My Kenwood KAC 9152D 1800W AMP acting funny

Hello. i have had this amp connected to my 2x IN PHASE 2800W subs for about a month now, and it has been working perfectly ever since i hooked it up. I was listening it music one day and they suddently switched off and when i looked at the amp the light was blinking and clicking noises were coming from the sub. The next day, the amp would only light up for 1 second, the sub would then make a very deep noise then the light on the amp would simply switch off and there is no power going to the subs now. any help is much appreciated.... THANKS!!! marv~

Re: my Kenwood KAC 9152D 1800W AMP acting funny

My kenwood has just done the same thing it is a KAC7202 960 watt, i dont think it is the channels though im not too sure this is relevant but my power light blinks too. i just hooked up my memphis 1 fared power cap up to it i think i have a ground problem because on my model i have a smaller ground for some reason that needs to go to a seperate ground.

Sounds like you got the wrong speaker load by either parralleling some speakers or else you bridged the outputs in such a way to create the wrong speaker load or maybe all of the above. In short, it sounds like you have blown at least one of your output channels and its time for a trip to the repair shop. I suggest you disable your amp at once so that it doesn't do any more damage to itself.

I have a kenwood kac-9152d amplifer and it works just fine for about 10 minutes then just shuts off and subs dont work, about 30 seconds later my amp turns back on with the subs.

make sure it's well ventilated. If there's no air flow, then there is no way of cooling down and to protect itself it will shut off. Make sure the speakers are wired correctly as per amp specs. too many subs or subs connected improperly can draw too much current and shut the amp off, but you will notice this when you turn up the volume to a certain point and the amp shuts down.

Amp has power, turns on with stereo, but sub isnt playing... all connections are good.. whats wrong?

if you have a protection light that is on it means the amp is in protection mode and wont allow any power to the sub this usually happens when the sub or wiring shorts out or if there is an internal failure in the amp or if its overheating. check the wires and connections and test your sub on another amp.

either bad ohm load or over heat if the ohs on the speaker wires to the amp are lower than specified use in the manual it will act funny cause it is pusing harder than its meant to and if it gets too hot either bad location or bad amp you can try turning the gain down a little until the amp stays on constantly at high volume

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-

Kenwood KAC-8401 light goes from blue to red when turned on

Either the amp is ad or the sub got shorted? You can check itby disconnecting the Sub and seeing if the amp comes on blue then. If yes, then the sub is shorted. If no, then the amp is shorted. Also chck the voltage AT THE AMP. Make sure that it is above 12 Volts.

I need help

Most of the time if the red light is on the amp is no blown but some times it does this cause the subs are hooked up in the wrong way. If the amp is only 2ohm stable and you hook the subs up to it at 1 ohm than the amp will not work so I would check this frist.

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.
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.
