Alpine S-A32F S-Series 4-Channel Digital Amplifier - 80 Watts RMS x 4 @ 2-Ohms The S-Series amplifiers were designed to perfectly complement the already established and loved S-Series speaker and subwoofer line that Alpine Electronics has continually improved for years. The S-Series Amplifiers have a diagnostic LED located behind the blue Alpine Jewell on the top of the amplifier. A Blue light means the amplifier is operating normally. A red blinking light means the amplifier is currently too hot for operation and needs to cool down. A solid red light can mean three things; 1. Amplifier circuit is abnormal. 2. Temperature is too high. 3. Power supply voltage is too high.
