Thank-You All for your Ideas and Such; with everything that you guys have said, only 1 thing is confusing me.
I was under the impression that it is always better to have more amp power than woofer power.
Meaning that if I have a 600 Watt Amp -- I should run either one 500 watt woofer or 2 250-300 watt woofers.
Yet when reading your responses I am reading things such as 2 Type R's or 1 Type X -- etc.
The new Type R's are 500 watts RMS a Piece and the Type X is 1000 watts RMS
If someone could please explain that to me it would be of great help as I am looking at buying the woofer(s) shortly and really don't want to mess up here.
Also, I am trying to figure out how much amps I will be drawing from my alt. for the stereo using the given hardware in my previous post -- if someone would be kind enough to calculate that for me it would be great.
Thx 2 All Who Posted!

Actually, that is like the ol myth that under powering your speakers can cause them to fail, if this was true, we would blow speakers and subs everytime we turned down our HU. It is good to have a little more power than not enough, but it is not for the purpose of maximizing the performance of the speaker/sub. In my experiences, it is the enclosure that maximizes the efficiency of the subwoofer moreso than power. If you are running a 500 wRMS sub, in my experiences, it will perform excellent w/ as little as 250 wRMS, and will perform it's best given 500 wRMS. I was running 2 of the Coustic Carbon Fiber 1244's in a sealed enclosure, these subs are rated @ 400 wRMS, I was running them series/parallel for a final impedance of 4ohms, I had a Kenwood 7251 2 channel which is only 460 wRMS bridged, these subs performed great only getting apprx. 230 wRMS ea., just over half their rated power. If you go w/ the Type R 4ohm DVC, you will be fine w/ 300 wRMS, and it will be somewhat better w/ 500 wRMS, 600 wRMS would not be pushing it, but would run the sub harder affecting overall SQ. If you go w/ the Type X, 500-600 wRMS would be fine, I would probably go w/ somewhere around 750-800 myself. I'm not sure of other's opinions, but I personally like to run my subs right around their rated power ratings, give or take a few w's.

Agree with Less as well. More "clean" very low distortion, power to a sub is always better than running less power, but high distortion values to any speaker be it sub or full range, can damage a driver in time.
Can we run a 300 watt sub with 500 watts of clean power? You bet! The sub will love it if the signal is low distortion only only transient peaks reach close to 500 Wrms. I would not advise sending a 500 watt sine wave (test tone) to a 300 watt sub for extended periods of time. That can fry the sub as the sine wave has so much energy in it, compared to typical music signals.
On the other hand, yes a good driver rated at 500 Wrms, can easily perform very well at 100 watts or less of clean power. Just turn down the HU volume control to speaking levels will prove that point. The problem is not low power... it's a low powered amp, pushing high distortion values that can damage a sub.
Hope that clarifies more than confuses,

you can blow speakers with not enough power lessismorespl. How do you think so many people blow speakers with just radio pwr? When you do not have a amp that has enough pwr, you have to compensate by turning the deck up more which will put the deck into clipping, which will kill almost any speaker..
