SOURCE: Protection Light

This is almost always caused by shorted output transistors. To eliminate other possible problems do the following.

Disconnect all speaker wires from the speaker terminals of the amp and disconnect signal cables from the amp. If it powers up, the wiring needs to be checked. If it still shuts down (goes into protection), the amp likely has blown output transistors.

Generally, an amp with blown output transistors can be repaired.

My mtx JH300 amp is going in to protection mode what should i do?


have you checked the amp fuse ? also never connect while battery is connected. be sure to connect the amp to amp specs as stated in user manual i had the same problem and it was as simple as a missed connection however it could be a multitude of isues causeing the problem most of which are in the user manual. also check the earthing cable is hooked up and be sure no power supply is earthing out on the car. Protection mode is generaly activated when the amp isnt connected properly or by fault of power supply. double check evenrything and check again.

I have the same sub combo. The problem is the amp is underpowered for the 2 MTX 12s, get a bigger amp and you should be fine.

Light


The red light indicates that your amplifier is in protect mode. Amps go into this mode if there is something wrong with the setup of the system to prevent fatal damage to the amplifier circuitry. This is bad thing since the amplifier will not function until the problem is solve and it can remove itself from protection mode.

Amplifiers can go into protect mode for many reasons but one of the most common is incorrect mounting. Is your amp sitting on the metal of your vehicle? Is it bolted down and screwed into the metal of the vehicle or your seat? The amp should never be touching any sort of metal. Only the ground should touching the metal of your vehicle.

Speaking of grounds, many people often neglect proper grounding which can cause an amp to go into protect mode. Do you have a solid ground? Is the wire less than 3 feet long and directly connected to a non-painted metal part of your vehicle? Is the ground wire the same gauge as your power wire?

These are just a few reasons why an amp can go into protect mode. You can find more information here. Or simply google for why your amp is in protect mode.

Lanzar Vibe 1200D protection light


You will need to show it to a service technician as it seems the output section has blown so it remains in protect mode. One reason (could be) that the input to the amp was high and may have been clipping for some time before the amp decided it could take it no more
