[QUOTE="blazian87, post: 8709530, member: 574798"] I did some reading and found out that once the red light turns on, it's reached its thermal limits and then it activates Advanced Rollback Protection... [U]This is what JL says:[/U] "Should a JL Audio amplifier equipped with Advanced Rollback Protection reach an unsafe operating temperature, a special circuit rolls back peak power output, without changing gain, until the amplifier cools down to a safe operating temperature. The red "Thermal" LED will light to indicate this condition has been reached. Once the amplifier cools down, the circuit restores full peak power output and the red "Thermal" indicator reverts to its normal state. The operation of Advanced Rollback Protection is inaudible in most cases, but it ensures that your music keeps on playing, even under the most demanding conditions. Featured in XDv2, HD & Slash v3" So I guess it's automatic but still not a good thing to reach it so quickly all the time. [/QUOTE]
