Disconnect all of the speaker wires and signal cables from the amplifier.

 

If the amp still goes into protect when you power it up, the output transistors are likely shorted.

MY soundstream LiL Wonder 4.620 is only going in protection mode


Disconnect all speakers Meter power, remote, ground at amp, if all is good move on, if not check main fuses
Turn amp on; If in protect mode then your amp is toast Turn amp on, if not in protect mode then start reconnecting speakers one by one until your amp goes into protect mode, then you'll know which speaker is bad.

Lightning Audio b2.3000.4 is in protect mode. i removed all speaks and conected the amp directly to the battery and it still stays in protect mode. what can i do to fix this problem?


  • Only a select few things can cause protect mode with the battery only connected.
  • An installation issue. Check the Power, Ground and Remote wires. Make sure non are shorting from one terminal to the other.
  • It is still overheated and has not had time to cool down from being in thermal protect mode.
  • The amp itself is touching metal. You always want something non conductive between the amp and where it is mounted, this includes the screws being used to anchor the amp. They should never touch the metal in the car either.
  • The final thing that can cause an amp to go into protect mode while only hooked to the battery is the amp itself is malfunctioning and or defective. You can try opening the amp and look for any black spots on the circuit board where an electrical component might have smoked up or blown and replace that part.

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.

Power light turns from green to red protect mode and then there is no sound coming from my speakers


there are 2 reasons for it to be going into protect mode 1 is heat 2 is the load on it. if it is going into protect mode soon after it starts there is a problem with the speaker. if it is after it has been on for a while it is that the amp itself is overheating. hope this answers your question

It's very likely that the output transistors have failed in the amp. They will need to be replaced.
