What would be the main areas that you think need to be improved before the amp is ready?

ok im on my lunch break so i cant get to involved here. but it seems many of you have not read the entire thread? if you cant tell this was testing in 2 different vehicles one on 12 volt and the other 16 volts. there seems to be alot of controversy but im unsure why? the results seem very straight forward and are exactly the same results a dbdon recorded in his tests. the 16 volt test was 0.5 ohm load with a spl sub, and the 12 volt test was 2ohm load with daily driving subs. i dont see the problem with the tests? in the 12 volt people seem to think the subs were the problem, yet they never blow up they take the power like champs. we tested the sd8000 in 12 volts with less power = to that of the stetsom amp in the car and it still was 0.7 dbs down. so you cant say a test with the same subs with the same power but different amp is a bunk test.
as for who tested these amplifiers that was both myself and mike and mark as you can clearly see in the movies. thats it for now if anyone has more issues feel free to brong them to my attention and we will try to clear things up ok.
we are not bashing any amps in here just stating results take them how you want. and please test this amp yourself when you get the chance.

Jordy I got your msg and yes the amp needs a tweak from the version Murillio sent and he has stated that it was an older design which is ok. I also said the amp has potential, it is 30% smaller than the old 7KD and was able to keep up with it at 18 volt despite the problems.
Now I know it don't hold up with a 7K2D but I have not tested the most current version of the SD8000 YET. We will have to give Murillio some time to receive the amp back and make the changes to further models.
SD has a good thing going I think and I have nothing against new companies willing to work with the consumer as closely as they did to get some tests done.

Some tips for who will test:
Look at the ON state blue LED:
If is strong the amp is OK for burp, if its not the amp intered in Economy mode, made for daily use and it gives 3dB less until you rise the volume.
As TL systems takes 2-3 seconds to measure (funny because the pressure sensor only needs few milliseconds) you may start in Economy mode and finish in normal mode, and I think this could affect the SPL result.
So please look the led before burping people. The Economy mode enters in a few seconds after que amplifiers is ON.

Is there a way to defeat this 'economy' mode so that it provides full power for the entire burp (say, without rolling the volume)? Or is it only in economy mode for a few seconds after turning the amp on? Just curious.

Hello.
No, this is programmed in the microprocessor.
You have a time before the EM starts.
The uP detects that you are not using the amplifier at full power and reduce power consumption and output, until you rise the volume again.

As far as the rex goes we built the boxes a week before, 1cft each and called it a day. The subs are treo`s that were won at a show and didnt feel like buying new subs for a test.
Head to head, same imp, and boxes, and voltage, is what we were after. Mabye Don can send the amp to you youile. You can test for your self.
On 16 volts this amps puts out huge power, but not all the power is usable due to distortion. But amp for amp same scores on 16 volts as a stetsom 16 volt dual bord.
