more volts doesnt help things, you can fry the input side of the amp or cause it to oscillate.

quite possibly dead unfortunately then what has more volts than the hu?

If your subs quit when you were messing with your headunit then that is part of the problem. On the headunit the output voltage signal to the amps (through the RCA's) is usually controlled by the subwoofer level. The level can be adjusted from +6 to -24. You will likely want to have this set between 0 and +3, just off the top of my head. I'd be careful if it suddenly starts working though because of how "professional" the install seems to be.. You probably either have that set incorrectly or have enabled a low pass filter or low frequency cutoff on the subwoofer output, unless the subs really are dead..

Finally, someone other than adire aiming for 40+..

Larger spiders and a surround delete (yes, I said delete) ; ) Shoot for 40mm lol

was wondering when i'd see the physical outcome of this What are the excursion capabilities going to be and what are prices looking to be?

You are being taken. Get your money back and forward all viable information to Jacob ("sundownz" on the forum here), thats plain dirty.

I notice they're blaming the protect circuit on the amp. Does that mean the protect circuit was built poorly?

In that case, yes, you can make anything work. Some things just dont work as well as others for certain applications (or enclosure styles).

they are not being used as mid range.. they are being used as sub woofers.

What do you think would be more fun, 2x EMF 15's or 4x Zv4 10/12's?

Use an o-scope Check your jumper leads, its not uncommon that they can have poor connections internally (not where the alligator end grabs but where the alligator end is crimped inside the plastic sheathing).

I want a hero3 black.. just have my crappy hero2 to suffer with until later I guess..

it wont. Not any more then scoping your amp would. Honestly, to NOT believe in the DD-1 is to not believe in an O-scope. Our product does what a scope is supposed to do, but does it faster and more accurately. Regardless, I wouldn't mess with any shop or installer that doesn't use an O-scope in the very minimum. Also it does it simply and cheaper than the average scope, cant beat that btw Steve sorry if it seemed my last post was knocking on you, not my intention.

the guy's an ass, but I support his comment about setting amps loaded and the tone to use.. Steve doesnt like setting amps loaded. Sure it works.. like setting a gain with a DMM, but honesty its not accurate.

Too bad you had to move to the smaller spider.. all that wasted excursion capability...

I want 4 of these so bad.....

I found another copy I think. http://www.youtube.com/watch?v=CkOaSEy4l6k

Video taken down, anyone got a link to another copy of it?

To a point. Some can take it, some cant.

Here is some good info. As for processors, extra voltage is OK since you have far more diverse and powerful cooling options than you do with an amp. Depends on the process used for the processor. Some are high leakage, some are low, and cooling doesnt change electromigration until you get near to the point of superconductivity of the silicon used to make the CPU.. if you can get there without hitting a "cold bug" point first.

Max out your dimensions (~3ft each), tune to 30-33.

You mean a large turbo with a small motor, but no that analogy doesnt work if you understand it really. The components are meant to work at a certain voltage (12-18 as mentioned before) and if used at that voltage they will consume a known amount of current (amperage) to produce a known amount of output power. With current regulated amplifier technology this is controlled by cycling the mosfets on and off to create a steady amount of power for the second half of the amplfier. Less voltage means the controller of the mosfets cycles the "on" time longer which means the mosfets build up more heat. Heat creates resistance which means the fet controller must cycle the fets longer again which can create further voltage drop.. which means longer duty cycles... This is known as a "thermal cascade" and as you can see it is not the voltage that is the actual death culprit but just a factor that drives the issue. High voltage can kill an amplifier by creating what is known as electron migration. Basically arc (stick) welding inside the electrical components. Computer processors are an example of something that is very suceptible to this - hence why overclocking with increased voltage has the possibility to degrade or destroy processors. Pentium 4's were great examples of this

"just picking" is my guess edit - and given his responses my hedge on the hard clip seems pretty close.
