JL Audio ACS112LG-TW1 PowerWedge+ Sealed Single Amplified Subwoofer Enclosure 0.25Ω
In PowerWedge+™ systems, the power is built right into the subwoofer system. Housing a proprietary Class D amplifier, this subwoofer system employs JL Audio's exclusive DCD™ amplifier technology to extract maximum output from its specially engineered, ultra low-impedance TW1 driver. By combining direct power conversion with an ultra-high current output section, DCD™ amplifiers are free of conventional switching power supplies, enabling them to generate remarkable power with unprecedented efficiency.
Harnessing the performance and insanely small box requirements of the TW1 subwoofer driver, this subwoofer system is designed to deliver amazing sub-bass from an enclosure that is only 6.625 in. (168 mm) deep. Its low-profile enclosure design has been carefully engineered to the optimum sealed enclosure alignment for the 12TW1 driver and has been fine-tuned through extensive real-world listening.
Integration to OEM and aftermarket head units is a snap thanks to a variety of input options and automatic turn-on capability (via signal sensing or DC offset sensing). Also included is a variable frequency low-pass filter (50-200 Hz), along with output polarity control switch. Adding an optional RBC-1 remote level control (sold separately) lets you control subwoofer levels directly from the driver’s seat. A quick-disconnect power connector makes it easy to remove the subwoofer when you need the extra space.
Note: DCD™ amplified systems use very specific components. Never use a DCD™ amplifier or its companion subwoofer(s) with incompatible, non-DCD™ products. Doing so will void the warranty and may cause severe damage.

I would highly recommend this amp if you want a simple and clean setup that doesn't take up too much space. I have had mine for 5 Plus years and the Driver has recently gone out on me but i can not complain. The one problem you encounter when the driver gives out on you is replacement, it is very hard to find a replacement driver instead of buying a completely new box.
