Question about Sony CDX-GT300 CD Player

1 Answer

No power!! My radio has been playing fine but just recently i've noticed that when i've been going over even small bumps the radio has been cutting out, then coming back on. Today, i went over a bump and the radio cut out and hasn't come back on. I've checked all the connections in the back and they are fine. What could be the problem, i'd rather not pay alot of cash to a garage for a simple solution. Thanks.

Check the fuse box, maybe the fuse burned.

No sound from the cd and extended media but have sound from radio

If you have an amplifier connected to the radio, make sure the amp remote wire is connected to the blue/white wire and not the blue wire of the radio. The blue wire is for power antenna and is energized only when tuner is playing, not when cd or ext media is played, and therefore will shut your amp off when playing those sources.

No sound from deck

Are the speakers connected directly to the JVC? If so, all four speakers going quiet could be bad soldering on the radio. If the speakers are not connected to the radio, then check the blue/white wire that turns on the internal amplifier.

Crackling and scratching

Your speaker may be blown take out the speaker that is hooked up and attach another one a house speaker would even work, and i bet your speakers are blow if not check the wires and make sure you have them connected properly if not check the wires going to the harness and to the speaker and if not i think the radio is fried you can also take a long speaker wire take radio out the dash and run it to the speaker if it does still the radio is fried take it back before 90 days is up!

My Kenwood KDC-325 would frequently cut in and out, the sound would go off randomly while driving, and I would have to go over a bump in the road or a pot-hole and the sound would come back on. Recently it...

High chance that the fault was not came from the wiring but in the unit itself. This kind of symptoms is an indication that there is a bad solder joints (cracked, dried, cold solder) in the sound output circuitry. This circuitry is responsible for producing sound and feeds to your speakers. Since the unit is totally muted(no sound), this circuitry is disable due to said reasons. The only way to back it from normal operation, it needs to take apart and re-solder the joints in this circuitry. You need an assistance of a qualified technician to do this job.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

Over the bumps sound cuts off

are you listing to cd or everything? do you have amplifiers? i found that when my pre outs were going bad my hole radio would cut out when i hit bumps. also some decks dont do well on bumps with their cd players. maybe try straping all of the wires in the back to a sable source on the car to reduce the stress on the plug ins when hitting bumps.

1991 buick park avenue. new radio isnt wanting to power up (no power)

there is a wire on the back of your radio that is red and it has to be hoocked up along with the yellow and the black, you have to hook that red wire up to a power source as well that is the wire that turns the radio off and on with your key.

Radio shuts off at volume of 16 or more

Maybe a protection component cutting in.
If you have speakers that are too powerful for the radio it may shut down to protect the amplifier from overdriving the speakers. That produces too much heat in the amp chips/transistors and they either have a overload cut out protection circuit or they burn out.
Even if the speakers are the stock fitted ones the wattage could be bigger than the amp in the radio can handle.
There's probably no way of knowing how powerful the speakers in the truck are but you could try the radio with another set.
Max 50 Watts for that radio. If you don't have the manual for it, it's available here:

Read the Manual on Page 2 or get it from:

Just make a reset with a pen or something else.
This should solve the problem.
