kicker has won a few SQ comps buddy... have you actually heard an L7? I bet if you heard an L7 and your favorite woofer the dub7, you couldn't tell the difference without looking at them.
this guy needs to be banned b/c he thinks he already knows everthing so whats the point of being on here except just to misguide people with his inaccurate attempts to explain things.

exactly
you cant go lower then ur DCR resistance with ur givin wiring options.....imp rise goes up, not down buddy.
jl is good stuff, however for the money u pay you might as well surgicaly remove a testicle and and use that as payment too. JL sounds nice but isnt geared towards spl at all.
some of the things youve been quoted saying make absolutly no sense whatsoever, and are entirely noobish in many ways. but hey we were all noobs aqt some point in time, some just say more stupid shit than others....
your comment about wishing they made circular cones again made me lol so hard i almost shit myself....
This guy is the perfect example of the old saying, "if you can't impress em with brains, baffle em with bullshit.

i allready know these things that no-one knows how to say without insult, and some of you don't even answer, you only insult... your just makeing yourselves look more pathetic, infact not only do i know what the problem is (which this thread did not help me with....) but i fixed it... this is another example of people not careing about audio and just talking trash, seriously get a life i post to have questions answered... not hear people that don't know me and spend their lives slaving to the internet all day tell ME that I **** at life...

You ask questions and then get all pissy when you get the correct answer but it isn't what you wanted to hear. You act like you know everything but every time you post you prove otherwise. Your behavior is accurately described as childish. If you actually want to learn then fine there are those of us on here who would be more than happy to share som knowledge if you would only get the chip off your shoulder, your head out of your *** and accept the fact that you don't know nearly as much as you think you do. The reason you get a bunch of crap from a lot of people on here is you persist with posting your ignorance and keep trying to pass it off a knowledge even when repeatedly being presented actual facts that directly contradict your BS. If you want to grow up a bit and actaully listen to what the knowledgable and experienced people on this forum have to say, by all means, stick around. If you want to continue with your antics, please do us all a favor and do it somewhere else.

ok i know i got alot to learn about audio but, these statements are rediculous
you in this case where the one spreading the false info... this is actually real dangerous, if i had used ur advise as you said it my load would be below 1 ohm... i would've probably blown my subs and fried my amp if not for protection circuitry
not lower than DCR? not the issue, in fact in a subwoofer inductance is generally responsible for about 20-40% of total nominal impedance... that leaves DCR (voice coil resistance including lead wires and terminals) to 60 to 80% how does that effect the sub? if i went by the DCR, my systems nominal impedance would be .4 considering the dcr for 1 10w6v2 in series is 6.3, and in parallel 1.575... since i don't know the speakers inductance and IEC's standards state that the true nominal impedance may drop to 80% of what rated nominal impedance, i think it was pretty safe to say (without knowing wat inductance is) that impedance for that 4 speaker load could've very well been dropping below the "rated" 2 ohm load.
excuse me, what?!?! i've bought 5 of their w6's and one of their most expensive amps. I've heard (or seen due to volume) setups of dd's that have won SQ comps and kickers that have won SPL levels like 170db's and i am thrilled with my JL, and the price i paid for them, further more i have both of my testicals and they are functioning perfectly...
ok whoever thought up the trend of the word noob should be shot... esspecially because it is used so often to describe people that you do not know and could very well have more knowledge about you if not in some areas but not all... i am positive everyone on here knows more about something or many things than me, but i am also positive that i know more about certain issues than others
u might wanna see a doc. but the current circle cone subs they make are almost the square version with a circle cone, i might be mistaken but i believe it is the exact same motor, even if it isn't it's close... furthermore their "flagship" the solox is square and there is no round version of it, but the solox itself was round in the past i think they spelled it different, like solex... reguardless kicker has changed its focus to the square subs and mainly keeps the circles for people who won't change their setups to accomodate a square, it even says that on their website....

Ok, stop. You're way off here. You may have read a quick article somewhere about the difference between DCR and nominal impedance but your understanding of this is just not correct. I'm not going to bash you here and I really do want you to learn this so that you will not confuse people who, like yourself, don't truly understand the idea of resistance and impedance.
The first thing we need to get straight is parallel and series connections. In very basic terms, when you connect resistive elements in series, the total resistance ALWAYS increases. When you connect resistive elements in parallel the total resistance ALWAYS decreases. Your w6s have a DCR value of 3.15 ohms. Elements in series are additive. This means the series wiring will lead to a DC resistance of 6.3 ohms (3.15 + 3.15). When you wire them in parallel, you get 1.575 ohms ([1/3.15 + 1/3.15]^-1). With 4 DVC subs, you have the wiring options of either 1.575, .394, or 6.3 (note all of these are DCR values and not nominal impedance).
You say that you don't know what inductance is and I'll give a small explanation of it. Inductance is a measurement of how strong a magnetic field is, per unit area, (also known as magnetic flux) with the current you're passing through the unit. In a DC environment, your current is constant (hence the Direct Current) and thus the part of the voice coil that is acting like an inductor is now acting like a short (think of the resistance and inductance of the sub as if they're in series with each other). If the inductance is a short, you can say that its value of resistance is 0. If you now take the resistance of the coil, the sum of the inductance and resistance is going to be equal it its DCR value. Now, when we use an AC (Alternating Current) source, we create a magnetic field and get flux. With this flux, we're going to have inductance added to the DCR. Since this voice coil is one unit, the values are as if they are in series. Like I said earlier, series components do NOT ever lower in value. So we now have the inductance (which will vary over frequency) added with the DC resistance of the coil. This value, over the usable range of the sub while free-air will be roughly 2 ohms per voice coil. The resistance of the wire running to the sub is in SERIES with the voice coil so all that resistance (a very small amount) will also be ADDED to the impedance. Oh, impedance is the measurement of resistance with a real (DC resistance) and imaginary (resistance caused by capacitance or inductance) component. Also, by imaginary, this does not mean it doesn't exist but rather that its values are described with the mathematical value of "i" or the √(-1). It's common to see the impedance of an object described as 2+0.5i (where 2 is the real or DCR component and 0.5 is the imaginary component). You could also see this value in terms of 2.06 with phase angle of 14*.
So after reading all that, hopefully you will see that your subs should not drop below the value of it's DC resistance (your subs are rated at 3.15 ohms per voice coil). You should have wired your subs to the 1.5ohm DCR load, which could be done by wiring each sub with its coils in series and then each sub in parallel with each other. If you did this correctly, your amp will only see a load higher than 1.575ohms, which your amp should be stable at 1.5 ohms.
I hope this clears some stuff up.

you just told me what i said was wrong, and then said exacly what i said.... i didn't mean that i don't know what inductance means... i said i don't know what the inductance of the subs is... besides that you cannot drop to your DC resistance unless your inductance is ZERO and then your speaker wouldn't be doin much, so the fact that that dc resistance is what your impedance can drop to is flat wrong... i KNOW this much to be true or at least erroneous... because the sum of the inductance and the resistance is not equal to the DCR value as you said it is... in fact the DCR is the resistance... so DCR+inductance= nominal impedance which IS the "supposed" lowest impedance of the sub... also that "imaginary number in the inductance is simply a algebraic formula used to avoid the value becomeing 0 because it is impossible for the inductance to become ZERO... so yes techically nominal impedance is definded as....
DCR+ (x)i= nominal impedance...
furthermore another important thing to take into mind is that ratings on sub's DCR are permited to be -20% by industry standards so if the case was that even one of my subs was droping to that percentage, or if all 4 were droping to even 5% that could have been the source of shut down
ANOTHER important fact is that a 1000/1 is designed to be nominal at 1.5 to 4 OHMs it accomplishes this by adjusting the circuitry automatically "every time the amp is turned on". this means if my amp read a 2 ohm lead when first turned on a .5 ohm drop would make it cut off because the amp is adjusted to play nominal 2 ohms.. so i'm sorry to argue if thats what you take this as but i know for a fact that DCR is ONLY the resistance of the voice coil and leads and stuff, nothing to do with inductance but add the 2 together to get nominal impedance.
a general easier rule of thumb is take your DCR and muliply it by 1.3 to get NOM. Impedance

i don't know what you are talking about i said even if i don't know anything else, I DO know this... and that is true its not allways accurate but generally it's close to mulitiply DCR by 1.3 because inductance is usually from 20 to 40 percent of the DCR so yeah... what is your problem with this statement?
