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 :)

I have a kenwood kac-728s and two coustic 10in. subwoofers hooked to it and every time i start my car and the radio powers on the two 20 watt fuses on the amp blows.any ideas?


That is pretty much saying that the amp's power supply is shorted or at least has a low resistance path to ground which is causing the fuses on the amp to blow. The amp has protection circuitry to prevent damage to the output stage so that is not what is causing this. Is the amp new?

My Kenwood KAC-929 gets power but DOES NOT put any sound out. Whats My Possible problem(s).


Hello Spicer_kyle6,

Possible problems: 1) No output from the head unit. Try a different set of preamp outs. 2) No input to the amp. Check the RCA's and make sure that they are good and coming from a functioning preamp or subwoofer output on the head unit. 3) Input gain turned off or down too low. 4) Speaker wiring shorted, grounded, or open. Check all wires. 5) Speakers defective. Connect to a known good output to test. 6) The amp itself could be defective and still show a power-on indication.

Hope this helps.

Kac-ps201t problem


I had a similar problem with a KAC-X812D Kenwood amplifier.
My problem turned out to be that the RCA inputs were so sensitive, they picked up interference from my head unit through the RCAs.
I replaced the head unit with a newer model, and had no problems after.

This may not be your case, but hope it helps.

Install my Kenwood KAC-9102D in my 2006 Acura RSX Type S


You will probably need to use a Line Output Converter (LOC). They're available at virtually any shop that sells car audio.

Many times, the outputs of the OEM amplifier will have significant DC voltage on them. This could damage the input circuits on the kenwood amplifier.

Let me know if you have any other questions.

Amp won't turn on don't know if amp is fried


Very possible that you have a blown power supply in the amp. If you are running a mono amp then there is a very good chance that you have loaded your amp with too low of a speaker impedence and fried the power supply and maybe the output section of the audio area. Hope this helps.
