#PROT ON AMPLIFIER PRO#
Since replacing output transistors involves technical work, getting a car audio pro on board is better. These amplifiers are useful in high power protection testing applications when you need additional current and/or voltage sources, for critical high burden. If an isolated amp unit is going into the protection mode, there are strong chances that any of its output transistors have blown. Malfunctioned transistors are another reason why an amp gets into the protection mode. You can follow this guide to readjust your car amp’s gain according to the output of the receiver. When we say recalibrating the amp gain, we mean to match the amp’s input to the receiver unit’s output. If the impedance load is perfect and there is no ventilation issue, but your amp is still going into the protection mode due to overheating, you need to recalibrate its gain. However, if you have been using the car stereo system without properly adjusting its amp gain for long, it can result in background noise, distortion, and overheating. Recalibrate the Amp’s GainĪmp gain doesn’t have any direct link to moving the amplifier into the protection mode. If you find your amp extra hot when it gets into the protection mode, see whether your woofer/subwoofer system’s overall impedance load is in line with the rating of your amplifier. Operating on high power for an extended period heats the amplifier and throws it into the protection mode. When you connect a sub with lower impedance than the recommended load (e.g., connecting 4-ohm instead of 8-ohm), the amp increases its power load and works harder to match low impedance. Most of the time, this occurs due to impedance load misbalance. However, this thermal overload rarely happens due to the lack of ventilation or extended use. Check Amp’s Impedance LoadĪ car amp can get into the protection mode after heating up. Also, look for the blown inline fuses because they can also activate the amp’s protection mode. Make sure that all wires are securely connected without any shorting.
#PROT ON AMPLIFIER PATCH#
If the problem persists, check the power, ground, and patch wires of the amp.
Repeat the same procedure for the head unit. If your car amp is continuously switching to the protection mode, you first need to run a thorough inspection of every component connected to the amp.ĭisconnect the speakers and subs, and turn on the amp if it starts working fine, the speakers/subs might have developed an issue.
#PROT ON AMPLIFIER HOW TO#
How to get your car amp out of the protection mode? Instead, they should focus on how to get your car amp out of the protection mode. We would strongly recommend our readers stop finding solutions to bypass the protection mode on a car amp. Even if you find one and start using your amp while it was still in the protection mode, you are most likely to damage it for good. There is no legitimate way to bypass the protection mode on a car amp. Many people get frustrated by this inability to enjoy the music and start asking around and searching online “how to bypass protection on a car amp.” When an amp goes into the protection mode, it shuts down and can’t let you use your sound system anymore.
