When i turn my Kenwood excelon kac-x811d the red light flashes and it shows a error 03 code

This indicates a short somewhere in the speaker wires according to the manual. Check connections at the harness of the deck (if you are powering the speakers from the deck) for shorts, or if there are no connections ensure that the loose wires are taped off to prevent shorting (touching other wires, or metal). If you are using an external amplifier you can shut the internal amp off in the deck as well (This will improve the deck's performance).

Amp is probably going into protection mode, or does not have enough current from the power wire to continue operating. Check that the speaker wires are not shorting out against each other. Also check your power wire and ground wire. Ensure that the amp is solidly grounded. Are you using the proper gauge of power and ground wire? (4awg recommended.)

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. Please check impedance on speakers as they coyld be fried as well. A thumbs up would be greatly appreciated if this answer is helpful to you

Red Power Protector light

Hi, the only way i can see the amp resets the stereo is that power is dropping. The amp should have its own wires directly to power/battery so as to not affect anything else.

On the protect, try to disconnet all the speakers, make sure the power is OK. If it appears to work, the there could be a problem with speakers/cables. Try a different speaker to see if it works. If the problem continues with speakers off, a different speaker etc, then there is a problem with the amp. Hope that helps

Amp Power light will not go on. Protection light is lit- Thump sound in speakers

It probably has shorted output transistors. To eliminate other possible causes, read through the following page.

My amp turns on and off

Sounds like there could be a short somewhere. Check to make sure that there aren't any (exposed/bare) wires touching each other or if there is a bare spot of wire touching something metal. Check both ends of all the wires. A speaker wire may have come lose and is shorting out against the frame or some other place. Usually if it goes straight into protection mode or you're popping fuses you have a short somewhere. I assume the capacitor you installed is somewhere on the power line, which would be for helping with
noise. You can also try disconnecting your amp from your stereo and see what happens but leave the speakers connected, you don't want to run the amp with out a load on it (the speakers). If your amp doesn't go into protection mode when the stereo is disconnected, then you have a problem with the stereo and not the amp, assuming you already checked for any possible shorts first.

Stereo System Not Working

Often time, if a speaker wire gets "grounded out," in other words when a speaker wire gets shorted to the chassis of the car, it will prevent sound. Best thing is to check through the system with a multimeter

Amp blowing fuses

The amplifier probably has shorted output transistors.

Disconnect the speakers and RCA cables. Replace the fuses with two 10 amp fuses or a single 20 amp fuse. If the amp blows the fuse when it powers up, the outputs are almost certainly the problem. Don't try it with the two 30 amp fuses. The smaller fuses will provide more protection for the power supply. If the amp powers up with the smaller fuses and they don't blow, check the speakers and the wiring (for shorts to ground or shorts between wires).

No sound

you may have a blown speaker...many cd decks will shut off their audio circuits when a speaker is blown to protect from shorting out. Go to the back of the deck and try disconnecting speakers one by one. You will have to turn the deck off and back on each time. Hope this helps!
