The HOOL-X15.4DHE is a 15" car subwoofer from the DS18 HOOL-X series. It handles 4000 watts RMS and uses dual voice coils at 4 ohms per coil, so you can wire multiple subwoofers to the final impedance your amplifier is stable at. Peak power handling is 6000 watts. The high-excursion motor and suspension let the cone travel farther for deeper low-frequency output. Mounting requires a 14.1" cutout diameter and 11.19" of mounting depth, so confirm your enclosure before installing. Pair it with a matching monoblock amplifier and a properly tuned enclosure to get the most low-frequency output.

Rated at 4000 watts RMS and 6000 watts peak. Behind that rating: 4" voice coil on a black aluminum former wound with CCAW wire, a 500 oz ferrite motor and 59mm of one-way excursion. That is what lets a 15" cone move this much air without losing control.
Dual voice coils let you wire multiple subwoofers in series or parallel to reach the final impedance your amplifier is stable at, which gives you room to grow the system later.
The high-excursion motor and suspension allow the cone to travel farther than a conventional subwoofer, which moves more air and produces the low frequencies you feel rather than just hear. Give it a properly tuned sealed or ported enclosure to take advantage of it.
This 15" subwoofer requires a 14.1" cutout diameter and 11.19" of mounting depth. DS18 recommends a sealed enclosure of 1.25 cu ft and a ported enclosure of 2.5 cu ft tuned to 30Hz. Check these numbers against your enclosure before ordering: enclosure volume and tuning change the low-frequency response as much as the driver does.
A 88.3dB sensitivity rating turns amplifier watts into audible output efficiently, so you get more usable bass from the power you already have.
