Product Overview
For a competition SPL build, the Nemesis Audio NA-33T is a 33-inch subwoofer rated for 10,000W RMS. Its Klippel®-optimized motor, 6-inch flat wire voice coil, and 70mm Xmax are designed for high-output use in a purpose-built enclosure.
Dual 1-ohm voice coils can be wired for a 0.5-ohm or 2-ohm final load. Plan the enclosure, amplifier, and vehicle electrical system around this subwoofer before ordering.
Key Features & Benefits
- 33-inch size: The large cone provides substantial cone area for competition SPL builds.
- 70mm Xmax: The stated linear excursion is 2.76 inches for substantial cone travel.
- Klippel® optimization: Laser measurement and optimization focus on linear excursion and distortion across the stroke.
- 6-inch flat wire voice coil: The coil design supports the subwoofer’s stated 10,000W RMS power handling.
- Progressive 5-layer spider: The spider and high-roll sandwich surround help control cone movement across its excursion range.
- Dual 1-ohm coils: Choose a 0.5-ohm parallel or 2-ohm series wiring configuration to match a compatible amplifier.

Why Choose This Product?
The NA-33T combines a fiber-reinforced paper cone, aluminum cast basket, and 30.1 T·m motor strength in a 33-inch driver. Its 24.42 Hz resonant frequency and 70mm Xmax are relevant when planning a competition-focused low-frequency system.
The progressive spider and high-roll sandwich surround are designed to manage cone movement through its stated excursion. Its large size and 10,000W RMS rating make careful system planning essential.
Installation & Compatibility Notes
This subwoofer requires a purpose-built bandpass or ported enclosure designed around its T/S parameters. A generic enclosure is not recommended.
Plan for a high-current mono amplifier rated 8,000–10,000W RMS at 0.5 or 2 ohms. Wire the coils in parallel for 0.5 ohms or in series for 2 ohms, and confirm the chosen load is supported by the amplifier.
The described electrical requirements include a high-output alternator, multiple AGM or lithium batteries, and 0-gauge or larger power and ground wiring. The source also identifies a 250A+ alternator and a Big 3 electrical upgrade as a minimum starting point. Have the complete system and vehicle electrical requirements assessed before installation.
Frequently Asked Questions
What amplifier rating is recommended for the NA-33T?
The stated requirement is a high-current mono amplifier rated 8,000–10,000W RMS at 0.5 or 2 ohms. Confirm that the amplifier supports the final impedance you choose.
How can I wire the dual 1-ohm voice coils?
Wire the coils in parallel for a 0.5-ohm final impedance, or in series for a 2-ohm final impedance.
What type of enclosure does this subwoofer need?
Use a purpose-built bandpass or ported enclosure designed for the NA-33T’s T/S parameters. Do not use a generic enclosure.
What electrical system upgrades are identified for this build?
The stated requirements include a high-output alternator, multiple AGM or lithium batteries, 0-gauge or larger power and ground wiring, and a Big 3 upgrade as a minimum starting point. The product information specifies a 250A+ alternator.

Recommended Monoblock Amplifiers
Power-matched options for one subwoofer or one complete loaded enclosure. We aim to include same-brand choices when their ratings qualify.
Loading amplifier suggestions…
Suggestions use 75–125% of the subwoofer’s RMS rating at the wiring load shown. Check wiring, enclosure needs, electrical capacity and installation space. Set gain and filters correctly to avoid overpowering the subwoofer. Buying more than one subwoofer changes the match.
