The built-in amplifier delivers 4 x 50 Watts for the speaker channels and 240 Watts for the built-in subwoofer (peak power).
Compact installation
The very compact measurement of only 350mm length x 245mm width x 80mm height allows the PWD-X5 to be installed under the front seats of many vehicles. It can be also easily installed in the trunk of hatchback or coupe cars. The total weight of the product is just above 5kg.
Extensive sound tuning functions
Use the built-in 10-band Parametric EQ, digital time correction and digital crossover to tune the sound of your vehicle. You can do the main setup by connecting a PC using the free Alpine software or via the included wired controller. There is also a smartphone app that allows users to switch between pre-sets on the go and adjust subwoofer and volume levels.
Wide connectivity options
You can connect the PWD-X5 to an Aftermarket radio using RCA inputs. If you have an original radio in your car that has nor RCA connections, you can connect it to the DSP amplifier using the high-power inputs. There are also 2 USB ports used for the included external Bluetooth dongle and to connect the wired remote control and PC for setup.
Wired Remote Control
The remote control unit is connected with the DSP amplifier by USB. Use the rotary encoder to select pre-sets, input sources, sound settings and more.

E&OE
The HX subwoofers were designed to reproduce the very lowest octaves of the audio spectrum with precision, impact and power. Groundbreaking technologies in every detail: V-cone, forced ventilation system, low-resonance basket and ultra-efficient motor assembly. The Hi-Energy subwoofer range features dual coil models to increase the flexibility of your subwoofer system design. This will allow you to manage the different connectivity solutions and the number of subwoofers in a particular design in order to make the most of the amplifier power delivery characteristics. Dual voice coil, i.e.: double the power, double the efficiency, with even smaller boxes. The best solution to all your needs; low frequency output and control that will meet your most enthusiastic expectations.

The Hertz Energy.5 ES 250.5 car audio subwoofers offers a dynamic bass and are capable of outstanding SPL never achieved in this category of the market.
The introduction of the V-cone® technology had a big impact in the efficiency of the ES.5 subwoofers, also improving cone stiffness and reducing the weight of the moving assembly, allowing a higher strength voice coil for a higher peak power handling.

The Hertz Energy.5 ES 250D.5 subwoofers offer a dynamic bass and are capable of outstanding SPL never achieved in this category of the market.
The introduction of the V-cone® technology had a big impact in the efficiency of the ES.5 subwoofers, also improving cone stiffness and reducing the weight of the moving assembly, allowing a higher strength voice coil for a higher peak power handling.
The implementation of the surround and spider geometry, as well as the selection of the materials used, contributed to achieving unmatched mechanical and thus acoustical linearity.
This, combined with a drastic reduction of the Vas, provides the ability to achieve high undistorted SPL output in even small enclosures.
The Hertz Energy.5 subwoofers are the perfect choice for solid, powerful bass in perfect harmony with improved vehicle integration.
