I have a kenwood kac-9152d running a 10 inch rockford fosgate power t1 and the amp keeps going into protect but i have a smaller kenwood kac-8102d running on another t1 and i have no issues with it why...


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.

Power amp wont power up


Check the fuses-should be a pair of 30 amps on the side. use a paper clip and jump power from the power+ to the remote+ and see if that lights it up-if it does than your remote lead isnt giving it juice-

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.

The amp says it's 1 ohm stable, so assuming the DVCs are dual 4 ohm, you should be able to connect all "+"'s together and all "-"s together, like the picture below:

As for the amp shutting off for a few seconds, it sounds like it's either:
A) Not getting enough power at high volume.
OR
B) Overheating.

The cap on the +12V to the amp should help, but putting a meter on the +12V might tell you whether it's dropping too low (<11V).

When you first turn the volume up, how long does it work fine before shutting off? Is it with the vehicle running or not?

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.

Amp stopped working...


Has the amp been overheating lately? It's quite possible that the amp could have just blown. Smell around the outside of the amp for an electrical burnt smell. If available, see if a friend also has an amp hookup and try removing your amp and copnnecting to the friend's cables. That will tell you if it's a wiring problem or an amp problem.
