In a typical four‑channel install, MFA-4.120 provides four outputs for separate channels, with the option to bridge two channels for higher power into a single load. The wide frequency range, 12 dB/Oct crossovers, and the ability to run LPF and HPF simultaneously give you precise tonal shaping across the system, while the 0.4–8 V input sensitivity ensures compatibility with a range of source units. Built for vehicle use with a 9–15 V operating range and 4 Ga input / 10 Ga output wiring, it integrates into compact, high‑power builds without sacrificing signal integrity, supported by a 90 dB SNR.
