Choosing Between 12 Inch Subwoofers

A 12 moves noticeably more air than a 10 while still fitting a sealed or ported box in most sedans, coupes and many trucks. Single-sub systems are common, and a pair fits a lot of hatchbacks and SUVs. Decide first how much cargo space you can give up, since enclosure volume, not just cone size, sets how deep and loud the sub can play.

Power tiers

  • Daily systems: the Crossfire C3-V3 (400 watts RMS) and C5-V3 (600 watts RMS) work with modest monoblock amplifiers and a stock or lightly upgraded electrical system.
  • Sundown range: Sundown Audio makes up much of this collection, with the E-Series v.4 offered in D2 and D4, and the Crossfire XT3 and XT4 add more choices.
  • High output: the Crossfire C7-V3 (1600 watts RMS) and the 2000 watt Sparked Innovations SQL-2000 and Bass Blaster SQL call for serious amplifier power and electrical support.

Wiring the coils

D2 and D4 versions let you hit the load your amp wants. Two D4 12s with each sub's coils in parallel, then paralleled together, present 1 ohm; two D2 12s with coils in series and then paralleled present 2 ohms. Check that your amplifier is stable at the final load before you commit.

What to Pair With a 12

Use the box recommendation in each sub's manual, then choose from pre-built enclosures, which include single and dual 12 boxes. Size the amp to the combined RMS rating of your 12 inch subwoofers at the final impedance, and browse amplifiers for a monoblock that fits. Comparing sizes? See 10 inch models for a tighter fit or 15 inch models for deeper extension, or head back to all car subwoofers.
