Why RMS?

Yes ah am as noob as they come. But ah what to know everything ah can about whatever im investin in. Especially when it comes to proper maintainance.

You're doing fine.... Actually in few months you'll be laughing at Xplod with us //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

 
RMS = Root Mean Square (IIRC), which is basically the mean of the power that your sub is seeing. It's a nice way to round to see how much power a woofer is seeing. Max power is it's thermal and mechanical limits, and should never be seen... it's also a marketing hype... a lot of manufacturers that don't really sell to the mass public won't even give a max power rating, just an RMS power rating
That's the best explanation I have seen. makes total sense to me now.

If you haven't boughten any of the equipment, don't buy the W7's. They're good subs, but for the money you can get 2 subs of the same quality / caliber.

Post up your budget and we can help you chisel out a good build.

Oh wow. My budget is very limited. I am selling sculptures and getting some help from my parents. I am just looking for what I like (within reason) and seeing what I can scrounge together. I only have a head unit now. I MAY only need 1 sub because I am trying to put it stealthy in a 300ZX (subcompact hatch with a hemi-topped racing engine). Pleus if I get an extra sub, i need an extra amp to feed it.

 
there's some serious mis-info going on in here that I'm sure the "technicians" that frequent this place would have a heyday with, but I'll point out a couple things.

First thing - a clipped wave doesn't contain DC, it's high frequency AC.

Max power isn't the thermal or mechanical limit of a speaker. It's nothing. Really. Nothing. That's why everyone says it's meaningless -- it is.

The reason it's meaningless is because there is no set defenition for the term - every company defines it differently. Some take the time to define it in their own terms, but comparison wise it is of no value because chances are the next company defines it differently if they define it at all.

RMS power IS a thermal power rating, and you don't, by any means, NEED to drive a speaker with an amp equal to its rms rating for optimal performance.

The fact of the matter is if you drive a 1000w sub with a 500w amp it's going to be REAL hard to cause damage because even fully clipped it's not likely a 500w amp can produce enough power to threaten either the mechanical or thermal limits of the sub. And if it approached that degree of clipping even the most newb ears could recognize it sounds like shit.

If you were to do the same thing with a 1000w amp the likelyhood of damage would increase drastically because an amp that size would produce well over 1000w when clipping at high volume.

And while it's become accepted that running a sub with an amp HIGHER than the sub's rms rating somehow reduces the chance of damage, the theory is bogus.
