ZEN POWER-9 (A2B-PLUS)

YOUR FORD + GM A2B AUDIO UPGRADE SOLUTION

The ZEN-POWER9 is an all-in-one plug-and-play* replacement amplifier for pre-2025 Ford and 2024+ GM vehicles with A2B networks (use the QR code to confirm applications). The ZEN-POWER9 delivers a fully-digital signal path, pristine sound quality, and advanced control of your systems’ sound.

Each of the nine channels of amplification is proportioned for your needs, while the 14-channel DSP also manages any optional mono amplifier added to the system.

The ZEN-POWER9 uses a regulated variable power supply design which delivers constant power - regardless of the state of the vehicle charging system! The ZEN-POWER9 can also instantly adjust the internal voltage to deliver even higher power for peak periods. The internal DSP processor doesn’t just apply crossovers and EQ - it analyzes the incoming musical signal, and selects the most appropriate internal voltage level to deliver the needed power.
