The HOOL-X15.4DSPL 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. It is built for SPL competition, where maximum output is the goal. The cone is fiber glass. Mounting requires a 14.0" cutout diameter and 11.18" 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 and a 500 oz ferrite motor. 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.
This subwoofer is built for SPL competition, where maximum measured output is the goal. Plan for a high-current electrical system and an amplifier that can deliver the full RMS rating.
This 15" subwoofer requires a 14.0" cutout diameter and 11.18" of mounting depth. Check these numbers against your enclosure before ordering: enclosure volume and tuning change the low-frequency response as much as the driver does.
The fiber glass cone stays rigid at high excursion while resisting fatigue over time, so the driver keeps its shape and output under sustained high power.
