Rockford Fosgate P300-10T 10" 300-Watt Powered Truck Subwoofer Enclosure

Overview

Right in the middle of the lineup—this is the sweet spot.

The P300-10T gives you more output than the 8", but without taking up the space of the 12". It’s a 10" powered subwoofer built into a slim, truck-style enclosure designed for behind-seat installs.

This is what most truck owners actually need.

What It Is

A complete bass system in one box.

• 10" high-output subwoofer
• Built-in 300W Class-D amplifier
• Slim wedge enclosure for trucks

No separate amp, no guesswork—just add power and signal.

Why It Works

Everything is matched from the factory.

• “Closed-loop” design for balanced output
• Clean, tight bass (not sloppy)
• Enough output to actually notice—without overpowering the system

The enclosure, amp, and sub are all designed to work together, which is why it performs better than most pieced-together budget setups.

Performance

• 300 Watts RMS power
• Tuned for real-world listening
• Strong mid-bass with usable low-end

It’s not a competition setup—but it’s a solid upgrade over factory systems and small powered subs.

Installation

Built for quick installs.

• Works with factory or aftermarket radios
• High-level (speaker wire) inputs
• Low-level (RCA) inputs
• Auto turn-on (no remote wire needed in most installs)
• Quick disconnect power and signal plugs

Easy in. Easy out.

Tuning & Control

Simple but effective.

• Variable low-pass crossover
• Bass boost (0 to +12dB)
• Phase switch (0° / 180°)
• Included remote bass knob

Dial it in from the driver’s seat.

Truck-Friendly Design

Where this shines:

• Slim wedge enclosure fits behind seats
• Designed specifically for truck cabins
• MDF construction with durable finish

Built to fit where space is tight.
