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.
The 8” S-Series subwoofers are engineered with an improved voice coil allowing the woofer to benefit from it's power rating of 300 watts. Match them with the powerful VPower MRV-M500 mono amplifier for a great subwoofer system.


Each S-Series subwoofer uses a custom-stamped steel frame. These highstrength frames were designed to withstand the rigors of the improved SSeries 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.
The push-type insert terminals help reduce the installation time of the SSeries subwoofers. Just strip the speaker insulation at the wire end, then insert the bare wire into the hole of the spring-loaded push terminal.


The S-Series subwoofers use two strontium ferrite magnets stacked together, for increased motor strength and excursion which ultimately leads to more bass output.
The S-Series subwoofers have concealed mount gaskets, creating a clean, finished appearance for any vehicle.


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.
