Product Overview
Add four-channel power without giving up much installation space with the Rockford Fosgate Punch PBR400X4d 4-channel amplifier. Its compact Class-D design delivers up to 400 watts total, with flexible output options for front and rear speakers or a bridged pair of channels.
Designed for compact installations, this amplifier also offers high-level auto turn-on and selectable crossovers. Element Ready™ amplifiers are designed for motorsports and motorcycle applications.
Key Features & Benefits
- Flexible four-channel output: Power front and rear speakers, or bridge two channels for a higher-output connection.
- Class-D design: Efficient full-range amplification suits installations where space is limited.
- OEM-friendly inputs: High-level inputs with auto turn-on support integration with factory-radio signals.
- Selectable crossovers: High-pass and low-pass settings help tailor the signal to your speaker setup.
- Monitoring and protection: C.L.E.A.N. clip detection, indicator LEDs, thermal sensing, and proprietary protection help monitor amplifier operation.
- Compact cooling design: The extruded aluminum heatsink uses convection cooling in a slim amplifier footprint.

Why Choose This Product?
The PBR400X4d gives you several ways to configure a compact multi-channel system. Its listed power ratings support four-channel operation at 4-Ohm or 2-Ohm, or a bridged two-channel setup at 4-Ohm.
Selectable crossover points provide another way to shape the signal for your system. Clip indicators and thermal sensing add useful monitoring features when the amplifier is working in a confined vehicle installation.
Installation & Compatibility Notes
Plan for the listed 1.53 x 4.25 x 6.75-inch dimensions, 8 AWG power/ground connection, and recommended 60 A fuse. Check your available mounting space and wiring requirements before installation.
For system planning, match the speaker connections to the amplifier’s listed impedance and power ratings. High-level inputs with auto turn-on are available for factory-radio integration. Front and rear speaker outputs use 4-pin harness connections.
