I'm looking for a single 15" or 12" subwoofer for high SPL and some SQ.  I'm planning on building a ported box and I don't want to take up a lot of trunk space so I'm looking for a single woofer. 

My amp outputs 800RMS at 4ohms bridged but it's not operating at full capacity right now since my alternator only outputs 70amps.  An alt replacement is soon to come.

I'm looking for at a price range of $150-250.  I'm currently devating between two RF subs; the P215s8 and the P315D2.  I want to go with the P2 because WinISD does not show a considerable SPL difference between the two.

If you want more SPL at lower volume you should pick a subwoofer with a higher SPL value at 1W right.

For the power you have I would recomend the Kicker L5 12 or 15
We just installed a 12" L5 in a durango this last weekend, and it was being powered by a Kicker zr600 (600WRMS@4OHM)
It was capable of hitting 143.6db @ 45hz with a completly streetable setup.

depends on box and power.     on lower power the l5's will be louder approx 1000 and lower the L5's will be louder.
1000 up per sub the L7 will start to show.
I only noticed a gain using the L7s when I was getting over 1500 per sub...then I was starting to have issues with the L5's holding up for long peroids of time
The L7's I run normally at 3300 per woofer, and thats on 10's
Just remember I only give my equipment a 2 second burst then its done.
For street use right now I have a single ZX1500 running on 18 volt at 1 ohm....No you cannot run these amps this way out of the box, I had to special order mine from kicker, but That runs about 1100 per woofer for street use
