Description
Product Overview
Get a two-channel system into a tight space with the Rockford Fosgate Punch PBR300X2 amplifier. Its compact chassis and Boosted Rail Technology (BRT) deliver rated power without a traditional switching power supply, while high-level inputs and DC offset turn-on support OEM integration.
Use it to power a compact front stage or configure it for a bridged subwoofer setup. The built-in high-pass and low-pass filters give you control over the frequency range sent to your speakers.
Key Features & Benefits
- Compact chassis: The small footprint helps with installation where dash, under-seat, or trunk space is limited.
- Boosted Rail Technology: The non-switching design is specified to reduce heat while maintaining rated output.
- OEM integration: High-level inputs and variable DC offset turn-on allow connection with factory radios.
- Flexible output: Two-channel and bridged power ratings support different system configurations.
- Adjustable crossover: High-pass and low-pass controls help shape the signal for the connected system.
- CTA-2006 compliant: The amplifier also includes a 1-year warranty.

Why Choose This Product?
The PBR300X2 is built for installations where space is at a premium but a dedicated amplifier is still needed. Its BRT design avoids a traditional switching power supply, and the compact chassis makes it easier to plan around confined mounting areas.
Choose the appropriate rated power for your speaker load and configuration. The amplifier offers two-channel ratings at 4-Ohm and 2-Ohm, plus a bridged 4-Ohm rating for a different setup.
Installation & Compatibility Notes
Plan for the amplifier’s 1.53" H x 4.25" W x 6.75" D chassis, 9–16 VDC operating range, and specified power and speaker wiring. Its 4-pin high-level input harness and variable DC offset turn-on are intended to simplify integration with factory radios.
The recommended 50 A fuse is not included. The product description identifies Element Ready™ amplifiers as designed specifically for Motorsports and Motorcycle applications; it does not identify this model as Element Ready.
Frequently Asked Questions
What power does the PBR300X2 provide?
Rated output is 100W x 2 at 4-Ohm, 150W x 2 at 2-Ohm, or 300W x 1 at 4-Ohm bridged. Dynamic power ratings are listed separately in the specifications.
Can I connect it to a factory radio?
It has high-level inputs through a 4-pin harness and variable DC offset turn-on for OEM integration.
Does it have adjustable filters?
Yes. High-pass and low-pass controls each range from 50Hz–500Hz at 12dB/Oct. An all-pass option is also listed.
What fuse should I plan for?
The recommended fuse is 50 A, and the fuse is not included.
