Between Infinity Kappa Perfect 10.0 or JL audio W3v3 10" subs
My box is the subthump (6 1/8" M/D) and it will be housing 2 10's.
I'm using an Eclipse XA4000 to push 350w at each sub.
Thanks, Brad

10W3V3s aren't that expensive.... I've worked in a bunch of audio places and JL subs are one of the few products out there that you actually get what you pay for. I don't relly like thier amps, but I haven't found any amp I like better than Zapco..
IMO the W6V2s are the best subs on the market for the average guy. I've had W7s, but I still like the W6V2s the best....

Isn't the airspace going to be too small for those subs? I've actually heard good things about the Elemental Designs subs that subthump recommends for their boxes. They require .5 cu. ft. and are rated at 500 watts rms.

that's 'cause you've never messed with Audison!!

That's another thing I'm curious about. Help me figure this out. Comparing 2 different subs. One has 150W RMS and the other has 300W RMS. MY amp puts out a constant 150W to a sub. The problem is that the sub that handles the 150W requires 1.0 cubic ft. per sub and the 300W sub is good at .6 cubic ft. IS it better to not have enough room, but enough power, or the right size enclosure and not enough power?

I would go for the sub that fits the box's airspace. You'll be okay with the lower power. You just won't be able to play as loud as you could with the 300 watt amp. Think about it like this; the sub is going to receive the same amount of power at low to mid volumes with either amp. The 150 watt amp might start clipping at say volume 20 when the 300 watt amp might start clipping at volume 30. Make any sense?
Maybe this will help. I drew a graph showing a sine wave of an amplifier's output. For distortion-free sound, you want the wave to be smooth. Notice the blue line has reached it's maximum output at the certain volume level and it is flat at the peak of the wave. This is what distortion looks like on paper when an amp is "clipping". If you were to lower the volume level, both sine waves would be equal thus producing distortion-free sound.

So, my amp (Eclipse XA5000) is 50x4+300x1 would power 2 JL audio W3v3 10" subs that have a rating of 300W RMS? Would they sound good, given the right enclosure with this amp?

Yeah, the subs would sound fine. I don't know how much "booming" you plan on doing but with the box and subs, I think you'll have plenty of bass. With the sub channel on your amp running 2 ohm mono, you can plan on it putting about 225 watts rms to each sub (wire the positive of each speaker together to form one positive wire and run that to the positive subwoofer output. do the same with the negative.).
However, depending on how high quality sound you want out of the rest of your speakers, I'd consider a different amp. Your amp is a class D which is known to be a "subwoofer only" amp since the power output isn't the cleanest. Use this amp for the subs and buy a different 4 channel Class A/B amp for the rest of the speakers.
