Audiopipe APHF-3000D-H2 3000 Watts Full Range Class D Mosfet Amplifier 2 Ohms

Full Bridge Monoblock Amplifiers

(49 products)

Our full-bridge monoblock amplifiers are for single-channel systems that need substantial power for a subwoofer or full-range speaker setup. Match the amp to the speaker load and the job, then plan the vehicle’s electrical system around its power demand. We focus on RMS output at the impedance you will actually wire.

Match RMS Power to the Speaker Load

Start with the speaker’s RMS rating and final wired impedance. A coil configuration or speaker connection changes the load the amplifier sees, so map the wiring before installation. Compare power figures at that specific load, not at a different impedance. The Audiopipe APHF-3000D-H2 is titled as a 3000-watt full-range Class D amp for 2 ohms. The Banda ELECTRA 3K 4-Ohm is rated at 3,000W RMS. The Stetsom BRAVO FULL 3K is also rated at 3000 watts RMS and described as full range. Confirm each model’s supported load and output rating in its manual.

Choose Full-Range or Bass-Focused Operation

Full-range monoblocks can serve a single channel beyond subwoofer duty when their frequency response and crossover controls suit the speaker. Bass-focused models are built around low-frequency playback. Set the high-pass or low-pass filter to protect the speaker and blend it with the rest of the system. The Sundown Audio SIA-3500D v2 is identified as a full-range mono amplifier. Check the frequency range and available filters for the exact model.

Plan Power, Wiring, and Mounting

Electrical support: High output draws substantial current. Plan charging-system capacity and battery support for the amplifier.
Power wire and fuse: Size wire for current and run length. Fuse the power cable near the battery, using the manufacturer’s specified fuse rating.
Speaker wiring: Treat both output terminals as live. Do not ground a speaker terminal or combine it with chassis ground.
Cooling and access: Mount securely with airflow and clearance around the amplifier. Follow its mounting and ventilation requirements.

Pair the amp with compatible car subwoofers, support the system with car batteries, and plan the run with car wiring and accessories. We recommend setting gains with a clean source signal and keeping speaker and power wiring routed separately where practical.
