Which Rockford Fosgate Prime should I choose?

For speakers, your starting point is the size of your car's existing speaker openings — the Prime range covers 4 inch, 5.25 inch, 6.5 inch, 6.75 inch, 6x8 inch, and 6x9 inch. Where two options share the same size, the 6x9 inch R169X3 is a 3-way design adding a Piezo midrange driver to the silk dome tweeter, while the R169X2 keeps things simpler with a flush-mounted 0.5 inch silk dome tweeter and an integrated high-pass crossover.

For amplifiers, the two mono Class-D units — R2-250X1 at 250W RMS and R2-750X1 at 750W RMS — are intended for subwoofer use. The R2-500X4 is the choice for powering front and rear speakers from a single unit, delivering 75W x 4 at 4 ohms, or 250W x 2 when bridged.
