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?

New 200-2 amp installed in 2008 dodge ram quadcab with 5.7 engine and 136amp alternator- when voltage goes over 15 with power demands amp shuts down for a couple of seconds at a time from what i was told...


The problem is that the numbers on that amp might not be correct. If I'm not mistaken, it's not considered CEA-2006 compliant. So the "birth sheet" might be skewed provided the picture is the correct amp you are talking about. Back in 2003 or so the Consumer Electronics Association (CEA) got with all of the audio companies and pretty much told them that they needed to regulate the ratings on amps by 2006. They made them put two ratings on on the birth sheet. They put a rating of 12 volts as a minimum and 14.4 volts as a maximum. A 15 volt load to the amp will cause it to go into protection mode. What confuses me is how are you getting 15 volts with a 136 amp alternator and other electronics running.

The problem with my marshall ma100h amp is that out of the box brand new it stopped working within a few days. Earlier I turned on the amp power switch and let it warm up. About a minute later I kicked on...


Brand new? Take it for warranty repair IMMEDIATELY... don't mess with it !!!

The only thing for you to check is that you did not turn on "STANDBY" as this shuts down the power amp and the capacitors will bleed off and sound will fade. Try switch in both states before complaining

ONLY use the amp in STANDBY for a brief period (20 seconds) to let the tubes warm up... Leaving in STANDBY for a long period straains the input filter capacitor. If you are done with using the amp, turn it off...

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
