A P3 15 is sold as P3D2-15 (dual 2-ohm voice coils) or P3D4-15 (dual 4-ohm voice coils), and that suffix decides the amp load. Both are 600W RMS subwoofers. A single P3D2-15 can be wired to 1 or 4 ohms; a single P3D4-15 can be wired to 2 or 8 ohms. The picks below are chosen for about 600W RMS at one of those final loads—select the line that matches the coil version printed on your subwoofer.

Buying tips
- Find P3D2-15 or P3D4-15 on the basket label before buying the amplifier.
- Never wire a P3D4-15 to an amp that is only stable at 1 ohm; its usable single-sub loads are 2 or 8 ohms.
- Use a correctly sized enclosure and set the subsonic filter for ported boxes; the amp alone cannot protect the driver from a bad setup.
