The Speaker Protection Board 0–12V AC Red ICE Series is a reliable safety module designed to protect high-power audio systems from speaker damage during power-on/off surges and DC faults. It is suitable for use with 1000W stereo amplifiers and 400W stereo amplifier setups, making it ideal for home audio, car audio, and professional DIY amplifier builds.

This protection board operates on a 12-0-12V AC power input and uses a dual 7A 12V DC relay system to ensure stable and safe switching of speaker output. It effectively prevents speaker “thump” noise and protects valuable speakers from DC leakage or sudden voltage spikes, enhancing overall system safety and longevity.

With its simple and compact design, the board is easy to install and integrates smoothly with most amplifier circuits. It is a must-have safety component for any high-power audio system where reliability and speaker protection are critical.
