Cools...Looks like we have a winner!
Thanks of your guys' input!
Now I think I will just replace the rear speakers too and put up with my sub/amp setup until I cant take it anymore.. Hehehe...
Now which ones should I get for the rear fill?

Or you meant to power the fronts by bridging the firs two channels and then bridge channels 3 & 4 to power the subs?
Thanks.

There's 2 ways to blow a speaker
1. mechanically
2. thermally
clipping cannot damage an amp (thats assuming your amp is decent and not a brand new $69 + free shipping 5 channel that does 100 x 4 + 400 x 1 off ebay ) since they are designed to not cook themselves at that point.
now, what clipping does is "chop" the top and bottom of the wave making it square. some will tell you that "square wave" will damage the speaker, regardless of any other conditions. clipping an amp or speaker, normally, will not damage anything.
so what kills speakers? overpowering them mechanically or calling them to do things they can't for too long a time. overheating the coil beyond its capability(thermally) is the short answer. the "RMS rating" is only a thermal guideline determined by limited testing, after all. if you give a "500w" speaker "500w" it's fine. the problem comes when you overdrive the amp through a non-judicious use of the gain and volume *****. that square wave with the tops missing...the position of the wave moves towards the upper and lower limits making the amplitude larger [the wave appears wider, that is, more "info" the amp has to reproduce]...therefore requiring more from the amp...and letting the magic smoke out of the speaker.
you basically need to overrun the limits of the speaker. drivers can be overpowered, safely, if you're careful. it's pushing the volume up "those last 2 notches on that one song" which might kill the speaker. also, clipping damage may not be instant depending on how hot the voice coil is.
hope that wasn't too long winded here's the long version if you'd like to peruse it http://www.bcae1.com/2ltlpwr.htm the very last line way at the bottom is crucial

Correct me if I am wrong. So according to what I read from the link, it is actually "good" to have an amp that is rated above the rated power the speakers can handle. Since the amp can deliver more power to the speakers(even at the speakers max), if I some how turn the volume too high I will still get a pure sine wave coming from the amp which is "clean" and not clipped.
And in my case, bridging channels 1&2 of the Soundstream amp to run the Focal components will yield a RMS power of 460 RMS (230 RMS to ea. speakers). So even if I push my speakers to its 150 RMS max the Soundstream amp will not even break a sweat delivering 150 RMS therefore not sending clipped sine wave or even worst, square waves.
Since I dont blast out my music with my windows down, I am safe with having an amp well capable of delivering a lot of power than my speakers can handle..I listen to my music with my windows up..

Yes, it's good to have more RMS in your amp than your speakers can handle. Your amp doesn't have to work at hard, so it stays cooler, and since it stays cooler there's less distortion as well.
...Just so long as you're not cranking the gains so high that you're overpowering the speakers.

HOw about the amp kit?
I see the ones that are brand named and the ones that are not. Do you guys have some preference or I should just get a generic one?

I used a Tsunami branded one, the wires are very flexible, particularly considering how thick they are. I think the major difference between different brand kits are the quality of the terminals/connectors. Wire's pretty much wire.
Obviously avoid anything with bad reviews, but copper is copper.
