Pioneer TS-WX400DA

With Class-D amplifier technology, the subwoofer generates 250W maximum power, consuming power at levels lower than conventional amplifier designs and reducing the need for a large, traditional heat sink. The result is a compact, easy to install amplifier which in some vehicles requires no direct battery connection.
