Alpine S-W12D4 12″ S-Series Dual 4-Ohm Car Subwoofer

The Alpine S-W12D4 is a newly released S-Series subwoofer with lots of technical improvements. It sports 1800 watts of power with a Dual 4-ohm impedance. Elegant looking 12 inch diameter will surely provide you the bass you need.

Great bass in less space

To create great bass, you need the best materials and engineering. Alpine’s S-Series subwoofers apply technology from their higher end subs to bring you the depth as well as punch that will make your tunes come alive. To make things even better, these subs are about an inch shallower than their predecessors, making them great candidates for locations where regular high-power subs won’t fit.

Advanced materials

The S-W12D4 12″ sub can handle up to 600 watts RMS, so you can drive it hard without any worries. The tough Kevlar® treated cone stays rigid under pressure, while its rubber High Amplitude Multi-Roll (HAMR) surround enables maximum excursion for impressive performance. Its dual 4-ohm voice coils allow for extra wiring flexibility, which helps if you plan on adding another subwoofer down the line. Also, it rocks in both sealed and ported boxes, so you can choose an enclosure that suits your tastes.

Versatile Applications

Along with the new 8” woofer, the 10” and 12” S-Series subwoofers have been re-designed from the ground up. The mounting depth of the 10” and 12” subwoofers are almost 1” more shallow than previous models at just over 4.5” for the 10” models and just over 5” for the 12” models, allowing them to fit into a wide variety of installation applications.

600W Power Handling

The 10” and 12” S-Series subwoofers are engineered with an improved voice coil allowing the woofer to benefit from an increased power rating of 600 watts. Match them with the powerful VPower MRV-M500 mono amplifier for a great subwoofer system.

Custom-Stamped Steel Frame

Each S-W12D4 subwoofer uses a custom-stamped steel frame. These high-strength frames were designed to withstand the rigors of the improved S-Series motor. They have frame leg vents as well as a vented back plate to help cool the subwoofer voice coil and motor parts, plus a shallow design to help fit in smaller spaces.

Push-Type Insert Terminals with Dual Voice Coil Jumper System

The push-type insert terminals help reduce the installation time of the S-Series subwoofers. Just strip the speaker insulation at the wire end, then insert the bare wire into the hole of the spring-loaded push terminal.

Strontium Ferrite Double-Stacked Magnets

The S-W12D4 subwoofers use two strontium ferrite magnets stacked together, for increased motor strength and excursion which ultimately leads to more bass output.

Clean, Concealed Mount Gasket System

The S-Series subwoofers have concealed mount gaskets, creating a clean, finished appearance for any vehicle.

Optional Grilles

All S-Series subwoofers are compatible with optional grilles (sold separately) to provide added protection to the cone. The grilles feature a mesh design with a S-Series logo badge. Choose from the following to match the size of your subwoofer; all grilles are sold as single pieces.

  • KTE-10G.2: For 10” S-Series Subwoofers
