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.

Protection Light Comes on


Sounds like you have an ohm problem, Tryy hooking the positive from one speaker to the negative on the other speaker. Then hook the negative from the first speaker to the negative on your amp and the positive from the second to the positive on the amp this will drop your ohm load and the amp should stop going into protection.

Protection light coming on and amp cutting off


yes make sure there both connected properly, check the fuses, the protection light usualy comes on when there is too much power and the amp protects itself from blowing

Protection light grief


Disconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty. Hopefully you have warranty. Vibe is mediocre. Time to invest in an old school Lanzar Opti Drive amp. .A thumbs up would be greatly appreciated if this answer is helpful to you. protection-light-grief-shonxoarcym4awy4zl1imx4o-2-0.jpg

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
