Our take on the Rockville DK512 PACKAGE Dual 12" 2800w K5 Car Subwoofer Enclosure+DB12 Amplifier

This is a bundled bass package: a loaded dual 12-inch vented enclosure plus Rockville's DB12 monoblock amplifier. The enclosure is built from 3/4-inch MDF, braced and stapled, with two 2-ohm subwoofers rated 700 watts RMS (2800 watts peak) and tuned to 35 Hz. It suits shoppers who want a complete, pre-matched bass setup for a trunk or hatch without choosing subs, box and amp separately. Against buying components piece by piece, it saves matching work but locks you into Rockville's tuning and amp pairing.

About the Rockville DK512 PACKAGE Dual 12" 2800w K5 Car Subwoofer Enclosure+DB12 Amplifier

The enclosure is a ported box built from 3/4" MDF that is bonded, stapled and braced. It is covered in tweed carpet and has satin nickel push terminals for speaker wire. The vents are angled at 15%.

Each 12-inch subwoofer has a 2" 4-layer black aluminum voice coil wound with OFC copper wire. It also has a 50 oz magnet, a cast iron basket with a black sanded finish and a fiber-reinforced paper cone. A thick foam surround, a polypropylene dust cap and gold-plated spring-loaded push terminals complete the build. A vented hole in the T-yoke helps dissipate heat, and a branded mounting gasket helps with installation.

The amplifier is a mono Class D design rated for 2 ohm loads. It has under-voltage protection at 10V and over-voltage protection at 16V. It uses an 80 amp Maxi fuse.
