Speakers can not handle the load so the coil in the speakers heat up and shut off your amp.

Protective mood


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. Hopefully its not toast. .A thumbs up would be greatly appreciated if this answer is helpful to you. protective-mood-zb4bomd1rt4qms0dqd12kkt2-2-0.jpg

Power amplifier kenwood, power led blinks, no sound


There will be noaudio coming out , if the protection circuits is

sensing a fault or overload , just to protect your precious speaker

from further damage ( or the amp itself ).

These needs servicing.

Why does my sub and amp go into protected mode when i turn my headlights on


Hi.

Devices go in protect mode when a fault condition is detected. These include insufficien voltage, excessive load, shorts and contact, overheating.

In your case the problem is usually excessive power draw. A contact in wiring can also cause the problem, but this is far less common.

Use a capacitor fix the excessive power draw from the amp and sub.

See:Capacitors - BOSS AUDIO SYSTEMS

BOSS AUDIO SYSTEMS SE950 Car Audio Amplifier: I have a SE950 boss amp, hooked to 2 audiobahn 12"...


Sounds like you are over working this amp for sure.. Upgrading your power wire & battery might help, check your gain level on your amp to. This is not the volume for the amp. Its to get both amp and the cd player on the same page... And most of all if your subs are wired up to .5 ohm stable, see if your amp do the same... My answer to this ?? Upgrade your amp, Boss audio was never a good company to me, but that is my opinon. Audiobahn set up all the way..

My boss amp is on protection mode and it wont work its a 3500 watt chaos idk what is wrong with it


Likely one of the power amps has failed component(s) and does not achieve electrical balance which then goes to protect mode to prevent damaging your speakers.

You will need to have it serviced.

Red status Light


If the protection LED is lit, the amp is in protect mode and probably has shorted output transistors. To eliminate other possible causes, read through the following page:

Amp in Protect Mode - Trubleshooting

Let me know if you have any other questions.

Low amp output


Make sure the BOSS isn't in "Protected" mode (Red led lit) and connect the speakers properly (check the connections if they are in "bridged" mode).
Also, make sure you set the cross-over, bass boost setting, bass volume control and the bridge mode according to the speakers you are connecting. Check the input level too.
The BOSS amplifiers are of very poor quality and it can be easily broken. Maybe yours is broken.

Amps


It sounds like the output transistors have failed. Disconnect all of the speakers from the amp and power it up. If it still goes into protection, an output has almost certainly failed.

 

To repair it yourself, you'd have to find the defective one, purchase the replacement parts and replace the parts in the circuit board. 

 

This type of damage is often caused by driving an ohm load lower than that recommended by the manufacturer.
