KICKER 48CWRT674 CompRT 300w Shallow 6.75" Subwoofer DVC 4-ohm Car Sub CompRT67

The KICKER CompRT 6-3/4-inch subwoofer is a shallow-mount sub for vehicles where depth is the limiting factor. At 2-3/4 in of mounting depth, it fits under a seat, behind a back bench, or in a factory sub location that a standard woofer will never clear. Dual 4-ohm voice coils give you wiring options and handle 150W RMS, with 300W peak power and 82.6 dB sensitivity at 1W/1m.

Signature red double stitching bonds the Santoprene surround to the polypropylene cone so the joint survives full excursion in a shallow frame. SoloKon technology joins the cone to a vented back brace, creating one integrated unit that cools the motor and holds distortion down. An advanced suspension and heat management system keeps the bass deep and consistent as output climbs. Forced-Air Cooling runs the sub about 20 percent cooler than the previous generation.

The CompRT 6-3/4 works best in a sealed enclosure between 0.18 and 0.75 cu ft, which is a realistic box size for a truck cab, an SUV cargo floor, or a spare-tire well. The cutout is 5-5/8 in, so the footprint stays reasonable even where the depth is not.

Pair it with an amplifier rated near 150W RMS and you get low end that sounds like a full-size sub from a space most people write off as unusable.
