KICKER 48TRTP122 TRTP 12" 1000w Down Firing Subwoofer Enclosure+Passive Radiator

The 48TRTP122 is a thin-profile loaded enclosure that puts 12-inch bass where a standard box will not fit. The cabinet stands 6-1/8 inches tall and fires downward, so it slides under most full-size truck seats or lies flat in a trunk while leaving the space above it usable. Inside are two 12-inch cones: an active CompRT subwoofer and a reFLEX passive radiator that pushes output lower without the port noise or extra volume a vented box would need. Both are pre-wired to a single 2-ohm terminal, so a monoblock amplifier hooks up in minutes. The box handles 500 watts RMS and 1000 W peak, and 98 dB sensitivity means it plays loud on modest power. Construction is thick MDF with extensive internal bracing, so the top panel takes stacked toolboxes, gear bags and groceries without flexing. The CompRT sub bonds a Santoprene surround to a polypropylene cone with signature red double stitching, while SoloKon technology ties the cone to a vented back brace to cut distortion and shed heat. Forced-Air Cooling runs the motor about 20 percent cooler for long listening at volume. It suits crew-cab trucks, hatchbacks and any build where cargo room counts as much as output.
