OD1-7500D | 7500W Class D Monoblock Amplifier

Power Acoustik OD1‑7500D Overdrive Series 7500W Class D Monoblock Amplifier

The Power Acoustik OD1‑7500D delivers serious output for subwoofer systems without eating up valuable installation space. As part of the Overdrive Series, this Class D monoblock amplifier is designed for modern builds where compact size and thermal stability matter just as much as raw power.

Built to push boundaries without breaking the bank, the OD1‑7500D outputs up to 7,500 watts peak and a steady 3,000 watts RMS at 1 ohm, all while maintaining a compact form factor that fits in tight install zones. Whether you're running a single low-resistance sub or stacking a multi-amp setup, the 1-ohm stable monoblock design is ready to meet high-output demands.

Built to Drive: Class D Power Meets Durability

Engineered with a PWM MOSFET power supply and military-grade PCB construction, this amp holds its own against extreme thermal conditions and current loads. It includes built-in thermal, short circuit, and overload protection, providing peace of mind when pushing bass-heavy setups to their limit.

This isn’t just about power—it’s about control. The OD1‑7500D includes variable low-pass crossover (40–180Hz), subsonic filter (10–50Hz), and a precise 12dB bass boost for tuning your low-end response to match enclosure specs and listening preferences. The included remote bass knob lets you dial in levels from the driver’s seat without pulling the rack.

Installation-Ready and Stackable

With a footprint of just 14.75" x 7.25" x 2.3", the OD1‑7500D is built for stealth installations. It supports both high-level speaker input and RCA line-level input, making it compatible with factory head units and aftermarket systems alike. Use it standalone, or bridge with another OD1-series amp to double the output for larger setups.
