Description of S-W8D4:

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

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.

POWER HANDLING
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.

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.
