turn on without it?

check.

wow, 40watts, feel the beat.

Thanks I got an XR-1300 for free too. No action there either. I fount a 4A in the redline fuseholder. I'm used to seeing 2A or so. Also in the junk pile was a Kenwood RR-500E and an alpine CDA-7839. Any info on these would be great. Non of these lite up because the output stages were shorted at some point? Is that the most common source of failure for these things? Why would I hear something try to motor but get no LED? Thanks again and bye for now.

Normally yes - if you don't hook it up, the radio will probably work. However I have seen one Delco radio where this line seemed to do a lot more than just keep the clock and memory working; you had to hook it up for the radio to operate. If there is a "big" fuse (say, 3 A or more) in this wire and a "small" fuse (say, 1 A or less) in the red supply wire, then that's another clue that the yellow wire is powering most of the radio and the red wire is just telling it when to turn on and off with the ignition key.

Usually this is used to turn on a power antenna or external amplifier. It should have 12 volts only when the stereo is on (in any mode, tuner/CD/tape). You usually can't get much power from this line - it's designed to operate maybe a couple of relays, tops. Usually it doesn't affect anything if you leave this wire disconnected.

You might try sequencing the "supply" and "memory" wires like they would be in a car. In other words, hook up the black (ground) and yellow (memory) wires to the battery, but leave the red (supply) wire disconnected for a few seconds. Then hook up the red (supply) wire to the battery.

You may be able to get more hookup information in rec.audio.car . Once you're sure it's hooked up right, if it still doesn't work, then post back here.
