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

The first thing you must do is to confirm that you have voltage at the amp. Just because the fuses look good, that doesn't mean you're getting power to the amp.

With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp and the head unit on (so the amp will have remote voltage applied), touch the red lead alternately to the B+ and remote terminals of the amp. If the voltage is below ~11 volts, you need to check the wiring feeding whichever line is too low.

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.

SOURCE: To bridge a Kenwood KAC-9102D

Hello laurogleal,

The Kenwood KAC-9102D is a mono amp. There is no bridging. Having two sets of terminals is just a more convenient way of connecting two subwoofers. The amp is stable down to 2 ohms impedance, so it is safe to run 2 4 ohm loads in parallel.

Hope this helps.

SOURCE: want to bridge my subs I have a kenwood kac-719

from what i have read about your amp, it is already a mono amp, and rated for 2 ohm's, so all you have to do is wire the subs in parallel (both positives together to positive and both negatives together to negative) or series/parallel if you have dual voice coils (both positive and both negative paired on each sub, then positive from amp to positive on one sub; negative on that sub to positive on next sub; then negative on sub to negative on amp) Note though, with two dual voice coil subs, you can have a 1 ohm load with the first set up, which can damage your amp. Let me know if this helps :)

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

When i turn the music up sub cut off blue light stay on red triangle cuts off


Hi, the amp is going into protect mode. You can either keep it turned down or possibly reconfigure the speaker connections for a higher impedance. If you tell be the model of your sub, I may be able to suggest a better arrangement.

There is a manual here if you don't have one: http://manual.kenwood.com/en_contents/attachDownload/6017/

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

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.

I need help


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.

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.
