Our take on the Rockville Destroyer 15D2 15" Competition Car Audio Subwoofer

The Rockville Destroyer 15D2 is a 15-inch dual 2-ohm car subwoofer built for high-power bass. Rockville rates it at 2,000 watts RMS (CEA), 4,000 watts program and 8,000 watts peak, with 3-inch aluminum voice coils, a triple-stack 300 oz Y35 magnet and a one-piece chrome T-yoke. It suits bassheads building a big ported box for SPL or loud daily systems. Against name-brand competition subs, it leans on heavy motor hardware and high power ratings at a lower outlay, but it needs a strong amplifier and a large enclosure, and it is not a sound-quality-first driver.

About the Rockville Destroyer 15D2 15" Competition Car Audio Subwoofer

The Rockville Destroyer 15D2 is a 15-inch competition car audio subwoofer with dual 2-ohm voice coils. It is rated for 2000 watts CEA RMS, 4000 watts program and 8000 watts peak power handling.

The motor uses 3-inch, 4-layer black aluminum voice coils made in the USA and wound with aluminum wire. They are rated to withstand temperatures of 300-350C. The motor also has triple-stacked 300 oz Y35 magnets and a 1-piece chrome T-yoke with a stamped logo. A high-temperature black glue is used in construction.

The cone is black non-pressed paper, reinforced with silver stitching. It has an extra-thick foam surround, a shiny paper dustcap and a Nomex spider. The basket is cast aluminum with a black sanded finish. Large 8-gauge chrome-plated binding posts handle the connections. A rubber mounting gasket helps with installation, and rubber boot covers protect the magnets.

Questions and answers

How much power does the Destroyer 15D2 need?
Rockville rates it at 2,000 watts RMS (CEA), 4,000 watts program and 8,000 watts peak. Plan on a strong amplifier that stays clean near its RMS rating.
What impedance can I wire it to?
It has dual 2-ohm voice coils, so you can wire them in parallel for a 1-ohm load or in series for 4 ohms. Match that to what your amplifier is stable at.
