When any radio shuts off wth high volume it is caused by several things.

1. The maximum power output was reached and the unit goes into the self protection mode.

2. The most common reason.... The power transistor has partially failed and will not provide the partially amplfied output necessary.

3. Units with removable face plates vibrate enough to disengage the face plate contacts so the unit shuts off.

4. The speakers are too big for the radio causing it to self protect. (system mis-match)

5. Loose connectors/pins on the radio input and output connections.

6. A poor system ground that is good enough for low volume use but when high power use is encountered the ground is not good enough to carry the amperage necessary.

These are the most comon reasons for a unit to shut off at higher volumes.

It is not always an easy fix troubleshooting this problem. I know first hand as a life long electrician that has the exact same problem with the radio in my automobile. (Mine appears to be a power transistor grounding problem) With shipping to the repair center each way and the flat rate repair cost it would cost as much as a new one!

Thanks for using FixYa.

JVC KD-LX333 car stereo turns on, but then shut off and wont...


TAKE IT OUT AND TRY IT ON A 12V BATERRY AND IF IT TURNS ON ITS GOOD AND IF IT DOESNT IS NOT GOOD. IF IT TURNS ON FOLLOW UR CONSTAN AND UR POWER WIRES AND SEE IF IT HAS A FUSE BOX IN THE BOAT/ CHECK THOSE FUSES. AND CHECK UR BOAT BATTERY TOO CAUSE IT COULD HAVE DIED WHEN TESTING THE STEREO TOO IT HAPPENS ALOT ON BOATS

Losing power


mine does this too, I have the deck on my boat and on land the deck cuts out when a bass line hits or loud music comes in, cuts out at about 20 on the volume level, however, when on the water and the motor is running, my voltage is up to 14 vdc or so.. At this point, I can crank the deck up to 30-37, and it will scream , doesnt cut out or lose power just rocks. I have heard that kenwood decks are competition stereos and require 14-16vdc, but I have never found any proof of this. One thing you can do is order a battery from summitracing.com that runs higher than 12vdc. But then again im just speculating

JVC Car stereo with cd shuts off when volume is turned up


Hi Ithink , you are trying to push too much power to your speaker setup. Your cd, tuner, player, is only go as loud as the volume at half way setting. Your speakers are , probally good ones that want more power, and making your player overheat and making circut protection cut power. I would say, you should use it at 15, and that is as loud as it should be played to aviod distortion and overheating.
I'm guessing max is like 25 or 30, Is that so? You can listen to louder tunes by installing an amplifier. Or if you have an amp in your system it may be overheating, I would really like you to let me know if you have been trying use it at volume higher than half the maxium volume setting, so I know I helped, and you can start looking into power amp's. You can crank it up for good parts, but most players were not made to send alot of juice to good big speakers at high volume level.
Tell me what you think, tooldoc

HELP STEREO CUTS OUT!


ok , ive found the problem with mine. I checked the voltage between the earth wire on the head unit and the battery in the car. I found that when i turned the headunit up to around 17-20 there was up to 3volts differance, which is when it would cut out. So ive run a new earth wire and she's all sweet . Even the cd player works now.

Volume turned up, kenwood shuts off briefly...


I had this same exact problem when my last older Kenwood Marine stereo cooked itself while I had it up loud for a few weekends on the lake. (smelled like it had burned inside). I went out and bought a new Kenwood KMR-550u stereo deck. (I do not have an additional amp). I hooked it up to the exact connections where my older Kenwood stereo unit had been hooked up, as I never had a problem with this for the past three years until it failed after smelling of burning elelectrical. I had chalked the problem up to heavy rain we had one day. Every time I turned up the volume, sometimes up to 27 out of 35 possible, or 29, or 32, the stereo would suddenly shut off as if I had turned it off. After a few seconds the stereo would come back on, but unless I was quick enough to turn down the volume it would do it again right away. Of course on a boat, we were beached in a cove and the engine was not running when I encountered this. I searched the internet finding hundreds of similar complaints and several dozen theories of all types, but only a couple that pointed me towards the power (voltage) idea as the problem. I put a volt meter on the positive & negative wires powering the stereo. I watched as I gradually turned up the volume, the voltage on the power wire gradually decreased from 12.5 volts, down into the 11 range, and as it hit 10.9 or 10.8 volts it shut off typically around a volume of 32. The red power wire in my boat that never seemed to have an issue with my old stereo until it fried was determined to actually be inadequate for the power flow for the new Kenwood, and probably was the culprit of my failed older unit. I offer this sound advice: Run a new pair of positive & negative wires directly from the battery (with an appropriate fuse of course (the deck has a 10 amp fuse in it's back so I would use that at the battery) to the stereo. Check the voltage as you turn the volume up into the high 20's and low 30's to ensure you are still getting voltage in the mid to high 11-12 volt range. The stereo is designed to require a minimum of 10.8 volts to operate, and when it drops below that it protects itself and shuts down.
