About the AudioControl Epicenter Micro
From our tech experts at CEN
The AudioControl Epicenter Micro is a compact digital bass restoration processor and line output converter. It accepts speaker-level inputs up to 40 Vrms (400W) and line-level inputs, delivering up to 9.5 Vrms on two RCA outputs. The included ACR-4 dual-knob remote provides independent dash-mounted control of bass restoration and output level.
Who it suits
The Epicenter Micro suits anyone adding an amplifier or subwoofer to a factory head unit that lacks RCA outputs. It also works well where bass restoration is needed alongside OEM integration. For a six-channel solution, see the AudioControl LC7i.
Our tech experts advise
Selectable input impedance (20Ω, 60Ω, 20kΩ) allows accurate signal matching to most factory speaker wiring. Three trigger options — 12V remote, GTO Signal Sense and Audio Sense — mean it works even without a dedicated remote wire. The subsonic filter can be bypassed if your amplifier handles its own filtering. Fitting is priced per vehicle; visit our Nottingham car audio installation page to discuss your setup.
