Value Engineered

Primus amplifier provides true Infinity performance at an affordable price while now lacking the features needed to properely tune and optimize performance.

Compact footprint

With it becoming more and more difficult to find spacious locations for amplifier mounting, Primus has been developed in a small compact form factor to allow more location versatility.

Full On-Board Protection.

Primus amplifier has on-board circuitry to protect them from shorts, temperature, overvoltage and undervoltage. An LED indicator is inlcuded on all four models to let you know when one of these conditions exists.


Infinity is one of the best selling car audio brands in the world. This is not a coincidence given the arduous testing and quality control. We take our craft seriously and want every consumer to have a world class experience that lasts and lasts.

Input Sensitivity

An input level control adjusts input sensitivity. When low level nputs are used, this control can adjust the input between 200mVrms and 5.0Vrms. When high level inputs are used, the control adjusts the input between 0.5Vrms and 15Vrms. This allows Primus amps to be conntected to virtually any factory system or serve as the foundation for a trophy winning aftermarket competition system.

Switchable bass EQ

This provides an available bass boost at 45Hz of 6dB or 12dB, serving as a great tool to optimize subwoofer and loudspeaker performance based on location and enclosure type.

Cool industrial design
