Mb Quart Discus 2000.1D running hot?

That amp is getting hot in one of two ways. If you are smelling "that electronics smell" it's probably the epoxy or glue on the torrids burning or melting. You probably have low voltage or you are clipping the amp and you have no idea.

 
wut a lying peice of poop...no friggin way it ran at .5 moron,go back to smd with that crap

HA! you fail.......

I ran it @ .5 against a pair of DC level 4's for more than a couple of month until I was broken into. and btw bud, there was about 10 others on THIS forum running them at .5 with NO problems...

 
i have ran 1 of my 1000 at .5 all day and did it to a hifi brtus 1206d and both got really warm but not hot maybe like 100 at case
your not the first....

and im sure if he did a search he would find more than 5 threads about guys running them at .5

 
can someone who knows what they're talking about explain why voltage dropping would cause the amp to get hot?
You are simply taking DC and converting it to AC. If there's not enough DC available (Battery voltage) and you are demanding maximum watts (Input signal maxed out = most AC voltage) then you are over driving parts which causes excess heat and part failure.

 
Im running the same amp at 1 ohm on a level 4 xl. I set it with the dmm but have never found it to be hot. Has gotten warm after long sessions but not so hot that i couldnt touch it. Also have a 4125 and have never had any problems with either of them.

u have the amp set for how many watts? u have 1/0 along with a nice battery that will help with bad voltage issues.

 
So the MB Quart Discus is a decent amp? And it capable of .5 ohm daily? I might have to get one and try it out. Is it better or worse then Hifonics Brutus or Audiopipe.
I dont know about this "bad batch" but back when they first came out I bought one, and It was a great little budget amp. I can be ran at .5 as long as you have the proper electrical, and dont abuse. Ive also owned a audiopipe ap30001d amp and was really happy with it.

 
"running hot" or "too hot" is a topic that comes up on the forum a lot and most often, there is never any actual temperature reading to support the "too hot" concern.

It's always difficult to determine what "running hot" really is and most often people put there hand on the amp and say it's "too hot to keep their hand on the amp for more then a few seconds".

Putting your hand on the amp is no way to determine how hot the amp is getting and in no way can determine how hot it is or wether or not it is too hot.

Example: Put your hand on your dashboard around noon after it has been exposed to the sun for a couple hours and you won't last more then a couple seconds and yet all of the electronics in your dash board works just fine.

How hot does your dash board get?..... maybe 120-130 degrees?

Some say 100 degrees is too hot but the water in a hot tub is 100-105 degrees and certainly no concern to you and definately not electronic components.

Almost all amplifiers have thermal protection and certainly all of our amplifiers have this feature built in.

Our amps have a thermistor on the heat sink as close as possible to the output devices which are creating the heat.

The amps are designed to shut off if the heat sink should reach 165 degrees which is as hot as you would want the amp to get before component failure.

Now, having said this, it doesn't mean that your amp is not running hotter then it should and there are many things that can cause an amp to run hotter then normal....many have mentioned some of the cases.

rather then trying to guess or go back and forth here with 20 Q & A, I suggest calling our tech support line 877-629-9227 and talking to the tech.

He would be able to properly trouble shoot the problem (if there is one) and help you resolve it.
