JL Audio ACP208LG-W3 V3

The ACP208LG-W3 V3 is an 8" (20cm) active enclosure subwoofer from JL Audio. This MicroSub bass reflex system is equipped with two 8W3 v3-4 subwoofers and an integrated Class-D DCD™ amplifier. The system features a built-in 500W Class D amplifier and a black carpet bass reflex cabinet. It also uses JL's exclusive DCD™ amplifier technology to get the maximum performance from its specially developed, ultra-low impedanceW3 v3 driver. It impresses with its excellent performance and unparalleled efficiency. A highlight is the easy integration into OEM and aftermarket head units thanks to a variety of input options and the automatic switch-on function.

• Amplified subwoofer system with  two 8W3 v3-0.4 subwoofers, built-in 500W Class D amplifier, black carpet - bass reflex cabinet
• With MicroSub+™ systems, the power is integrated directly into the subwoofer system. This incredible subwoofer system with a proprietary Class-D amplifier uses JL's exclusive DCD™ amplifier technology to get the maximum performance from its specially developed, ultra-low impedanceW3 v3 drivers. By combining direct power conversion with an ultra-high current output section, DCD™ Amplifiers free from conventional switching power supplies, allowing them to produce remarkable power with unprecedented efficiency.
• The key to the bass reflex enclosure's performance is its efficient slot port design and the precise tuning of its 8Wv3 subwoofer. Extensive internal bracing allows the use of thinner wall material, maximizing the enclosure's internal volume relative to its external volume. The port is wrapped around two enclosure walls to produce the required low tuning frequency, providing excellent extension and smooth response. The port's tapered inlet and outlet further improves sound quality by minimizing the noise of airflow through the port.
• Integration into OEM and aftermarket head units is a breeze thanks to a variety of input options and automatic power-on functionality (via signal sensing or DC offset sensing).
• Also included is a low-pass filter with variable frequency (50-200 Hz) and a switch to control the output polarity.
• By adding an optional RBC-1 remote control (sold separately) you can  control the subwoofer level 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 the associated subwoofer(s) with incompatible, non-DCD™ products. Otherwise the warranty will be void and serious damage may occur.
