2) Alpine S-W12D4 12" 1800 Watt Dual 2-Ohm Car Audio Subwoofers DVC Subs SW12D24

Description:

The S-Series subwoofers are designed with increased bass output and installation versatility

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-Series subwoofer uses a custom - stamped steel frame. These high-strength frames were designed to withstand the rigors of the im proved 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-Series 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.
