With ±18dB of EQ control across five critical bands, you can easily enhance or tame bass, mids, and highs to your liking. The digital bass processor restores low frequencies often stripped out by compressed audio or factory head units, while the subsonic filter (35–80Hz) protects your subs from unwanted rumble. The MPQ-6BX features three versatile inputs (AUX, Low-Level RCA, and High-Level speaker input), making it compatible with almost any source. On the output side, it boasts six preamp outputs (front/rear/sub) with a powerful 7V RMS output, ensuring clean signal delivery to your amplifiers. With 0.01% total harmonic distortion, 110dB SNR, and 150Ω output impedance, this equalizer delivers pristine audio performance across the full 20Hz–20kHz frequency range. Its compact size and PWM switching power supply make it efficient and easy to install in tight dash spaces.
