Re: my KAC-X812D amp is stuck in safe

From what you are explaining here, it suggests that there is an internal problem with the amp (Blown mosfets, pre-amp etc.) I suggest taking the amp to an authorised service centre.

Best subs for the kenwood x812d

Try and match the rms output of the amp to the speaker , if the amp puts out 150 watts RMS make sure your speaker is at least 150 watts RMS.

Which speakers (Front/Rear) to buy that match Kenwood KAC-M846 4/3/2 Channel Amplifier.

I don,t no where you are reading thease articles from,I installed car audio equipment for over 40 years, Untill i retired a couple of months ago, Who ever is writeing those sort of articles does not have the slightest clue what they are talking about, It is the opposite way around, It is allway better for yor (Speakers) To handle more power then what your amp puts out, Then you will not blow the spaekers, It is best to get speakers at least 20 watts more then what your amps maximuin (RMS) Watts are, Hope this helps you out, (PS) 50 watts (RMS) Is what most people go for, It is in no means (Under) Powered.

I need to know the wattege of a kenwood kac -624

The KAC-624 is a 40 watt x2 @ 4 ohm RMS amp. 55 watt x2 @ 2ohm. 110 watt x 1 Bridged I assume at 4 ohm. Manual does not specify. It can run 2 ohm in stereo mode but is unclear on mono impedance requirement. It can run 4 ohm mono at 110 watt but at 2 ohm?

Kenwood Excelon KAC-X812D mono amp

Right next to the rca inputs you will see a reset switch, Reset the amplifier by holding that switch in for about 20 to 30 seconds. This amp has a microprocessor in it that controls the fan. The LCD display that you played with only shows the status of the fan, it does not control the fan. the fan should turn on when the amp starts to get hot. It operates at high or low or stop. If the fan never comes on, even when the amp is very hot, you will need to take it in to be serviced. There is no easy fix to some of the problems. You need the fan to work, so check it out soon and determain if the fan ever comes on. It may take a while to come on, but if it comes on after it starts getting hot, it is working.

It comes on but

I believe that the amplifier is in protection mode; more than likely you either have an internal short in the amp or a bad speaker running off of the amp.

If it's only 2 months old, it should be under warranty. Have you tried to get it repaired under warranty?

Any car audio repair shop should be able to repair it.

If you want to repair it yourself, it's possible but you'd need basic test equipment and soldering/desoldering tools.

The following page shows you the basics for amp repair. Your amp is somewhat different than the one shown but the troubleshooting/repair procedure would be similar.
