Description
12" 2-Ohm Dual Voice Coil Subwoofer 250W RMS, Mica-Injected Polypropylene Cone, StampCast Basket with Spider Venting, 12 AWG Compression Terminals.
Product Overview
The Rockford Fosgate Prime R2D2-12 is a 12" 2-Ohm Dual Voice Coil (DVC) subwoofer rated at 250W RMS the 12" 2-Ohm variant of the R2 series, sharing the same StampCast construction platform as the R2D4-10. The larger 12" cone moves more air than the 10" model for increased bass output and lower frequency extension; the 2-Ohm DVC coil configuration provides wiring options of 1-Ohm (parallel) or 4-Ohm (series) rather than the 2-Ohm or 8-Ohm options of the 4-Ohm DVC variant. Optimised for sealed and vented enclosures. Sold as an individual unit.
Construction is consistent with the R2 platform: mica-injected polypropylene cone, anodized aluminium voice coil former, linear spider with embedded 16 AWG tinsel leads, StampCast basket with integrated spider venting, 12 AWG compression terminals, and integrated PVC trim ring.

Features & Benefits
-
12" Cone — More Air Movement Than 10" — The 12" cone moves more air per stroke than a 10" driver — producing more bass output and generally extending useful bass reproduction to lower frequencies, particularly in vented enclosures tuned appropriately.
-
250W RMS Power Handling — 250W RMS confirmed. The larger 12" driver handles the same sustained power as the 10" R2D4-10 while producing greater output from its larger cone area.
-
2-Ohm DVC — Three Wiring Options:
-
1-Ohm (parallel): Both coils wired in parallel — produces the maximum output from amplifiers stable at 1-Ohm. Confirm the amplifier is rated stable at 1-Ohm before using this configuration.
-
4-Ohm (series): Both coils wired in series — a safe and widely compatible load for most mono amplifiers.
-
2-Ohm per coil (biamp): Each coil to a separate amplifier channel.
-
Mica-Injected Polypropylene Cone — Mica particles stiffen the polypropylene cone compound for reduced flex and more accurate bass reproduction, with the moisture resistance of polypropylene.
-
StampCast Basket with Integrated Spider Venting — Venting openings in the basket allow airflow around the spider to cool the motor during sustained operation.
-
Anodized Aluminium Voice Coil Former — Anodizing increases the emissivity of the aluminium surface, improving heat radiation from the former into the surrounding air and magnet gap for extended thermal capacity.
-
12 AWG Compression Terminals — Heavier gauge and more secure connection than push terminals — appropriate for the current levels drawn at 250W RMS.
-
Linear Spider with Embedded 16 AWG Tinsel Leads — Consistent compliance across the excursion range; integrated leads reduce failure at the flex point under sustained high-excursion use.
-
Optimised for Sealed and Vented Enclosures — Both sealed and vented enclosure designs are supported.

Frequently Asked Questions
What are the wiring options for the R2D2-12's 2-Ohm DVC?
The 2-Ohm DVC provides three configurations: 1-Ohm (both coils in parallel) for maximum amplifier output where the amp is rated stable at 1-Ohm; 4-Ohm (both coils in series) for broad amplifier compatibility; and 2-Ohm per coil for bi-amplification. Most installers choose between 1-Ohm parallel and 4-Ohm series based on their amplifier's stable impedance rating.
Is the 1-Ohm parallel wiring safe?
The 1-Ohm parallel load is safe for the subwoofer — the subwoofer itself operates correctly at 1-Ohm. The requirement is that the amplifier must be rated stable at 1-Ohm. Many car audio amplifiers are not rated for 1-Ohm operation and will overheat or fail. Always confirm the amplifier's minimum stable impedance before using the 1-Ohm wiring configuration.
What amplifier power is appropriate for the R2D2-12?
250W RMS matched to the wiring impedance selected — 1-Ohm parallel, 4-Ohm series, or 2-Ohm per coil for bi-amp. Confirm the amplifier's RMS output at the selected impedance before purchasing.
What enclosure volume is recommended?
Enclosure volume and vent specifications are not confirmed in the supplier data. Pull the official Rockford Fosgate R2D2-12 datasheet for recommended net internal volumes for sealed and vented configurations.
Does a 12" subwoofer produce more bass than a 10"?
The larger 12" cone moves more air per unit of excursion than a 10" driver. In a matched enclosure, this typically produces more output (louder bass) and lower frequency extension. The practical difference depends on the enclosure design, amplifier power, and room acoustics of the vehicle interior.
