W12K9D2 V3 12" 4000 Watt Dual 2-Ohm Car Audio Subwoofer+dB25 Amplifier

This bundle matches a high-excursion subwoofer with a compact amplifier that can drive it. The Rockville W12K9D2 V3 is a 12" dual 2-ohm subwoofer rated at 1,000W RMS CEA-Certified (4,000W peak). The V3 upgrade added a competition-grade dust cap, an inner dust cap that reduces voice coil heat buildup, a smaller pole vent for better thermal management, and a voice coil cooling vent. These changes let the sub handle sustained bass-heavy content and test tones better than previous versions.

The Rockville dB25 v2 2-channel amplifier delivers 750W RMS bridged at 4 ohms through a compact Class D chassis measuring 11.26" x 5.51" x 1.97". Wire the W12K9D2's dual 2-ohm voice coils in series to present a 4-ohm load, bridge the dB25 v2, and you get 750W of clean, Dyno-Certified power to the sub. The amp includes a fully adjustable 12dB crossover with low-pass and high-pass filters, a 12dB bass EQ, and IC-controlled protection. A Rockville die-cut decal sticker is also included in the box.
