Really? hmmm, so if the Type R (10") is rated at 500 watts, and the ported box that I'm looking at is the max volume rating for it, would that cause any problems?

From my other thread about asking whether I needed another amp to power a woofer, here is what I'm looking at now based upon recommendations by Alien Mantis. I would run the Eclipse XA1200 from the pre-outs on my current Eclipse amp. He also suggested setting the amp for 2 ohms:

probably not, as long as you keep with the Alpine reccomendations it should be fine... Companies make recommendations so that customers won't be blowing subs left and right....

If you stray from those recommendations however you may start to run into mechanical limitations of the moving parts... if you start hearing a slapping noise (like metal on metal or a hammer) at all you need to turn it down ASAP. i'm not sure if you'd head the former slap the back plate first, or if the spider would start to tear first.

be nice to the sub, listen for distortion, distortion is your best warning that your sub is running out of steam.

I have reached another milestone!!! All four doors are now sound deadened!!!! Woohoo!!! Pic's are still on the camera, I'll download and post them up later. I used up all my RAAMmat, but I have a ton of Ensolite leftover, so next I will lay the foam on top of the RAAMmat in the trunk area in preparation for whatever subwoofer I end up with. Waay back at the begining, I only did the RAAMmat in the trunk, not knowing how much Ensolite I was going to use for the doors and under the rear seat. I ended up buying more Ensolite, so now I have PLENTY to do the trunk.
