Rockford Fosgate Punch P300-12T 12" 300-Watt Powered Truck Enclosure

The Rockford Fosgate Punch P300-12T is a self-contained 12" powered truck subwoofer enclosure with a built-in 300-watt Class-D amplifier, delivering tight, low-end bass in a compact, truck-ready package. This all-in-one solution targets enthusiasts who want a straightforward upgrade that adds substantial low-end punch without external amps or extra wiring.

• On-Board 300 Watt Class-D Amplifier: An integrated amp with a closed-loop design drives the 12" woofer directly, delivering efficient, controllable bass without a separate amplifier.
• 12" Low Impedance Woofer: A single woofer optimized for the internal amp ensures strong low-end output as the system demands change.
• Low Pass Crossover (50 Hz–200 Hz), 12 dB/Octave: Shapes the bass range to mate with other speakers for a coherent kick in the cabin.
• Bass EQ (0 dB–+12 dB): Allows adding low-end punch to suit vehicle acoustics and personal taste without repositioning the enclosure.
• Phase Control (0°–180°): Fine-tunes woofer phase for better bass integration with the rest of the system.
• Remote Bass Level Control Included: Lets you dial in bass output from the driver's seat for in-vehicle listening adjustments.
• Intelligent Auto Turn-On/Off: Eliminates the need for a separate turn-on wire by auto-detecting audio signal reception.
• Inputs: Low-Level RCA and High-Level (Speaker Level): Connect to factory head units via speaker-level inputs or aftermarket systems via RCA inputs; RCA pair is L/R summed when used.
• Input Impedance and Sensitivity: 20 kΩ input impedance; Low-Level 150 mV–6 V; High-Level 300 mV–12 V for flexible integration with diverse head units.
• Power and Ground Connections: Robust power/ground wiring with 8 AWG B+/GND and 18 AWG REM conductors for a solid install.
• Enclosure and Finish: 5/8" MDF sealed enclosure with a heat-activated vinyl finish for durability and predictable acoustics.

In a typical truck build, the P300-12T provides a compact, self-contained bass upgrade that connects to factory or aftermarket head units via either high-level or RCA inputs. The auto turn-on feature, remote bass control, and adjustable crossover/bass EQ enable precise tuning for the vehicle’s acoustics, while the sealed enclosure and Class‑D efficiency deliver tight, repeatable bass without requiring extra amplification or a ported enclosure.
