Some amps go into protect mode if they get too hot, which can prevent a permanent failure. The common cause of overheating is a lack of airflow. If the amp is located underneath the seats, or in another confined space, that may cause it to overheat.
How do I get my amp out of Protect Mode?
If you find that one pair of speaker wires or one speaker causes the amp to go into protect, disconnect all speakers from the other end of the wires and separate the wires so they can’t touch. If the amp still goes into protect, you have a bad speaker wire or the wire is shorted to chassis ground.
Can a bad ground cause an amp to go into protect mode?
Step 4: Check that you have a good ground
If it reads more than 0.1V, your amp is almost certainly in protect mode because of bad grounding. To solve a grounding problem, clean your grounding wires, then reattach them more tightly to a location in your car where you’re certain they won’t rattle loose.
What does Protection light on amp mean?
The BX250 and many other amplifiers use the same solid red light to indicate both that the signal is muted and that the amp is in protection mode. If your unit goes into protection mode, it is a good and bad thing- good that further damage is being prevented, but bad in that it may delay the gig.

Why are my subs cutting in and out?
Make sure all connections are tight at the amp, make sure your ground is snug (you may need to take this one a bit further and verify that it’s a good spot to ground to in the first place), make sure the connections are tight behind the head unit, and make sure your power wire has good contact with the battery (don’t …
What will a bad ground do to an amp?
Bad grounds can make your amp cut out, and create excessive heat, which can lead to vehicular fires. … Without a good ground, your system cannot create this current, which creates clipping issues with the amplifier. Properly grounded systems help stabilize voltage levels.
Will a bad ground make your amp hot?
There are several different reasons that an amplifier will get hot and shut down. Four of the most common are: Blown/grounded speaker(s), poor power and/or ground connections, too low an impedance (load), or Gain/Punch Bass control settings too high.
