Kicker 51CWQ154 COMP Q 15" 1200 Watt Car Audio Subwoofer DVC 4 Ohm Sub CWQ154

The CompQ 15-inch subwoofer in dual 4-ohm form is the top of the round CompQ line, built close to the square L7 in construction and performance. The 4-ohm coil pair gives you 2 ohms wired in parallel or 8 ohms in series, and two of them cover the 1-ohm and 4-ohm loads most mono amplifiers are rated for.

Ribbed Santoprene surrounds and a BlueLace large-diameter progressive roll spider keep the suspension linear from quiet passages to full excursion, so the cone stays controlled as power increases. Recommended amplifier power is 600 to 1,200 W RMS and sensitivity measures 88 dB, which is high for a driver of this size and means the sub gets loud without demanding every watt available.

Frequency response reaches 18 Hz, low enough to reproduce content most systems never touch. In a vehicle cabin those frequencies register physically, which is exactly the point of a 15.

Enclosure planning: sealed volumes of 1.5 to 6.0 cu ft, vented volumes of 3.0 to 6.0 cu ft, with panel dimensions published for a minimum 1.5 cu ft sealed box. Mounting depth is 8-15/16 inches with a 13-7/8 inch cutout, so budget trunk, cargo, or truck bed space for the build.
