Our take on the Sundown Audio SA-12 D4 Classic 12 in 1000W RMS DVC 4-Ohm Car Subwoofers

The Sundown Audio SA-12 D4 Classic is a 12-inch car subwoofer rated at 1000W RMS and 2000W peak, sold here as a matched pair. Each driver uses a dual 4-ohm voice coil, a 2.5-inch high-temperature voice coil, a cast aluminum frame and a 19 mm Xmax for long excursion and deep output. It is aimed at people building a serious bass system who will plan the enclosure and amplifier around it. Against cheaper 12s it trades sensitivity for power handling and excursion, so it needs real amplifier power and a properly built box to perform.

About the Sundown Audio SA-12 D4 Classic 12 in 1000W RMS DVC 4-Ohm Car Subwoofers

The Sundown Audio SA-12 D4 Classic set includes two 12 inch car subwoofers, model SW-SACL12D4, built on the SA Classic platform. Each subwoofer is rated at 1000 watts RMS and 2000 watts peak. Each has a dual 4-ohm voice coil for flexible wiring.

Each driver has a custom 2.5 inch voice coil with high-temperature voice coil wire and a low distortion motor. A large aluminum Faraday ring helps smooth the acoustic response. The 19 mm Xmax gives the cone room to move.

The frame is high strength cast aluminum. The cone is competition-grade paper with a foam surround and a double-layer Nomex spider. Stitched-on XL tinsel lead wires and spring-loaded terminals connect the driver to the system.

Questions and answers

How much power does each SA-12 D4 Classic need?
Each driver is rated 1000W RMS and 2000W peak. Plan an amplifier that delivers clean power near the RMS rating for the pair, and set gains carefully.
What size enclosure suits the SA-12 D4 Classic?
Sundown lists about 1.75 cubic feet ported per driver tuned near 35 Hz, or about 1.0 cubic foot sealed for a more compact box.
Can I wire the dual 4-ohm coils to my amplifier?
Each sub has two 4-ohm coils. Wire coils in parallel for 2 ohms per driver, or in series for 8 ohms, then combine the pair to match your amp.
Will it fit my car's box opening?
It needs a 12.625-inch cutout and 6.5 inches of mounting depth, with a 7.4-inch motor diameter. Measure your enclosure before building or buying.
Is this a pair or a single subwoofer?
This is a matched set of two 12-inch SA-12 D4 Classic subwoofers, so plan amplifier and enclosure capacity for both.
