Down4Sound D4S-AX5S – 5-Way Analog Active Crossover

The Down4Sound D4S-AX5S is a 5-Way Analog Active Crossover built for car audio enthusiasts who demand hands-on tuning power. Unlike DSPs that require apps or software, the AX5S gives you knob-based crossover control, making real-time adjustments quick and easy.

With dedicated subwoofer, front, and rear outputs, the AX5S offers full frequency management across your system. You get independent high-pass, low-pass, and band-pass filters, plus a subsonic filter, bass boost, and phase control, ensuring every driver in your setup is dialed in perfectly.

A wired bass remote is included, letting you control your sub output from the driver’s seat. With high-quality Tiffany RCA connections, silver-plated terminals, and a durable chassis, the D4S-AX5S delivers reliable old-school crossover control with modern build quality.

Perfect for bassheads, classic installers, and anyone who wants direct, analog crossover control without diving into software menus.
