Rockville RG212CA Dual 12" Powered Subwoofer vs Rockville RV12.2B Dual 12" Sub Enclosure Kit

The Rockville RG212CA is the stronger pick for most shoppers. It runs a Class D amp at 500W RMS with a 2-ohm stable load, and its ¾-inch MDF enclosure is ribbed and braced. The RV12.2B is a Class A/B design rated 400W RMS with a 4-ohm load, and it is heavier and bulkier. Owners of the Rockville line praise output for the size; the RV12.2B's angled cabinet and dash bass remote suit tight spaces.

  • Choose the Rockville RG212CA if you want more RMS power, a more efficient Class D amp and a shallower, lighter box that fits behind a seat.
  • Choose the RV12.2B if you want a dash-mounted bass remote, an angled vented cabinet and a 4-ohm load that is easy on many stock head units.

What reviewers say

Rockville RG212CA Dual 12" Powered Subwoofer

Owner feedback on Rockville's powered slim subs is mixed. Many praise the bass gain for the money and the easy all-in-one install, while others report failures and say the real output falls short of the headline wattage.

What people mention
  • Bass outputMixedOwners say it adds real thump for the size, but not the wall of bass the peak rating implies.
  • ReliabilityCriticisedSome owners report the amplifier or subs failing after a period of use.
  • FitPraisedThe shallow enclosure fits behind seats and in trunks where a standard dual-12 box will not.
  • InstallPraisedBuyers like getting subs, amp and wiring together, which simplifies the install.

Rockville RV12.2B Dual 12" Sub Enclosure Kit

Owner feedback on this kit is limited, but what exists centers on strong output for the money and a straightforward install thanks to the included wiring. Complaints tend to focus on the size of the box and on the amp's heat and current draw.

What people mention
  • Bass outputPraisedOwners say the dual 12s deliver deep, strong bass that transforms a factory stereo.
  • InstallationPraisedThe included RCA, power, ground, remote and speaker wires make the install easier than sourcing parts separately.
  • SizeCriticisedThe deep, heavy enclosure eats trunk or cargo space and is awkward to move alone.
  • Amplifier heatMixedThe Class A/B amp runs warm during long, loud sessions, so ventilation matters.

Questions and answers

Which hits harder?
The Rockville RG212CA. It has more RMS power and a 2-ohm stable Class D amp, so it delivers more output from the same electrical supply.
Which is easier to fit in a small car?
The Rockville. Its box is only 4.37 inches deep and weighs less, so it slides behind a seat or into a shallow trunk. The RV12.2B is much deeper and heavier.
Does the RV12.2B sound cleaner?
Not necessarily. Class A/B can sound smooth, but the RV12.2B has lower RMS power and a 4-ohm load. The Rockville's Class D amp is more efficient and stays cooler.
Which lasts longer?
Both use MDF cabinets and similar subwoofer materials. The Rockville's Class D amp produces less heat, which usually helps amplifier life. Keep either one dry and well ventilated.
Is the RV12.2B worth stepping up to?
Only if you want the dash bass remote and the angled cabinet. On power and footprint, the Rockville is the better all-around choice.
