Is there a margin of error allowed (say + or - 5%) that amps must fall into to be considered CEA compliant?

That as well as multiples of same amplifiers being constant. Like sending 20 of them brand new for testing. And having them all within same range not all being different.

all i will add to this is even db-r himself has said previously low voltage does not kill amps.

This, right from the mouth of an experienced amplifier repair technician.

never said you could "get" more current
I said it "takes" more current at a lower voltage for the same output, which creates more heat...

you gonna call all the electrical engineers in the world wrong? you gonna tell the engineers that designed the amplifiers wrong?

you ever see a fuse holder melt? more than just a bad ground can create the issue...

get a clue dude...

and remind me not to use the company that you are "in the field" for....

You really are an idiot.

Definitely believe that which you stated. Your favorite reason appeared to be on the net the simplest thing to be aware of. I say to you, I definitely get annoyed while people consider worries that they just don’t know about. You managed to hit the nail upon the top as well as defined out the whole thing without having side-effects , people can take a signal. Will likely be back to get more. Thanks

and if you bother to actually read we have all told you already, low voltage is NOT what causes it dude... the heat from the higher required current does..

low voltage is the cause and heat is the result

cause and effect so to speak ...

you really are dense.. you just wanna argue is all.. you have yet to post anything substantial to make your point have a shred of validity whatsoever kiddo...

others on the other hand have so just STFU and GTFO with your opinion or post actual facts...

There is no additional current draw, and no additional heat when the input voltage drops...

You are either a troll, or an idiot... or perhaps both...

@azucenaydaniel Just like any amplifier with protection against overheating, this series will shut down if the thermistors on the board sense an unsafe temperature and shut the amplifier down until the temperature is safe again. This unsafe temperature is caused by lack of ventalation through improper placement, low voltage drop, low impedance and clipping/distortion.

@MaFiAPENGUINO If you do not have the electrical upgrades required by the specific model you selected then you will certainly have failure. Electronic components are sensitive to low voltage, heat and clipping which is exactly what happens when you get an amplifier that is far too big for your alternator and battery(s). What model did you purchase?

MaxxsonicsUSAInc June 17, 2010 11:37 pm

@MasterDJRenn As voltage drops due to the lack of current and voltage in your electrical system, the amplifier draws more current, thus creating more heat in the components. What electrical upgrades have you performed and what is the exact model amplifier you have? If you have the proper electrical upgrades, running at 1 Ohm or higher and have the proper settings to minimize distortion then you will not have any issues.

this is from Kinetiks site:

My amplifier has a highly regulated power supply that makes the same power no matter what the voltage in my car is, so I don't need Kinetik Power Cells!

Wrong! Ohm's law is not negotiable. Yes a highly regulated power supply can help stabilize the output of an amplifier, but the power has to come from somewhere. If an amplifier is trying for 1000 watts output and your voltage is at 14 volts then you need 72 amps of current to provide this (14.4 volts x 69.4 amps = 1000 watts). If voltage drops to 10.5 volts while the amplifier is trying to do 1000 watts, a regulated power supply will automatically demand 95.2 amps of current. If the electrical system was already taxed at 69 extra amps, then 95 amps is only compounding the original problem, lowering the voltage even more and starting the downward spiral to fried electronics.

should I keep going?

pretty sure that several of us said the heat caused by low voltage kills it.....

ohms law is not negotiable and supports that staement 100%...

You guys that don't like MB Quart (Maxxsonics) stuff, please convince me they are "junk". This is a serious request as I am pretty open minded. Full disclosure: I don't compete in SPL competitions mainly because that isn't my thing but, do like it loud and clean. I don't sell or work for any audio company or retailer but, my history in car audio goes back to the late 80's. Please make your argument against Maxxsonics with proof, stats or tests that can be verified and checked. However, one incident of an amp failure is not enough to to constitute or prove your argument. Have at it!

I dont care for their amps but I got 4 mb component sets

you have been in this game awhile

what do you say about the low voltage creating excessive heat?

Without even reading a dmm you can tell when you got crap electrical that amp gets hot. I rebuilt one of my old alts and banged the hell out of 2 d9s and rarely got warm. I would say there is a connection there

Can you elaborate on your reasons for not using their amps? Honest question here, I really value your opinion on this topic.

Gonna chime in here. Running the DSC4125 and DSC1500.1D right now. Single subwoofer set-up (TC 3hp), fully active 2-way front. No problems what-so-ever, lots of power, great output, and very clean sound. There's not much else I would go out of my way to buy at this time unless it has a better price/performance ratio and even more power.

Head to head with an SAZ-1500D in a subjective test (direct swap), I could tell no audible differences, so I decided to sell the SAZ and pocket the extra cash. No, I did not meter it, no point for me. Yes, I know the SAZ isn't a pure SQ amp either, but it's an amp most people are familiar with and served as a great comparison. It was also the revision right before they retooled the amps to the new, SAZ v.2's, so it was pretty much new at the time. I guess my main point is that these two particular amps are/were fantastic Maxxsonics products. Does this speak for the entire company? No clue, I've only played with a few of the other Discus series amps (which also delivered). However, I definitely wouldn't scoff at their MB Quart products.
