Question about Kenwood Sirius KDC-MP522 CD Player

Volume turned up, kenwood shuts off briefly...

My kenwood will work fine until I turn the volume up. Then it shuts off completely and then turns back on again..This continues on again and off again. I have checked ground wires, loose wires, connections, disconnected amp., checked fuses, still same thing happens with or without the amp connected or with or without the speakers connected. The CD player is installed in a boat with a 400 watt amp and blaupunkt speakers. I've noticed the stereo gets hot to the touch towards the top in the back. Any suggestion?

    Would it still be an amp problem if the shut down of the stereo occurs even when the amp is not on? Please let me know..thank you

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.

I had this same problem. but it only happens if the car is off (no alt for power). I believe that the head unit simply is just not getting feed enough power so it trys to restart itself.

I have the same problem in a car.. my system is based on a 900W rms kenwood amplifier, and 1k rms Pioneer Sub. When I turn up the volume the amplifier goes into prtection mode and will start working again after a while. I'm thinking that it could be a reason of loss of power and maybe a capacitor or thicker wires should be installed.

If this is in a boat, I would check the amp unit for moisture damage, as a marine items is a specially built units that fends off water as well as moisture damage exposture. it does not mater if the amp is enclosed inside the hual or cabinet. The problem you are encountering is most likely because of a bad main amp unit, as if you disconnect the speakers and turn uo the unit, and it still goes into protection or shutdown mode, something is wrong with the amp. Like I said before, the fault is most likely due to water damage or moisture damage to the main printed circuit board. Good Luck.

I have a kenwood kac-9152d amplifer and it works just fine for about 10 minutes then just shuts off and subs dont work, about 30 seconds later my amp turns back on with the subs.


make sure it's well ventilated. If there's no air flow, then there is no way of cooling down and to protect itself it will shut off. Make sure the speakers are wired correctly as per amp specs. too many subs or subs connected improperly can draw too much current and shut the amp off, but you will notice this when you turn up the volume to a certain point and the amp shuts down.

Kenwood new sterio shuts off when turning up volume


You may have a short in a speaker. Check to see that the wire terminals on the speaker itself aren't touching any metal. Even 1 terminal touching metal will cause issues. Hope this helps.

You need to make sure you ohms are correct if there too low this will happen to protect the amp.

The amp says it's 1 ohm stable, so assuming the DVCs are dual 4 ohm, you should be able to connect all "+"'s together and all "-"s together, like the picture below:

As for the amp shutting off for a few seconds, it sounds like it's either:
A) Not getting enough power at high volume.
OR
B) Overheating.

The cap on the +12V to the amp should help, but putting a meter on the +12V might tell you whether it's dropping too low (<11V).

When you first turn the volume up, how long does it work fine before shutting off? Is it with the vehicle running or not?
