Audiobank AP15 Digital Bass Processor & Crossover

The Audiobank AP15 is a 1/2 DIN digital bass processor and crossover that restores low-frequency detail, delivers up to 15V RMS input handling and 13.5V peak output while giving precise bass-level, frequency and subsonic control via a dash remote.

Adding a subwoofer is only part of the equation — the AP15 reconstructs the missing low-end information in compressed or poorly recorded tracks so bass hits feel fuller and more textured in your car. This compact half-DIN unit combines a bass maximizer, crossover, subsonic filtering and a lighted display with a dash-mount remote knob so you can dial in the exact amount of low end from the driver seat.

How does the AP15 restore low frequencies for better bass impact?

The AP15 uses a digital processing engine designed to detect and reconstruct lost low-frequency content, then blends it back into the signal path without overpowering the original track. That recreation provides punchier sub-bass and improved presence for tracks that sound thin from radio or streaming compression.

• Digital bass restoration algorithm recreates missing LF detail
• Efficient equalization circuit balances added bass with original signal
• Lighted display shows restoration activity for visual feedback

What controls let me tune bass to my car and music?

The unit gives you dedicated adjustments for frequency, width and level so you can match the bass boost to your subwoofer, enclosure and music style. A dash-mount remote knob provides convenient on-the-fly level control while the internal crossover and subsonic filter protect the subwoofer from unwanted frequencies.

• Frequency, width and level controls for tailored bass shaping
• Subsonic filter to remove ultra-low rumble and protect the sub
• Dash remote for instant, driver-side bass adjustment

What are the AP15’s technical capabilities and connections?

The AP15 supports robust head unit compatibility and amplifier chaining with an input specification suited to high-output systems and a peak output rating for driving downstream gear. It also features strong input noise rejection to keep unwanted hum and interference out of your low end.

• Input handling: rated to 15V RMS for high-level sources
• Output level: 13.5V peak for reliable drive to amplifiers
• Frequency response: approx. 10–10,000 Hz on output, 60dB input noise rejection

How does installation fit into a car audio system?

Designed as a 1/2 DIN chassis, the AP15 installs neatly into a standard dash opening or behind the dash and links to your head unit and amplifier with standard RCA and power wiring. The remote knob mounts to the dash for accessible control without needing to reach the main unit.

• Half-DIN footprint for tidy dash or behind-dash mounting
• Includes dash-mount remote for convenient level adjustment
• Standard wiring and robust input rejection simplify integration

Who this is for: The Audiobank AP15 is aimed at drivers who want fuller, more authoritative bass from existing car audio gear — especially owners of subwoofers, compact systems with compressed-source audio, and enthusiasts who need straightforward, tunable bass enhancement without swapping head units or amplifiers. It’s also a solid choice for installers seeking a compact electronic tool to optimize low-frequency performance in custom builds.
