Kicker TRTP8 8 Inch CompRT Down-Firing Subwoofer Enclosure with Passive Radiator 600W Peak 2-Ohm
The Kicker TRTP8 8-inch down-firing loaded enclosure is the ultimate solution for audiophiles seeking big bass in the smallest possible footprint. Standing at an incredibly slim 5-3/8 inches tall, this enclosure is designed to disappear under truck seats or tuck away into the tightest trunk corners without sacrificing valuable cargo space. Its specialized down-firing design allows you to stack cargo directly on top of the enclosure, using the vehicle floor to reinforce the bass output for a deep, rich sound that defies the system's compact dimensions.
Precision-engineered for performance, the TRTP8 features a high-output 8-inch CompRT active subwoofer paired with a reFLEX passive radiator. This unique combination allows the enclosure to move a significant volume of air, delivering low-end extension typically found in much larger boxes. Built with heavy-duty MDF and extensive internal bracing, the TRTP8 is rated for 300 Watts RMS and features Kicker's Forced-Air Cooling technology to keep the motor running 20% cooler for maximum reliability during long-term use.
