Description
15" 2-Ohm DVC Punch P2 Subwoofer 400W RMS, Kevlar Cone, VAST, Dual Spider, Diamond-Cut Cast Aluminium Trim Ring, Extended Pole Piece.
Product Overview
The Rockford Fosgate Punch P2D2-15 is a 15" 2-Ohm Dual Voice Coil (DVC) subwoofer rated at 400W RMS the largest format in the Punch P2 range. The 15" cone moves significantly more air than the 10" and 12" P2 models, producing the greatest bass output and lowest frequency extension in the P2 series. The 2-Ohm DVC provides wiring options of 1-Ohm (parallel), 4-Ohm (series), or 2-Ohm per coil for bi-amplification. Optimised for sealed and vented enclosures. Sold as an individual unit.
A 15" subwoofer requires a substantially larger enclosure and installation space than smaller formats. Confirm enclosure volume requirements, mounting depth, and available boot or cargo space from the official Rockford Fosgate P2D2-15 datasheet before purchasing.
All confirmed Punch P2 construction applies: Kevlar fibre-reinforced paper cone, VAST surround (up to 25% increased cone area), high-temperature voice coil with Nomex® reinforcement collar, dual linear spider, extended pole piece with bumped vented backplate, StampCast basket with integrated spider venting, diamond-cut cast aluminium trim ring with grille provision, and protective PVC textured magnet cover.

Features & Benefits
-
15" Cone — Maximum P2 Air Movement — The 15" format produces the greatest bass output and lowest frequency extension in the Punch P2 range. A 15" driver requires a substantially larger enclosure — confirm dimensions and installation space before purchasing.
-
400W RMS — Confirmed 400W RMS — the same power rating as the P2 12" models, reflecting the scaling of the larger motor to match the 400W tier across the P2 range.
-
2-Ohm DVC — Three Wiring Options:
-
1-Ohm (parallel): Both coils in parallel — confirm amplifier stable at 1-Ohm before use
-
4-Ohm (series): Broad amplifier compatibility
-
2-Ohm per coil (biamp): Separate amplifier channels
-
Dual Linear Spider — Improved suspension compliance and cone control at high excursion.
-
Kevlar Fibre-Reinforced Paper Cone with VAST — Kevlar stiffness and breakup resistance plus up to 25% increased effective cone area.
-
Nomex® Voice Coil Collar — Thermal and mechanical reinforcement at the voice coil-to-cone junction.
-
Extended Pole Piece and Bumped Vented Backplate — Extended pole for increased Xmax; vented backplate eliminates air spring compression.
-
Diamond-Cut Cast Aluminium Trim Ring — Premium machined aluminium finish with grille insert provision.
-
StampCast Basket with Integrated Spider Venting — Motor cooling during sustained operation.

Compatible With / Goes Well With
Suitable enclosure types:
- Sealed and vented — both confirmed
Wiring:
- 1-Ohm → parallel (confirm amplifier stability)
- 4-Ohm → series
- 2-Ohm per coil → biamp
Pairs well with:
- Rockford Fosgate T1500-1BDCP or T2500-1BDCP mono amplifiers — confirm RMS output at intended impedance matches 400W
Frequently Asked Questions
Does a 15" P2 subwoofer fit in a standard car boot?
A 15" driver and its required sealed or vented enclosure occupy significantly more space than a 10" or 12" installation. The P2D2-15 is best suited to vehicles with dedicated boot space, custom enclosure builds, utes, vans, or trucks. Confirm the enclosure dimensions against available installation space before purchasing.
What amplifier power is appropriate?
400W RMS at the selected wiring impedance. Confirm the amplifier's RMS output at 1-Ohm (parallel), 4-Ohm (series), or 2-Ohm per coil before purchasing.
What enclosure volume is required?
Enclosure volumes are not confirmed in the supplier data. A 15" driver requires considerably more net internal volume than 10" or 12" formats. Pull the official Rockford Fosgate P2D2-15 datasheet for sealed and vented recommendations.
Is a grille available?
The diamond-cut cast aluminium trim ring accommodates an optional grille insert. Confirm the compatible SKU with Rockford Fosgate.
What terminal type does the P2D2-15 use?
The features list states "nickel plated push terminals." The P2D4-10 spec table indicates "compression terminals" — a conflict present across the P2 range. Confirm with Rockford Fosgate across all P2 subwoofer models simultaneously.
