Subwoofer Features

ADD BASS TO PRACTICALLY ANY VEHICLE

Don’t think you have room for a subwoofer? Think again. The new S-W8D2 and S-W8D4 8” S-Series subwoofers have a shallow mounting depth of just 3-3/4” and can be used in a sealed box enclosure as small as .15 cubic foot. It is perfect for under seats, behind rear bench seats in trucks, or even in some door 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 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-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.
 
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.
