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: why does the kenwood kac-9103d has two sets of

Hello damasogrizzl,

The 2 sets of terminals are connected internally. Having 2 sets just makes it more convenient when wiring multiple subs. The amp is rated for 900 watts RMS into a 2 ohm load. The specs claim that it is stable at 1 ohm but does not give a power rating.

The Radial SD competition series from Phoenix Gold are rated to handle up to 600 watts RMS. If you have the model RSdC124 with dual 4 ohm voice coils, it would be best to wire the voice coils in parallel for a 2 ohm load and connect the sub to one set of terminals on the amp. If your sub is the model RSdC122 with dual 2 ohm voice coils, you should wire the voice coils is series for a 4 ohm load and connect the sug to one set of terminals on the amp. Wiring the voice coils in parallel will result in a 1 ohm load. And, while the amp may be stable at 1 ohm, the sub will be seriously overpowered.

Hope this helps.

Sounds like the bumby road may have made ur output wires touch and short out some output transistors in ur amp. Or ur amp has bad solder connections. Either way have ur local repair technician have a look at it

My kenwood kac 9103d just crapped out on me and i am looking to buy a new amp but when i bought my sub the guy specifically wanted to know what type of amp i had to match it to the sub. so now do i have to...

More specifically, the amp must support the resistance of the sub, or subs. If your amp is 2-ohm stable, it can run a sub, or subs wired for a 2-ohm load. Also, whatever the recommended maximum wattage is for the subwoofer, try not to exceed this much, if at all, with the amplifiers wattage.

Adjusting wattage on kenwood kac 9103 class D mono amp

That amplifier is 900W x 1 @ 2ohms.
If your subs are 4ohm SVC wired Parallel, resulting in a 2 ohm load, each sub will only see 1/2 of the rated power. (450W ea.)
Your gain (sensitivity) setting should be between 75% and 85% to max. You will be fine.

Repairing a kenwood 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.
