Our take on the Rockville RV8.2 8" Car Subwoofer 400 Watt 8 ohm plastic cone

The Rockville RV8.2 is an 8-inch raw subwoofer driver rated at 400 watts RMS with an 8-ohm voice coil and a plastic cone. It is sold as a component for building or repairing a subwoofer enclosure rather than as a finished boxed sub. The 8-ohm impedance is unusual for car audio, where 2- and 4-ohm drivers dominate, so it suits setups that need a higher load or a replacement driver. It is a budget part with modest excursion and power handling next to name-brand 8-inch subs.

Questions and answers

Is this a complete subwoofer or just the driver?
It is a bare 8-inch driver, not a loaded enclosure. You supply the box, wiring and amplifier.
Can I run it on a 4-ohm car amplifier?
Yes, but an 8-ohm driver draws roughly half the power a 4-ohm load would from the same amp. Check your amp's 8-ohm rating before buying.
What size enclosure does it need?
Rockville publishes little Thiele-Small data, so a small sealed box of roughly 0.5 to 0.8 cubic feet is a reasonable starting point. Measure and tune to taste.
Is a plastic cone a problem?
Plastic resists moisture and is durable, but it can be less rigid than treated paper, which may color the sound at higher volumes.
Can I use it as a replacement for a blown factory sub?
Only if the factory sub is also 8 ohm and the mounting depth and cutout match. Check both before ordering.
Where is the Rockville RV8.2 8" Car Subwoofer 400 Watt 8 ohm plastic cone cheapest?
At Rockville, for $19.95, as of our latest check.
