Description

The Infinity Primus 3000A is a mono subwoofer amplifier engineered to deliver robust low-frequency sound. It offers 300 watts RMS x 1 at 2 ohms, with a total peak power of 600 watts. Key features include a variable low-pass filter that can be adjusted between 32-320 Hz with a 12 dB/octave slope, allowing precise control over your subwoofer's frequency range. A variable bass boost is also available, ranging from 0-12 dB at 40-100 Hz, to further enhance the low-end response. Additionally, a phase adjustment control from 0-180° lets you fine-tune the subwoofer's output to match the rest of your system. The Primus 3000A is equipped with both preamp and speaker-level inputs, offering flexibility in how you connect it to your head unit. It includes two 15A fuses and comes with a 12-inch speaker-level input harness. Wiring and hardware are not included with the amplifier.
