Wasn't it already explained that it wasn't an issue with the amp but rather the HU or something?
How could the Hu do this. Out of the yrs that i have competed i have never herd of a Hu doing somthing like this and if im wrong wow that sucks.

I ask them to send the amp connected to that coil to you, and you could send me a MP about this. What test you did on the amp that tells it is sending a DC current?
Maybe is a new thing for me, but DC current usually won´t do that on a coil.

the amp is here with me and it is putting out dc current. i don't think it was always doing this. but once you started replacing parts in it, something got out of whack. so the headunit is at fault, but always burnt one coil of one sub on the same amp? come on you guys are smarter than that. the other 7 amps and 7 coils were always fine. so some how the headunit selectively chose this amp and the same coil of every speaker hooked to it to destroy in one burp. that's amazing.

Please show here your measurements on the amp that indicates that it is sending DC. This amp had some FETs damaged due to the coil problem, and it was playing under 1 ohm at 16V...
You want more info about the problem? Track change and thumpf on subs, remote on and thumpf on the subs, and a few more.
You could even send me some mail, or talk on MSN before doing all this here, I would give you more info, but you never did that.

I have seen this one time before in a ss1-2 set up im going to have to ask him on why this happens but i will say its not the Hu.

always the same coil of the same sub, on the same amp? man it's one amp messed up why can't you just own up to it and move on. it's really not a big deal except you kept telling craig it wasn't the amp until 5 or 6 z subs were toasted by it. and i believe you guys spent 27 or 28hrs driving back and forth to my place to get subs.
The amp was tested there, and was put in parallel with other amp (+ to + and - to -). If the signal was a little bit different it would damage the amp. Also any DC would make the other amp act like a short and protect the amp.
We also burped this amp on a kicker solox 10" several times.
On top of that, I asked Rusty to take the amp to you, because if there is a problem that I didnt find you can do it. So if you still think is the amp please do your measurements, the amp was taken from the install and sent to you.

Ryan....sounds like you have some bad rectifiers,in that amp,and or the output fet's drivers are bad.I have repaired Chucks sd8000.1,but it seems like the amp,is drawing so much current,that the copper tracings,on the negative side of the input fets,cant handle it,and it burns the copper tracings into.

Murilo, why dont you give your customer the benefit of the doubt? You are always quick to defend your amps and brag about how bullet proof they are, while in reality they aren't. The Customer should always come first in my opinion.

Ryan,
Did you try that woofer on another of the SD amps? Are all the 12 neos on the Z charged the same? How about that amp reaching "clip" sooner than the others and therefore cause the DC when overloaded on the input?

Yes, you are right.
There is no bullet proof equipment.
I was only saying that because on this case I was there to see what happened. Everything will be fine.

We did exactly that to a 9918 powered by four Z2HV.
The master amp was dropping out on one coil, but still passing signal to slave amp...
uuuuuuuuu i never see a coil burn like that!
that is serios DC current.
i think the SD amps are good , but Murilo don't relly knows what he have. the SD is try to take stetsom over, doing 5 years warranty, we can see clear that lots people have troble with SD ,in lass than 1 year. I like to see how that will go on the next 4 years, is no company that can alive ,be in this marketing just to fix burn amps.
Stetsom do 1 year warranty but we take care or clients. its easy came here and said i do 5 years warranty,i like to see in true life if will be 5 years warrant from SD. Murilo let me tell you santing... Ryan is the most professional instaler i ever see,he show me lots the tricks i use now to get my car louder and louder... he have ben involve in lots loud projets arould the world, and he is world champion for db drag, i guess he knows what he is talking about, he also do repairs for DD amps and subs,he have all the respect from me,and all the guys from the carolinas(North and south) knows him, i just wish i cud be in the USA now , to help ryan and Craig. But best luck for SD,i have question for Murilo why Craig Butler is back to stetsom amps?????????
thanks
Alan Dante
