Definitely check your wires, you don't want a short under the seats as it can also result in a fire. Also, if the amp is completely covered and there is no air circulation it will overheat and shut off. Make sure it's well ventilated.

Please accept my solution!
Thank you for consulting Fixya!

red light = internal short usually.

that is the way it works, I assume it is a car amplifier here,please accept my apology if I am wrong.Normally these amps are powered on by the radio/cd player.It has a wire which connects them together which wakes up this amp when radio/cd is powered on.Hope I have answered your question.

A stereo or amp, either one should have a fuse, fuses for radios would be in the wiring harness behind the radio deck. An amp fuse should be obvious were they insert in the fuse blocks by the amps main power cable connector. If you see that all fuses are fine then check your ground wires if not then your radio is bad.

1st you have to open it with removing bolts of it. then there is lock with the belt it can change easily then change the belt

Check your ground. Make sure you sand off any paint where you grounded the amp. Also did you hook up the remote wire? It's the blue wire on the back of your headunit. Some say remote wire, others say power antenna either one will work. Sounds like one of the two...hope this helps.

That amp needs 4 gauge power and ground wire minimum. Too small of wire is just like using too small of a water main to a house....it's just not gonna work out

Hola! Puedes buscar un manual por tu radio en el website de Kenwood por supporte.
Solo necesitas a buscar tu numero del modelo de tu radio y puedes copiar el manual ...no cuesta nada... checkas AQUI

put a fuse on your amp power wire bout 12" from battery, run wire to your back of car make sure you have a good ground wire hooked up and a remote wire from your head unit (blue) to the amp and run the speaker wires and you should be good to go. make sure you get the right gauge of wire for you amp. hope this was helpful

make sure to double check your remote wire and to see that it is connected properly

disconnect load (speakers), check if it still goes in to protection if so then your output stage might be faulty

Has the amp been overheating lately? It's quite possible that the amp could have just blown. Smell around the outside of the amp for an electrical burnt smell. If available, see if a friend also has an amp hookup and try removing your amp and copnnecting to the friend's cables. That will tell you if it's a wiring problem or an amp problem.

Does the car start with the voltage dropping like that? Sounds like a bad battery. A battery can show 12.6 volts and as soon as you put a load to the battery the voltage will drop. I would change the battery and see if that helps. Also check your alternator. Get a DMM set to DC volts connect it to the battery and see how far the voltage drops when the cars running. You should see something like 14 volts or so. If it drops below 11 volts you may need to upgrade the "big 3" wires...hope this helps

the red light is for power in protect mode it should be orange and it will not emmit sound if you think you should have better sounding bass or more bass you can try to play with the gains on the amp or possibly if you have the negative or positive hooked up wrong from a speaker to the amp this will cause the bass to be lower and somewhat distorted double check your positive and negative wires from the speaker to the amp and make sure they are correct

you need a new amp that one is toast
