Prodigy Audio NB2 Series
The Prodigy NB2 Series gives customers three useful woofer sizes while keeping the power requirements reasonable enough for practical daily systems.
- NB2-8D4: 8-inch, 300 watts RMS, dual 4 ohm
- NB2-10D4: 10-inch, 350 watts RMS, dual 4 ohm
- NB2-12D4: 12-inch, 400 watts RMS, dual 4 ohm
All three models use a dual 4-ohm voice-coil configuration, giving installers multiple wiring options depending on the number of subwoofers and amplifier being used.
Prodigy NB2-8D4 8-Inch Subwoofer – 300 Watts RMS
The Prodigy Audio NB2-8D4 is the compact member of the NB2 family. It is an 8-inch dual 4-ohm subwoofer rated for 300 watts RMS.
An 8-inch woofer can be a great choice when installation space matters. Smaller enclosure requirements can make an 8-inch system easier to fit into trucks, compact cars, custom center consoles and other installations where a larger subwoofer and box would take up too much usable room.
The NB2-8D4 has a listed mounting depth of approximately 5 inches, making it considerably easier to package than many larger traditional subwoofers.

Prodigy NB2-10D4 10-Inch Subwoofer – 350 Watts RMS
The Prodigy Audio NB2-10D4 steps up to a 10-inch cone and 350 watts RMS while maintaining the dual 4-ohm voice-coil configuration used throughout the NB2 lineup.
A 10-inch subwoofer is a strong middle-ground choice when you want more cone area than an 8-inch sub while still keeping enclosure size manageable.
Ten-inch subwoofers work well for:
- Daily-driver bass systems
- Truck boxes
- Smaller trunks
- Single-subwoofer systems
- Dual 10-inch systems
- Installations where a 12-inch enclosure would take up too much space
The NB2-10D4 has a listed mounting depth of approximately 5 5/8 inches.
Compare it with other 10-inch car audio subwoofers available from Audio Sellerz.
Prodigy NB2-12D4 12-Inch Subwoofer – 400 Watts RMS
The Prodigy Audio NB2-12D4 is the largest NB2 model, combining a 12-inch cone with a 400-watt RMS rating and dual 4-ohm voice coils.
Twelve-inch subwoofers are one of the most popular choices for daily car audio because they provide more cone area and low-frequency potential while still fitting into practical single and dual-subwoofer enclosures.
The NB2-12D4 is a strong direction for customers who want more bass presence than the smaller NB2 models without moving immediately into Prodigy's higher-power subwoofer families.
Its listed mounting depth is approximately 6 3/4 inches.
Compare additional 12-inch car audio subwoofers if you are deciding between different power levels and system designs.
NB2 8 vs 10 vs 12-Inch Subwoofers
The best NB2 size depends on your available space and bass goals more than anything else.
Choose the NB2 8-Inch When:
- Enclosure space is limited
- You are installing in a truck or compact vehicle
- You want the smallest NB2 option
- A 300-watt RMS subwoofer matches your system goals
Choose the NB2 10-Inch When:
- You want more cone area than an 8-inch sub
- You still want a reasonably compact enclosure
- You are planning a 350-watt RMS daily bass system
- You want a balance between enclosure size and output potential
Choose the NB2 12-Inch When:
- You have enough room for a larger enclosure
- You want the most cone area in the NB2 lineup
- You want the 400-watt RMS NB2 option
- You are building a single or dual 12-inch daily-driver system
Built for More Than Just an Entry-Level Price
Although the NB2 sits at the starting end of Prodigy's subwoofer lineup, the construction includes several features normally associated with more serious aftermarket woofers.
NB2 Series construction includes:
- Double-stacked magnet structure
- High-temperature four-layer copper voice coil
- 2-inch black aluminum voice-coil former
- Up to 14 mm of one-way linear Xmax
- Center pole ventilation
- Radial back-plate cooling holes
- Durable foam surround
- Paper cone
- Stamped steel frame
- Chrome push terminals
- Stitched tinsel leads
Cooling around the voice coil is especially important because heat is one of the enemies of any subwoofer. The center pole vent and radial cooling openings are designed to move heat away from the coil area while the woofer is operating.
Dual 4-Ohm Voice Coils
Every current Prodigy NB2 model uses a dual 4-ohm voice coil.
That matters because the voice-coil configuration determines what final impedance the amplifier will see.
A single dual 4-ohm subwoofer can commonly be wired to either a 2-ohm or 8-ohm final load. Two matching dual 4-ohm subwoofers can commonly be configured for a 1-ohm or 4-ohm final load, depending on how the coils and woofers are wired.
Before choosing your amplifier, use our subwoofer wiring diagrams and final ohm-load guide to determine the correct configuration.
Match the NB2 With the Right Amplifier
Do not choose an amplifier by looking only at maximum or peak wattage.
Start with the RMS rating of the subwoofer:
- NB2 8-inch – 300 watts RMS
- NB2 10-inch – 350 watts RMS
- NB2 12-inch – 400 watts RMS
Then calculate the final impedance of the completed subwoofer system and compare it with the amplifier's RMS output at that load.

Single vs Dual Prodigy NB2 Subwoofers
Single NB2 System
A single NB2 subwoofer is a simple way to add real bass to a daily driver without requiring a huge enclosure or extremely large amplifier.
Single-sub systems can be especially useful when trunk space, electrical demand or budget are important considerations.
Dual NB2 System
Two matching NB2 subwoofers provide more total cone area and greater output potential, but they also require additional enclosure space and amplifier power.
Because the NB2 uses dual 4-ohm coils, two matching woofers can also create useful final impedance options for many common monoblock amplifiers.
Calculate the final load before buying the amplifier instead of purchasing everything separately and trying to make the combination work afterward.
Choose the Right Subwoofer Box
The enclosure is a major part of the completed bass system.
Do not buy a box based only on whether an 8-inch, 10-inch or 12-inch woofer physically fits into the cutout.
The enclosure should also account for:
- Recommended airspace
- Subwoofer displacement
- Mounting depth
- Sealed or ported design
- Port area and tuning when applicable
- Number of subwoofers
- Available vehicle space
Read our subwoofer box guide for help understanding sealed, ported and other car audio enclosure designs.
Who Should Buy Prodigy Audio NB2 Subwoofers?
The NB2 Series makes the most sense for someone looking for a practical aftermarket bass upgrade instead of an extreme high-power system.
Consider the Prodigy NB2 if you are building:
- Your first aftermarket subwoofer system
- A daily-driver bass upgrade
- A compact truck system
- A single-subwoofer system
- A moderate-power dual-subwoofer system
- A system where a huge electrical upgrade is not part of the plan
- A budget-conscious build that still uses a purpose-built aftermarket subwoofer
NB2 vs Other Prodigy Audio Subwoofers
Prodigy offers multiple subwoofer families for different applications.
The NB2 Series is the practical daily-driver starting point. Other Prodigy families provide options for shallow installations and significantly higher-power systems.
If you need a different mounting depth or more power handling, browse the complete Prodigy Audio subwoofer lineup before choosing the final woofer.
Complete the Installation
A subwoofer cannot perform correctly without the rest of the system.
A complete NB2 installation may require:
- A properly matched monoblock amplifier
- The correct sealed or ported enclosure
- Properly sized power and ground wire
- Speaker wire
- Fuse protection
- A solid amplifier ground
- Correct final impedance
- Proper amplifier gain and crossover settings
Shop car audio amplifier wiring kits and car audio power, ground and speaker wire to finish the installation correctly.
Prodigy Audio NB2 FAQ
How much power do Prodigy NB2 subwoofers handle?
The current NB2 lineup includes an 8-inch model rated at 300 watts RMS, a 10-inch model rated at 350 watts RMS and a 12-inch model rated at 400 watts RMS.
What ohm are Prodigy NB2 subwoofers?
The current NB2-8D4, NB2-10D4 and NB2-12D4 models all use dual 4-ohm voice coils.
What sizes are available in the Prodigy NB2 Series?
The NB2 Series is currently offered in 8-inch, 10-inch and 12-inch sizes.
Can I run one Prodigy NB2 subwoofer?
Yes. A single NB2 can be used in a properly designed single-subwoofer system with an amplifier matched to the woofer's RMS rating and final wired impedance.
Can I run two Prodigy NB2 subwoofers?
Yes. Two matching NB2 subwoofers can be used together as long as the enclosure is designed for both woofers, the final impedance is compatible with the amplifier and the amplifier provides appropriate RMS power.
What amplifier do I need for a Prodigy NB2?
Choose the amplifier based on the exact NB2 model, number of subwoofers and final impedance. Compare amplifier RMS output at the final load with the combined RMS requirements of the subwoofers.
Is the Prodigy NB2 good for a daily driver?
The NB2 Series is a strong fit for daily-driver systems where the goal is real aftermarket bass with moderate power requirements rather than an extreme high-output build.
Should I get the NB2 8, 10 or 12?
Choose the 8-inch when space is the biggest concern, the 10-inch when you want a balance between enclosure size and cone area, or the 12-inch when you have more enclosure room and want the largest and highest-powered option in the NB2 lineup.
Does the Prodigy NB2 need a high-output alternator?
Not automatically. Electrical requirements are determined by the complete amplifier system, vehicle charging capacity and how the system is used. A moderate-power NB2 system generally places much less demand on the vehicle than a multi-thousand-watt bass system.
Why Buy Prodigy Audio NB2 Subwoofers from Audio Sellerz?
Audio Sellerz works with real car audio systems ranging from simple first-time bass upgrades to custom enclosures and high-output builds.
We understand that the best subwoofer is not always the largest or highest-powered one. The woofer needs to make sense for the vehicle, enclosure, amplifier, wiring, electrical system and the customer's actual bass goals.
