What size subwoofer should I get for my car?

It depends on your vehicle's available space and your sound goals. Sedans typically fit 10–12 inch subs, SUVs and trucks can accommodate 12–15 inch subs, and hatchbacks work best with 8–10 inch shallow-mount subs. Use the Subwoofer Finder to get a recommendation based on your specific vehicle type.

How many subwoofers do I need?

Most daily drivers sound great with one or two subwoofers. A single sub is enough for clean bass reinforcement. Two subs give more even bass distribution in the cabin and more total output. Competition SPL builds may use three or four.

What is the difference between a ported and sealed subwoofer enclosure?

Sealed enclosures produce tighter, more accurate bass — ideal for music with fast transients like rock and jazz. Ported enclosures are louder and more efficient, emphasizing deep bass — great for hip-hop, EDM, and SPL builds. Your subwoofer's recommended enclosure type depends on its design parameters.

What does RMS power mean for a subwoofer?

RMS (Root Mean Square) is the continuous power rating — the wattage your subwoofer can handle all day without damage. Peak or max wattage refers to brief bursts. Always match your amplifier to the RMS rating, not the peak rating.
