Authorized dealer · Car Audio Bargain
Car subwoofers in every common size, from compact 6.5 inch drivers for tight spaces to 18 inch woofers built for wall-shaking bass. Car Audio Bargain is an authorized dealer for Sundown Audio, Crossfire Car Audio and Sparked Innovations, with dual voice coil options from D1 to D4.
Shop entry-level picks like the Crossfire C3 Series up to competition-grade builds, then filter by size, impedance and brand to find the right match.
Start with the space you have and the sound you want. Smaller drivers react quickly and fit under seats or in shallow boxes, while larger cones move more air and dig deeper. A 12 inch subwoofer is where many first systems land because it balances output, box size and power demands. Go down to 8 or 10 inches for tight trunks and punchy kick, or up to 15 and 18 inches for SUVs, hatchbacks and wall builds with room for a big enclosure.
Most subs here are dual voice coil (DVC) designs listed as D1, D2 or D4, meaning two coils of 1, 2 or 4 ohms each. Wiring the coils in series adds their impedance and wiring them in parallel divides it, so a single D4 sub can present 8 or 2 ohms and a D2 can present 4 or 1 ohm. Choose the coil option that lands your final load on an impedance your amplifier is stable at.
Match continuous (RMS) power, not peak numbers. An amp that delivers roughly the subwoofer's rated RMS at your final load gives clean output with headroom. Underpowering a sub and then turning the gain up to compensate causes clipping, a common way voice coils get damaged.
Crossfire Car Audio covers daily-driver budgets with its C3, C5 and C7 Series, whose V3 versions are rated at 400, 600 and 1600 watts RMS respectively, plus the XT line. Sundown Audio spans the SA, U, X, Z, E and M Series for everything from clean daily systems to high-output competition setups. Sparked Innovations offers the SQL-2000 and Bass Blaster SQL in 10 to 18 inch sizes for builders chasing a blend of sound quality and loudness. Want a proven driver for less? Refurbished Sundown Audio subs carry a 90-day warranty.
A subwoofer is only as good as its box. Sealed enclosures give tight, controlled bass in less space, while ported designs trade a larger footprint for more output around the tuning frequency; always follow the manufacturer's recommended internal volume. Browse pre-built enclosures, then pair your car subwoofers with a monoblock from our amplifiers and a correctly sized amp wiring kit so the power wire, fusing and ground can handle the current draw. If a driver ever blows, factory recone kits can put it back in service rather than replacing it outright.
