Your amp is likely over heating.Does it have enough air space around it? You may be over driving it does your head unit have variable out put? if so try lowering the output volume to the amp
Hope this helps...........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.

On my kenwood KAC-8105D mono 1000watt amp, the blue light is out and my subs are not getting any power? What does this mean? what does the blue light mean??


Well normally a light near the controls and or where you put the wires for subs is the continuous power. There is a wire from the back of your stereo that need to be ran to the amp. It tells the amp when to turn on and off so it doesnt drain your battery.

When I turn up the volume the amp shuts off and displays an E-03


do you have your subs wired down to 1 ohm? The reviews on this amp is not very good, a lot of people said they had a lot of problems with this amp, a lot of blown fuses and cant take a 1 ohm load

When I raise the volume the music turns off. What would be the cause of this?


2 things could shut your amp...to low of a ohm load, or very low voltage drops. I need some more info to help you out.
1. Is the amp really hot when it shuts off?
2. Is it a mono sub amp or 2 channel stereo amp?
3.What ohm's are your subs & are they SVC or DVC?
4. How do you have them wired to the amp?
You can email me at thefowlerfam09@yahoo.com I have a idea whats going on just need some more info.

HAVE A KENWOOD AMP MODEL KAC-9102D . iT KEEPS SHUTTING OFF WHEN i TURN THE RADIO LOUD. ANY SUGGESTIONS


either bad ohm load or over heat if the ohs on the speaker wires to the amp are lower than specified use in the manual it will act funny cause it is pusing harder than its meant to and if it gets too hot either bad location or bad amp you can try turning the gain down a little until the amp stays on constantly at high volume

I recently baught the rockford fosgate P2's and i got the KAC9103 ampliyfer. and i had best buy install em both and they ran the wires too. the problem is when i crank the volume on the deck to...


It's possible that the installer cheated on wiring gauge, using wire too light for the 12v side causing the voltage to be dropped to a level the Fosgate won't tolerate and causing it to shut down.
If you have a multimeter, monitor the supply voltage at the amplifier while a friend turns the volume up. If you see a significant decrease in the 12 volts, the wire feeding the amp is too light.

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?
