Sold by AudioSellerz.com

The Prodigy Audio NB3-12D4 12" 800 Watt RMS Dual 4 Ohm Shallow Mount Subwoofer is a NB3 shallow-mount car audio subwoofer rated at 800 watts RMS with a dual 4 ohm voice-coil configuration. It is designed for truck systems and compact builds that need 12-inch cone area with far less mounting depth than a traditional full-depth subwoofer.

This page includes the published fitment and T/S information needed to plan the amplifier, final ohm load, enclosure, speaker wire, and electrical support. Match the subwoofer from continuous power and real impedance—not from peak wattage alone.

Match the Subwoofer, Amplifier, and Enclosure

The amplifier must provide appropriate RMS output at the final wired load. The enclosure must fit the exact subwoofer's air-space, mounting-depth, cutout, displacement, excursion, and intended response requirements. A random box can limit output or control even when the subwoofer and amplifier are good.

Frequently Asked Questions

What amplifier should be used with this subwoofer?

Match amplifier RMS output to the subwoofer's continuous rating at the final wired impedance. Leave room for clean tuning and set gain correctly instead of relying on maximum-power numbers.

Why does voice-coil configuration matter?

The voice coils and wiring method create the final impedance seen by the amplifier. The final load must remain within the amplifier's rated operating range.

Can this subwoofer use any box?

No. Verify mounting depth, cutout, driver displacement, recommended air space, enclosure type, port requirements when applicable, and vehicle space before building or ordering an enclosure.
