Power Acoustik BASS‑18C - Bass Restoration Processor


Take your car audio system to the next level with the Power Acoustik BASS-18C Bass Restoration Processor. Today’s compressed music files often lack the deep bass found in original recordings. The BASS-18C solves this by restoring those missing low-frequency harmonics, delivering fuller, richer sound that feels professionally tuned.


The onboard Bass Equalizer gives you full control of your system’s low end. Simply select the frequency to boost, then fine-tune the Q/width to increase harmonics around it — creating the exact bass response you want. Perfect for adding impact to subwoofers, the BASS-18C is commonly installed in-line before subwoofer amplifiers for maximum effect.


Convenience and control are at your fingertips with the dash-mount remote, which features variable subsonic filtering and bass level adjustment. Installation is flexible thanks to high-level speaker inputs and low-level RCA inputs, plus a 10V max RCA output to feed amplifiers. Added features like LED clipping indicators, load matching and ground isolation, and 12V turn-on output make the BASS-18C adaptable to a wide range of systems.


With high-fidelity specs including 0.03% THD, >105 dB S/N ratio, and 10 Hz – 22 kHz ±1 dB frequency response, this processor ensures clean, accurate sound. Compact at 7.5”L x 5.5”D x 1.25”H, the BASS-18C installs easily in almost any system while pulling just 300 mA of current. Unlock the hidden depth in your music and hear bass the way it was meant to be with the BASS-18C.
