Polk Audio's db Series subwoofers give you trademark Polk performance without stressing your wallet. These subs combine high-tech materials with a laser-optimized motor structure for smooth, powerful bass response.
The db840DVC 8" subwoofer boasts a rigid polypropylene cone and durable Santoprene™ surround built to handle big power over the long haul. The dual 4-ohm voice coils allow you to wire your system to draw maximum power from your mono amp or to safely hook up multiple subs. Match a db sub to a suitable enclosure, and enjoy impressive low-frequency performance rarely found in this price range.
Note: If you are wiring this DVC sub for lower impedance, make sure that your amp is compatible. Most car amplifiers are stable down to 2 ohms in standard mode, or 4 ohms in bridged operation.
To drive this subwoofer, we recommend a mono subwoofer amplifier that can put out between 135 and 270 watts RMS at 2 ohms. For more information please refer to our article on How to Match Subwoofers and Amplifiers.
