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.

either the wiring your running is short circuting,or the amp is shot, or the subwoofer is shot, try hooking the same speaker up to the other amp. along with the other speaker to the other amp, see if the same thing happens.

In protection mode do you mean the light comes on and it plays music and stuff? If that's the case, that's what the amp is supposed to do. Protect itself from a power surge

Just woundering if i could bridge one sub to front and one to rear the subs are kenwood w3514 dvc subs the amp is kenwood kac-x501f


Hello bigmac208,

Yes, that would be the best connection for both the subs and the amp.

I'd wire the sub voice coils in series since the amp will not be stable at 2 ohms when the channels are bridged. The power will be somewhere between 100-200 watts RMS to each sub. While it's not pavement pounding, it should provide pretty good bass, especially if you tweak the crossover and boost settings for best bass response.

Hope this helps.

Blown amp, on circuit board, connecting fuse and power connect.


These amplifiers dont employ reverse polarity protection that most higher priced ones do.
The amplifier(s) are definately in need of repair - probably power supply - IF boss sells parts.
Chances are, however, the repair will meet or exceed the cost of a new (appropriately rated) entry level amplifier.
Just about anything can be repaired.... question is, are you willing to pay?

Amp trouble


You proberbly just blew that channel on your amp, maybe you should just take it in o a sound shop and ask them to fix it, the problem shouldn't be big enough for you to throw away the amp...
