Product Description
ROCKFORD FOSGATE P1S4-10 - 4-Ohm Voice Coil, 250 Watts RMS
Rockford Fosgate P1 10" are the first in a family of world famous subwoofers called "The Punch". During their inception in the 1980's, they quickly became "The Woofer of Choice" for fanatic car audio systems, with a continued tradition today. Kevlar fiber reinforced paper cones deliver bass impact you can feel, and our VAST technology increases surface cone area up to 25%. Best in standard sealed and vented enclosures. Includes soft touch ABS tri trim ring.
Rockford Fosgate P1 10” is the first in a family of famous “Punch” subwoofers. The P1S4-10 features a 4-Ohm voice coil, 250 Watts RMS power handling, and can accommodate a grille insert using the included soft touch ABS trim ring.

Anodized Aluminum Voice Coil Former
Rockford Fosgate subwoofers use anodized aluminum voice coil formers that provide superior heat dissipation (up to 100° at full power levels). Unlike traditional plastic substitutions, aluminum acts like a heat-sink to quickly dissipate thermal build-up on the voice coil. This keeps subwoofers cool during high SPL conditions.
Two things generally happen when voice coils heat-up.
- They can generate heat close to the melt-down temp of their adhesive bonds which leads to eventual failure.
- Voice coil dc resistance increases and reduces SPL output.
Solution... Rockford Fosgate subwoofers use aluminum formers or voice coils for their excellent heat dissipation and SPL capabilities unlike many other plastic substitutes.
Stitched Tinsel Leads
Improved reliability and performance by reducing fatigue and possible shorting.
Multipoint "periodic" stitched lead wire technique reduces the mass of each tinsel lead and spreads stress and strain over a greater area, significantly improving the reliability and performance of the subwoofer.
These stitched tinsel leads withstand extreme duty cycles, fatigue and high current that is critical to robust design.
Flex Fit Basket - Subwoofer
The slot mounted frame pattern allows fine-tuning of the subwoofer's mounting position.
The Flex Fit frame utilizes slots (where feasible) instead of single screw sized holes. This allows slight adjustment of the speaker when mounted.
CEA-2031
Power handling on Rockford Fosgate speakers conform to CEA-2031 industry standards. This means your speaker has the capacity to handle power under continuous damand, not instantaneous power handling, that over time, can damage voice coils.
