    exact same problem. it makes me sad. it lights up just normal. looks like its gonna work. then turns off. and i didnt use it for more then 2 months when i swapped cars and instantly doesnt work.

    and trust me, i take very good care of my equippment, it was never scratched or dropped or mishandled. just stopped working. anyone figure out what it is?

    power lights is green then turns off. remote is connected not sure why.

Which lights are lit on top of the amp when you power it up?

Which ones light up during the 15 seconds that it's on?

Are you running a signal sensing system or are you turning the amp on via the remote lead?

Is the signal sensing switch set to on or off?

Yes, you can do this easily.
Perform the following steps

(2)Switch it on.
(3)observe time taken for switching off.
(4)immediate to shut down over current protect(5)3 seconds to shut down DC protect.
If over-current protect do the
following steps
(O)unplug the amp.
(1)download NR806 service manual.
(2)open the amp metal cover.
(3)measure 7 large white resistors resistance loacated next to power transistors mounted on a large heat sink with black probe touching the middle pin and red probe to first/left or third/right pin.
(4)If this 3 Pins large white colour 0.22ohm x 2 resistor is open with infinity ohms ,
(5)replace it and jot down this channel for example left surround faulty. Usually only 1 channel went faulty.
(6)the two large power transistors next to this white resistor 0.22 ohms x2 should also be replaced.
(7)plug the amp

VCR plays 15 seconds, TV shuts off. Same without tape inserted


Sounds like a typical Switched Mode Power Supply fault, or an internal thermal fault that is shutting down the power supply, over & over. Really you need to get it serviced. You need to get a firm "Quote" for repair, remember these days repair can often exceed replacement cost.

KAC9103d been running great for a year, factory refurb. for a month been losing sub output. checked all connections again, everything good. Turned on went driving 15 minutes later lost bass ckd again red...


Could be that you have a partially roasted(blown) coil on one of your subs which will function- but will keep tripping your amp.You can check that out just by using a different set of subs to listen to and by the process of elimination if the problem goes away then you know where the problem is at.Also check your gains you might be riding the gain a little high which causes distortion which causes heat(FAST) which will cause the amp to shut down completely or some amps will decrease output in a programmed attempt to save itself.turn the bass boost down to half if you even use it at all- that too can cause massive distortion in the amp itself,meaning only that if you have the bass boost on your deck turned up and then you turn the boost up on your amp the sound signal is then WAYYY distorted which will cause a thermal shutdown too. Last thing is to make sure that your subs arent running below 2 ohms because i believe that particular amp is designed to put out about 900 watts at 2 ohms.good luck

Power to Amp but no lights and does not switch on


(1)When the unit is switched on the relay clicks in,but no sign of life, and then five seconds later the second relay clicks on/off don't know which. This symptom is DC outputted to speaker terminals. Check any DC at power amp stage output.(2)Must have blown up.
Positive. If Caps blew, your amp shutted itself down within 5 seconds due to + & - power supply creating an unbalanced +B & - B voltage not allowing your amp to turn on.
