Had similar issues with mine, ended up being that the ground I chose was not a strong enough ground to support the electronic load. maybe try grounding the system to a different location? just a shot in the dark

The Kenwood KAC would be 2 ohm stable.
I ran my sub's in parallel and the amp did not shut off and hit pretty well for long periods of time.
If you are running two dual voice coils.
Bridge amp, run pos and neg to pos and neg outside of box.
neg and pos to one side of sub
The other side of the sub run to the next sub
the other side of the sub to the inside of the box pos and neg.
pos and neg outside of box to the other outside terminals to create a complete loop.
If this isn't a good description post back and I'll email you a picture of it.

Circuit City ? I'll keep that opinion to myself.
If all is properly hooked up, Check the ground wire for the amp.
Give it a tug where it is connected to the car chassis, NOT the amp,
if it moves or comes loose thats easy to fix, scrape the paint off the grounding point use a high quality ring terminal and a oversize screw with a star locknut. Also check the wiring in the box.
Subs and boxes are quite heavy. And if it's banging around, I hope you have it in a trunk, they are very lethal projectiles in a hatchback should you have a accident.
My second thought is that you may have dislocated a component , solder joint, or cracked the PC board,
When in doubt see a installer. Good luck Sumthin

Nope it's not a high-to-low level converter problem, it's most likely a problem with one of two things. 1) either you've blown the output stage in the amplifier, or 2) you've hooked up your subs wrong and your amp is seeing to low of an impedance. The amp is supposed to be 1ohm stable, but we had the same problem. When the indicator light goes red it means that the amp has gone into protection mode, now you have to figure out why. If something in the amp goes bad or just disconnects from the board it will cause power protection mode. If you fry something on the board because you are running the amp to hard or at the wrong impedance it will go into thermal protection mode, however there's no simple way to figure out which has happened.

Have you tried hooking up some different subs to see if the problem remains? try this. If the problem no longer happens then you know it's your subs, if it does still happen then you'll know it's an internal problem.

Years ago I had a Kenwood KAC-821; long story short, I melted the main power wire right off of the board, everytime I turned the system up the amp would shut down.

Take you amp to an authorized dealer and have them bench test it for you.

Let me know what you find out.

Most of the time if the red light is on the amp is no blown but some times it does this cause the subs are hooked up in the wrong way. If the amp is only 2ohm stable and you hook the subs up to it at 1 ohm than the amp will not work so I would check this frist.

it sounds to me like its burnt.but with some amps the screws that hold it in place have to be screwed into the car chassisfor grounding. be careful not to srewe into hidden wires.

My Kenwood KAC 5001PS red light comes on and stays on but it still plays how's that possible


most if not all systems require a power source directly linked to the batterys main supply. depending on how your system is installed, you may also have it connected to a Switched Power Source, such as your car radio, that will only turn on when the ignition is switched to on. if im understanding your dilemma correctly, and the light stays on and such - possibly wire the system differently with a switched power source that will disconnect whenever you choose

On a kac-x650d does the power light stay on or flash


Hello mpredday,

The Kenwood Excelon KAC-X650D power light is ON during normal operation. It blinks blue to indicate BMS selection, yellow for low voltage, purple for DC voltage on the outputs, red for overheating, and green for a shorted or grounded speaker wire.

Hope this helps.

Red Light


that means you probably have a shorted speaker wire, a bad speaker or the amp itself is bad, try disconnecting the speakers one at a time and see if it turns on or not. if the red light stays on with no speakers hooked up it means the amp is bad

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

Kenwood amp kac-x401m


How long will the bass play before the amp kicks into protection mode and how loud are you listening to it? I've noticed with my amps that if they don't have enough air flow they will get hot and kick into protection mode. They will also kick into protection mode if you are running it at more than it can handle. Check your adjustments on both your amp and the head unit. Make sure you are not running more bass than the amp can handle.

Light stays red


I do belive this amplifer has a red light when it is on... I know my Kenwood does. I suggest checking all your wireing between your amp and your speakers, check the impediance between your positive and negative terminals on your leads to the subs.
