Subs cut in and out


The amplifier may be going into protect mode (even briefly) because you are driving them too hard. Back off on the volume and see whether the problem goes away.

Hi i have a kenwood A-97 keeps saying protect on the amp can you help


Hi,

The amp will go into protection mode when there is a short in the speaker wires or the amplifier was overloaded. verify that none of the speaker wire connections are loose at the back of the receiver or at each speaker. And verify that none of the wires are making contact with each other.

if it is, then remove the speaker wires and connect them again properly. After disconnection g the speaker wires, unplug the receiver for 10 to 15 minutes. This will make the overload protection back to normal

Try this and let me know. I hope this would solve the issue

Regards.

I have a punch p850.4 amp that goes into protect mode as soon as its powered up , have checked and double checked all connections to make sure its all hooked right . even downloaded the pdf for the amp .


I have exactly the same problem, try a different speaker wire from your sub terminal to your amp terminal, if no luck you may have a loose connection on the wires on your sub, due to vibrations etc they can sometimes come loose, but very rare. worth checking though. 1 loose connection can make the amp go into protection mode. If all of these are fine, start from the beginning, ( I have tried this and i think its my speaker wire shorted out) 1st dissconnect all wires from amp. Then connect ground first, then your live. then power up amp, it it works andd not in protect mode your earth and live are fine, then connect your remote, then test, then speaker wire , then test, that way you can rule out bad connections and find any fault.

Trying to increase volume on car deck when doing so the amp just shuts off, then amp makes a burning popping sound and smells like something burnt up and 3 sec later amp kicks on and still works, none of...


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

Unit only stays on for 4 seconds then turns itself off.


This is a short or unstable ohm load. Remove all speaker wire connections to see if the amp will stay on.
If the problem goes away when disconnecting the speaker wires try this:
1) Check volume level on zone one and zone 2 if connected. If it is too high the amp will go into protect mode and shut off exactly as you described.
2) Make sure no wires are touching any other wire or the metal surface of the amp. This will cause a short and send the amp into protect mode.

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.

Protection Light Is Coming On


You say the protection mode only occurs when you plug the RCA's in. Does it have to be both RCAs or just one?

The other end of the RCA cable is plugged into the HU?

It possible the RCAs have too much DC voltage on them, causing the amp to go into protection.

Is there a short in the RCA cable?

I would definitely check out the RCA connection at the back of the HU, as it sounds like there could be other issues there. Make sure the RCA connectors aren't touching any other metal (especially +12V).

Amp goes into protect mode.


I would definately suspect wiring. If you can use a volt meter. Put it on the b+ to ground and see what the reading is should be 12+ then try the ground to remote wire should be 12+. If it drops below 12 volts when car starts. Recheck wires for loose connection. Also double check the wire you have the remote wire connected to. You might even want to disconnect from the amplifier and use a jumper wire from the positive terminal on the amp to remote on the amplifier and see if it stays on then. If it stays on you will have to find the loose connection or find a different wire to get remote power.
