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.
Reliability
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 crat 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 6.0Vrms. 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
Black with grooved center panel, polished badge, black painted end panels and bottom.

Features:
- Power Output: The Infinity Primus 3000a monoblock amplifier delivers 300 watts RMS to a 2-ohm load, and 600 watts total peak power. No 4-ohm power spec is provided.
- Protection Circuitry: The amplifier features protection circuitry for thermal overload, DC voltage on the audio output, over- or under-voltage (<9V or >16V), and short circuits. The LED on the end of the amp glows red if the amp goes into protection mode.
- Gain: The Primus 3000a's rotary gain control let you match the amp's input sensitivity to the output of the source unit. The input sensitivity range of the amplifier 0.2V - 5V for a line-level input, and 0.5V - 12V for speaker-level input. A small screwdriver (not included) is required to set the gain.
- Crossover: The amp features a low-pass filter that is non-defeatable. It eliminates a range of high frequencies that are sent to the subwoofer. You can adjust the cutoff frequency of the low-pass filter from 32Hz to 320Hz using the rotary control. A small screwdriver is required to adjust the frequency.
- Phase: The Primus 3000a features a continuously variable phase control, adjustable from 0° to 180°. While playing bass-heavy music, you should turn the phase control until you find the setting that provides the most bass. If you don't detect any real difference, leave the setting at 0°.
- Bass EQ: The amplifier's Bass EQ circuit lets you increase the bass output from 0dB to 12dB. You can also choose the center frequency of the bass boost. This setting is continuously variable from 40Hz to 100Hz.
- Terminals: The Infinity Primus 3000a uses screw terminals for the +12V power, ground, turn-on (remote) lead, and speaker outputs. The screws can be tightened/loosened with a Phillips-head or flat-head screwdriver (not provided).
- Power/Ground: The +12V Power and Ground terminals will accept up to 4-gauge wire. It is recommended that you use a minimum of 8 AWG power wire to the battery, with an in-line 30A fuse installed no more than 18" from the battery terminal. An 8 AWG ground wire (minimum) is also recommended, and attached to a metal area close to the amplifier.
- Remote Turn-On: The Remote screw terminal will accept up to 8 AWG wire. Typically, an 18 AWG turn-on lead is included in an amplifier wiring kit.
- Speaker-Level Input: The amp includes a 12" speaker-level input harness for connecting the amp to a factory radio or aftermarket head unit. You should splice left and right speaker wires from the head unit to the harness and plug the harness into the amp.
- Line-Level Inputs: The amplifier is equipped with one pair of RCA inputs for connecting stereo RCA patch cables from the head unit to the amp. If your source unit only has one subwoofer output, you can connect it to either the left or right RCA inputs on the amp.
- Speaker Outputs: The amp features screw terminals for connecting one speaker. The amplifier's minimum speaker impedance is 2 ohms, so you can connect any combination of speakers that presents a 2 ohm load or higher.
