Designed for high-output car audio systems, it combines a large motor assembly with a 4-inch, eight-layer voice coil. The 18-inch model needs serious enclosure space: GP recommends a 5.5–7.0-cubic-foot ported design.

The useful comparison is not wattage alone: check usable cabinet volume, port layout, mounting clearance and amplifier compatibility together. GP describes the Undertaker V2 as a collaboration with Jacob Fuller of Sundown Audio; the cooling and motor construction are central features of this design.\u003c\/p\u003e\u003cp\u003eThe RMS rating is a manufacturer specification, not a guarantee of vehicle output, a competition score or immunity from damage. Results depend on the enclosure, installation and system settings.\u003c\/p\u003e\n\u003ch2\u003eInstallation \u0026amp; Compatibility Notes\u003c\/h2\u003e\u003cp\u003eAllow at least the published 14.95-inch mounting depth, then confirm additional clearance needed for ventilation, wiring and internal bracing. The 16.68-inch cutout and 18.46-inch outside diameter must both suit the baffle. A generic box labeled “18-inch” is not sufficient evidence of fit.\u003c\/p\u003e\u003cp\u003eUse GP's 5.5–7.0-cubic-foot ported recommendation and 25–32 Hz tuning range as design inputs, not as a complete cut sheet. Account for the driver's 0.30-cubic-foot displacement, port and bracing when calculating the finished cabinet. GP's product text does not explicitly label its recommended volume as gross or net, so confirm that basis with the enclosure designer before cutting material. No sealed-box recommendation is supplied here.\u003c\/p\u003e\u003cp\u003eHave the installer confirm the finished coil wiring and amplifier's permitted load. Dual 1-ohm and dual 2-ohm are coil ratings, not a single fixed final load for every installation. Plan secure mounting, electrical supply, cable sizing, protection and amplifier settings around the complete system. Do not treat the 5,000W rating as an instruction to apply that power in every enclosure.\u003c\/p\u003e\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\u003ch3\u003eDoes the Undertaker V2 18 include an enclosure?\u003c\/h3\u003e\u003cp\u003eNo. This is a standalone subwoofer listing. The enclosure and amplifier are separate parts of the system.\u003c\/p\u003e\u003ch3\u003eWhich voice-coil option should I choose?\u003c\/h3\u003e\u003cp\u003eChoose dual 1 ohm or dual 2 ohms based on the amplifier's supported impedance and your planned number of drivers. Confirm the complete wiring plan before selecting the variant; the two versions are not interchangeable in every system.\u003c\/p\u003e\u003ch3\u003eWhat box does GP recommend?\u003c\/h3\u003e\u003cp\u003eGP lists a ported enclosure of 5.5–7.0 cubic feet, 16–18 square inches of port area per cubic foot and 25–32 Hz tuning for this 18-inch model.
