Rockford Fosgate Punch PBR400X4D 4 Channel 400/4 Watts Amplifier

The Amp At A Glance:

• Flexible 4-channel power: Delivers 50 Watts x 4 at 4 Ohm, 100 Watts x 4 at 2 Ohm, or 200 Watts x 2 at 4 Ohm bridged.
• Efficient Class D operation: BRT (Boosted Rail Technology) produces full-range power with greater than 75 percent average efficiency.
• Useful tuning control: Selectable fixed 12 dB per octave Butterworth crossovers help tailor the amplifier to your speaker system.
• OEM system integration: Differential high-level inputs provide automatic turn-on, while the Remote-Out feature can activate other equipment when high-level inputs are used.
• Cleaner system setup: C.L.E.A.N. input and output clip detection uses indicator LEDs to help identify signal clipping.
• Compact installation: Its space-saving chassis supports discreet placement in trucks, subcompact, electric, and hybrid vehicles.
• Built-in protection: Real-time output and power-supply thermal sensing works with Rockford Fosgate proprietary protection.

The PBR400X4D gives a front/rear speaker system the power to sound fuller, clearer, and more controlled without demanding a large installation footprint. Its full-range Class D design can drive four channels or be bridged into two more powerful channels, giving you room to configure the system around your listening goals.

BRT efficiency helps deliver strong output while limiting demand on the vehicle’s electrical system. C.L.E.A.N. clip detection, selectable crossovers, and thermal sensing add practical control, helping you set up clean output and enjoy consistent sound across the full 20 Hz to 20 kHz frequency range.
