You're actually missing the most important number, a value called RMS. Knowing the peak power handling (800watts) doesn't help find an amplifier, as an amplifier with 1000 watts peak power might only put out 200 RMS.You really want an amplifier that can put out more like 300-400 watts RMS @ 2 Ohms, and connect the two speakers in parallel (positive to positive, negative to negative), that'll give you the most volume.Something like the MTX 421D might do it..

Wow, is that sensitivity rating correct? In the communications world, 93dB is one heckuva "big" signal!

In the communications world, 93dB is one heckuva "big" signal!Yup, the 10" Sony P5's have a rating of around 92db I think.. Designed to put out more with smaller amps.And yeah, an amp that size should work well with two 12" subs.
