Which is better for a daily driver?

The Kicker CompR 12. At 500W RMS and 86.9 dB sensitivity it plays loud on a normal mono amp and fits a 5-3/4 in deep box. The Sundown needs a 1500W-class amp and an 8.4 in deep enclosure to show its advantage.

Is the Sundown worth the extra money?

Only if you are building for high output. At $429.99 at Amazon as of November 3, 2026, it costs about $278 more than the Kicker at $151.96 at Crutchfield. That buys 1500W RMS handling, but you also pay for a bigger amp, box and wiring.

The Sundown can be louder, but only with the power to feed it. Its 1500W RMS rating and 3000W peak beat the Kicker's 500W RMS and 1000W peak. On the same modest amp, the Kicker's higher 86.9 dB sensitivity means it plays louder.

Which needs a bigger enclosure?

The Sundown. Its 8.4 in mounting depth requires a deeper custom box than the Kicker's 5-3/4 in. The Kicker works in sealed or ported boxes and fits more vehicles without a custom build.

Do both wire the same way?

Yes. Both are dual 4-ohm subwoofers, so each wires to 2 ohms or 8 ohms. Match the final impedance to what your amplifier is stable at.

The Kicker is the safer bet for long daily use at moderate power. Its Forced Air Cooling and SoloKon brace target heat and distortion at 500W. The Sundown is built for high power, but it lives longer only with a correct box and clean power.

Kicker CompR 12" Dual 4-Ohm Subwoofer vs Sundown Audio SA-12 v.3 D4 12"

For most shoppers, the Kicker CompR 12 is the better buy. It costs $151.96 at Crutchfield as of November 3, 2026, versus $429.99 at Amazon for the Sundown SA-12 v.3 D4. The Sundown handles far more power (1500W RMS vs 500W) and suits high-output builds, but it needs a bigger box, a stronger amp and more electrical support.

Today the Kicker CompR 12" Dual 4-Ohm Subwoofer costs $278.03 less at its best price.
