I've owned the p3's in 10s and 12s and they are loud with good sq. I also run rockford amps on all my systems. You can def tell a difference between RF amps and another brand. Most brands overate there wattage and don't come with a real birth sheet of their products like RF, they may be pricey but not ridiculous, i guess u get what u pay for? PS i liked the look of the older models.
