Panasonic cq-c8303u Car stereo problem

I recently just purchased a brand new panasonic cq-c8303u to replace the old radio in my 92 geo metro hatchback. After i had removed the old stereo i found the stereo wiring in the car had been cut and was just a jumble of loose cords. I was able to obtain a wiring diagram for my car and i hooked up my panasonic HU to the car. Unfortunatly it didnt work. I checked the stereo fuse in the car and it was fine. Does anyone know why the HU does not turn on? Your help is much appreciated. Oh, i know the HU does work because if i hook it directly up to the cars battery it turns on

Re: Panasonic cq-c8303u Car stereo problem

There is for sure a hook up problem my friend. There should be a memory wire that always has power to it even when the car or the ignition is off. Then there is a switched type wire that only comes on when the cars ignition is on. Check both of these wires in the car. Check the car wiring diagram to confirm this. To confirm the wiring in this vehicle, I Good Luck with this install. And if all else fails, don't take a chance and blow out the unit, take it to a pro to be installed. Good Luck found the right wiring diagram for your car. Confirm this wiring diagram with this one you have. Go here:

I took my panasonic cq-c8303u out of my jeep and put it in my civic hooked all the wires up right but no power to my deck whats could the problem be?

Check the in line cylinder fuse for the radio, cause they blow easy. Also, check the radio fuse under the dash or wherever your fuse box is located. Make sure you solder the connections for a good contact, cause just wrapping electrical tape around the wires will cause you problems down the road when you go over bumps.

Panasonic CQ-C8303U. Hooked up an amplifier and it works with the radio but when i put in a cd the amp doesn't work. the receiver just plays with normal sound.

Verify your wire connections are correct. Keep in mind that if your amp is hooked up to the radios power antenna wire this is the problem. When you insert a cd the radio is designed to lower the antenna. If your amp is hooked up to the antenna wire the radio is shutting off the amp when you put in a cd Panasonic does this on most of all their units. You may have to hook your amp up to a separate switch to turn the amp off and on or hook it to your ignitions acc wire, if you hook it up to your ignitions acc the amp will stay on as long as your key is on even if you turn off the radio.

I have a Panasonic CQ-RX400U and I need to hook it up to a 1992 Ford Taurus and I need cables to hook it up and the thing that holds it in place in the dash.

I would get an stereo installation kit from Auto Zone or a local automotive audio store. It will come with the surround for the new stereo to fit where the old stereo went, and a wiring harness to hook the new stereo up to and plug into the existing car wiring.

are you running the rest of your speakers off an amp? if so, it sounds like you have the amp remote wire connected to the power antenna wire. on some radios there is an amp remote wire and a power antenna wire. the power antenna wire loses power when not listening to the tuner (radio). usuall there is a solid blue and a blue with white stripe. the blue with a white stripe should be amp turn on.

Sorry, there's no way to repair the CD, if faulty. Try looking for a "reset" a VERY tiny hole somewhere behind the "door", on the face of the radio chassis...Using a paper clip end push into the tiny hole for a few seconds, ignition/radio on...If you can't find a reset...take it to a friendly local car stereo shop and ask them to diagnose the problem ($40).
Good Luck

I have the panasonic cq-c8303u radio and i would like to hook up the ipod to it. any tips?

You need to get the Direct Cable for iPod® (CA-DC300U) from panasonic. This allows you to plug in and control your ipod from your headunit. There is also the expansion module (CY-EM100U), however I am not sure if this is necessary if you have the Direct Cable. The Direct Cable might plug directly into the back of the headunit without the need for the expansion module. Check with the company before purchasing one or both. If the direct cable requires the expansion module, then get both, however, I think the direct cable works independent from the expansion module. Again, contact the company about this. The expansion module also lets you plug your ipod as well as other devices into your headunit, however I don't think it allows you to control them via the unit. I think if you want to control the ipod from your headunit, you just need the Direct Cable for Ipod®.

Hi again,

My apologies, missed the connection. Now I remember, must be really getting old.

Back to your concern, which fuse pls? the 15 amps for the Panasonic or the amp"s fuse.

Incidentally, even if the speaker wires were wired incorrectly, that would not cause the fuse to blow. The only way the fuse would blow is if the unit was connected with the polarity reversed, even just once. Internally, most units have a reverse protection diode and/or regulator that would short circuit itself. Thereafter even if it were wired correctly to the battery, the fuse will always blow.

Looking forward to hearing from you.

No sound from CQ-1305U car CD/stereo

You may have one of this two problems:
One of the speaker wires is grounded to the chassis.
Or your car may have a factory amplifier between the radio and the speakers.
My suggestion is to rewire the speakers lines
