KICKER 48TRTP82 TRTP 8-Inch Thin Down-Firing Subwoofer + Passive Radiator Enclosure, 2-Ohm

Ultra-Compact, High-Impact Bass

Meet the KICKER 48TRTP82 TRTP enclosure, engineered to disappear into your vehicle while delivering meaningful low-end presence. The eight-inch driver array is tucked away behind a slim profile, so the system blends with your interior rather than dominating it. The result is a clean, integrated look with room for cargo and everyday gear.

Smart Cooling for Reliable Performance

New CompRT technology uses forced-air cooling to keep critical parts cooler under heavy use. In real-world terms, this can help maintain consistent output during long drives or spirited listening sessions, reducing heat buildup in tight spaces where airflow matters.

• Forces air over the voice coil to help manage heat
• Potentially longer playback without heat-induced sag
• Designed to work with typical aftermarket amplifiers for low-impedance loads

The enclosure also benefits from internal bracing, reinforcing the structure to resist flex and vibration. This helps preserve clarity as you push the volume while driving, making bass feel tight and controlled rather than rattling in the trunk.

Punchy Bass in a Tight Package

The internal design centers a high-output ReFLEX passive woofer, which translates into louder bottom-end response without requiring a large box. The 8-inch down-firing configuration is optimized for space, directing bass toward the cabin for a more engaging listening experience in daily commutes, road trips, or weekend getaways.

• Down-firing orientation helps bass travel into the cabin
• Low-profile footprint keeps your trunk usable for groceries or gear
• 2-ohm impedance pairs well with common car audio amplifiers

Whether you’re upgrading a compact sedan, a hatchback, or a small SUV, this enclosure is designed to fit without forcing a retrofit. If you value a discreet install that still delivers audible impact, the 48TRTP82 offers a practical balance of performance and fit.
