Bring Out the Beast in Your Factory Audio
Who says stock sound systems have to stay boring? The Nemesis Audio NA-LOC4 lets you unleash serious volume and clarity without replacing your factory head unit. With four channels of high-level inputs handling up to 40 volts, it converts speaker signals into strong RCA outputs, pumping out up to 9.5 volts for clean, distortion-free power. Whether you're driving door speakers or subwoofers, this converter makes sure your amps get the full signal they deserve, all while keeping your factory setup intact.

Smart Features That Know What You Want
This little box is smarter than it looks. It turns on automatically using DC offset or audio signal detection, so it powers up right when your music starts. The input load switch helps avoid factory shut-off issues, while the adjustable bass boost adds up to 12 decibels of punch right where it counts. Want to tweak it from the driver's seat? Use the included remote bass controller. From the LED clip indicator to the selectable ground isolation, every feature is built to keep your sound clean, powerful, and completely under your control.
