Powerful Low End You Crave in Your Ride

The P2D4-8 is built with a Kevlar fiber-reinforced paper cone, providing accurate and responsive bass reproduction. Its Santoprene surround enhances excursion capabilities, improving low-frequency output and reducing distortion.

Equipped with a hybrid StampCast steel basket, the P2D4-8 ensures stability and durability while maintaining a sleek design. Its proprietary spider venting technology helps to dissipate heat, minimizing power compression and ensuring consistent performance over time.

Whether you want to enhance your car's audio system or add impactful bass to your music, the Rockford Fosgate P2D4-8 offers a reliable and versatile solution. With its solid construction and powerful performance, this subwoofer delivers satisfying low-end frequencies that elevate your listening experience on the road.

Features:

  • Overview: The Rockford Fosgate Punch P2D4-8 is an 8-inch subwoofer with dual 4Ω voice coils. The sub features a StampCast steel frame, quick-release compression terminals, a Kevlar fiber reinforced paper cone, and Santoprene surround. An anodized aluminum voice coil former and spider venting help keep the subwoofer cool.
  • Dual 4Ω Voice Coils: The dual 4Ω voice coils offer wiring flexibility; when wired in parallel the woofer presents a 2Ω load, when wired in series the woofer presents an 8Ω load.
  • Steel Basket: The P2D4-8 subwoofer features a StampCast steel basket for added rigidity.
  • Compression Terminals: The P2D4-8 features spring post terminals which accommodate speaker wire up to 10 gauge.
  • CEA-2031 Compliant: Power handling on the P2D4-8 subwoofer conforms to CEA-2031 industry standards. This means the subwoofer has the capacity to handle its rated power under continuous demand, not instantaneous power handling, that over time, can damage voice coils.
  • FlexFit Basket: The Flex Fit frame utilizes slots (where possible) instead of single screw sized holes; allowing slight adjustment of the speaker when mounted.
  • Trim Ring: To improve the cosmetic look, a decorative trim ring is included that mounts over the flange of the woofer. When using the cast aluminum trim ring the woofer is first mounted with four screws, then the ring is placed on top of the woofer, aligning the final four holes of the woofer with ring. The other four screws are used for these holes to mount the ring and woofer to the enclosure. Without the trim ring the mounting height of the woofer is approximately 7/8 of an inch.
  • Sealed Box: Rockford recommends a sealed enclosure with an optimum internal volume of 0.23 cubic feet (from 0.2 to 0.3 cubic feet is acceptable). Sealed enclosures provide the most control over a woofer, will handle a lot of power, and provide accurate sonic reproduction, making them suitable to all types of music.
  • Ported Box: Rockford recommends a ported enclosure with an internal volume of 0.65 cubic feet using one 2" diameter x 8" long port; this yields a tuning frequency of 38.5 Hz. Ported (or vented) enclosures typically provide better overall efficiency than sealed so they are suitable for use with smaller amplifiers, giving you more bass output from less power. However, this efficiency comes at the expense of very low frequency output (below 33 Hz).

  • These subs are crazy good, man! Amazing performance for their size – I push 300 watts RMS at them, 4 ohms, and they handle it like champs. Plus, they look super good. They pack a ton of sound in such a small package. In any genre, I like it loud always, and after years of daily use, this sub only gets louder. Its way better than I expected!

  • I had to try out this cool looking sub and was immediately in awe with how good it sounds for its tiny size. Lovely addition to my sound system.
