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.

Usually, protection mode is caused by one of these conditions:

  • Shorted speaker outputs.
  • Speaker output shorted to ground.
  • There is an internal issue, causing DC voltage to be present on the speaker outputs.
  • Amp overheats.
  • Ground connection is insufficient for amp or HU.
I'm not sure of the history or symptoms of your amp, but those are the reasons why the amp could go into protection mode.

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 :)

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 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.

I bought a kenwood kac 7204 amp yesterday and i hooked it up to one 12 and one 10 and it sounds good but it gets really hot and it even shuts off do you know what might be my problem??


What is the impedance you are driving. If the load is too low then it will cause the amp to go into thermal shutdown. Look up the recommended impedance for this amp.

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.

LOW VOLTAGE


start with a voltage meter see if you have 12 v

check your ground
check all your connections ... "most the time i will simply rewire the whole sound system"

hope this helps

If it only does it when bridged, the ohm load may be too low.

Is it blowing the fuse on the amp or the one near the battery?

Doesn't turn on


You need to confirm that the B+ voltage isn't dropping at the amp.

With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp (not on the point where the ground wire connected to the vehicle) 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.

Measure the DC voltage across the B+ and ground terminals as well as across remote and ground. If you have less than 11 volts when the amp tries to power up, the amp could be shutting down due to low voltage. If the voltage remains near or above 12v, disconnect all speaker wires and signal cables from the amp. If it powers up, the wiring needs to be checked. If it still shuts down, the amp likely has blown output transistors.
