Disconnect the sub or speakers and turn on the amp, see what happens. If the amp turn on without the protection light, then your sub is blown. Also check to make sure ALL your fuses are good including the one under the hood. If you have a meter, test the fuse for continuity. The problem can also be a bad ground.

Kenwood kac 628 red light comes on and no audio output

The red light you describe on your amp, is the protection mode warning light. An amp goes into protect for many reasons. Here's a checklist.

1st check the fuse (s) on your amp and make sure they are not blown.

2nd check the inline fuse next to your car battery (if you have an inline fuse)

3rd, disconnect the speaker wires with amp on, does the light go off?

4th check your ground, this may be ok if you have tried another amp with the same wires.

5th.if none of these turns the protect mode off, it may be an internal fault.

you may have blown transistors and it is a tricky job to repair and costly.

The protect light is on because there is a internal problem with the amp, causeing it to over heat,

The red protect light is coming on

It is possible that your amp is going over the threshold limit of draining current to give out the protect signal. What could be done is to first checkout if your speakers are loading the amplifier, check the rating of the speakers and the impedance, must not be too low.below 2 ohms. Now check the source signal if this is bringing in any transcient signals to power out the outputs particularily high/low freq. So decrease off your bass and treble to mid position and test again. see if there is any improvement, if so there could be a filter problem with your set. Connect an external source and see if the amp powers better , in such case check for fault in cables, input lines and ground with in the set. Repeat this and check. Hope this helps you out. Good day

Speakercraft DBB12100 Amplifier, Circuit problem

Sounds like its a problem with over heating. open unit clean out all dust and dust bunnies wich compressed air. check that all fans are opperating. (fans on 6x100 amp units or thermal controled). If amp goes into protection prior to fans turning, there is your answer. the @ power supplies will have a green light on the output side. if the light in on power supply is good. or you can check that the output voltage is at 48Vdc on both units.

Hifonics brutus bxi 2008 amp. no power output

Amp powers on, no sound from subs

the output is blown. It is in need of service.
There are many different ways that an amp can fail but the two most common failures are shorted output transistors and blown power supply transistors (< those are not blown). There are several types of protection circuits in amplifiers. The most common are over-current and thermal. The over-current protection is supposed to protect the output transistors. Sometimes it doesn't work well enough to prevent the failure of the output transistors but it will work well enough to shut the supply down before the power supply FETs are destroyed. If the amp remains in protect mode, goes into protect mode or blows the fuse as soon as the remote voltage is applied, shorted output transistors are almost certainly the cause.

Sony explode amp for my car

Try disconnecting everything but the power connections. If the protection light still comes on, then there's a problem in the amp. If it goes out, then there's a problem elsewhere. In that case, hook up one speaker cable at a time and power on. If the protection light comes on, then either that speaker is bad, or you've got too many speakers connected to that one amp output. Too many speakers connected together can cause an overload and trigger the protection circuitry, or worse, blow out something out.

Hope this helps, and please rate my advice.
Thank you, and good luck!!

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.
