Kicker CompRT 12″ Slim Subwoofer (500W RMS Dual 2 Ohm)

The Kicker CompRT 12″ Slim Subwoofer is designed for drivers who want serious bass performance without sacrificing valuable installation space. Featuring an ultra-shallow mounting depth of less than 4 inches, the CompRT is perfect for under-seat enclosures, behind-seat installations, custom stealth builds, and compact vehicle audio systems.

Despite its slim profile, the CompRT delivers impressive low-frequency output thanks to its advanced motor structure, high-power handling, and innovative Kicker engineering. Capable of handling 500 watts RMS and 1000 watts peak power, this subwoofer produces deep, impactful bass while fitting where traditional subwoofers simply cannot.

The CompRT features Kicker's exclusive SoloKon™ technology, which integrates the cone and vented back brace into a single structure for increased strength, reduced distortion, and improved cooling. Combined with a thick magnet assembly and UniPlate™ back plate design, the subwoofer delivers excellent thermal management and long-term reliability.

Designed for both on-road and off-road use, the CompRT also features a UV-resistant cone and surround, making it suitable for harsh environments where durability is essential. Forced-Air Cooling™ technology helps reduce operating temperatures, allowing the subwoofer to run cooler and maintain consistent performance during extended listening sessions.
