P300-12T

The Rockford Fosgate P300-12T is a powerful 30 cm (12-inch) active subwoofer from the Punch series with a built-in 300-watt RMS Class-D amplifier. The compact, wedge-shaped enclosure was specifically designed for vehicles with limited space and is particularly well-suited for installation behind car seats or in shallow trunk areas.

The sealed MDF enclosure ensures precise and controlled bass reproduction. Thanks to the built-in amplifier, there is no need to install a separate power amplifier. The adjustable low-pass filter, bass boost, and phase control allow you to optimally tune the subwoofer to your existing sound system.

The high-level and RCA inputs allow for connection to both factory-installed and aftermarket radios. An automatic power-on function, convenient quick-connect terminals, and the included Punch Level Control bass remote provide added convenience during installation and operation.
