You probably blew out the sub, the larger speakers are more at risk to distortion are high output levels. The amp can no longer maintain its true output and begins passing voltage to the sub and the cone over travels or the winding burns out. You can try gently pushing on the sub membrane to see if it moves in and out easily, it may be stuck and you can free it up. If that doesn't work, remove from system and check the coil with an ohm meter resistance. it should read a low ohm value. If high value, it's blown and you need a replacement. It is also possible you blew the network that sends the lows to the sub and the high to the mid range and tweeters, check the sub first.

You may have blown a fuse, check those to make sure they aren't blown. Verify that the connections are in place again and make sure the settings on the amp are correct as well.
If the fuse isn't blown and the connections are secure, I would make sure that the wire that you have ran from your battery is within the specifications for use with your amplifier.

JBL amp, worked fine untill 2 days ago. protection light on..


might have roasted your speakers voice coils a little which may be sending the amp into protect mode throw a speaker on it that you know works and if it doesnt trigger the protect circuit then you probably have a blown or almost sub.

Amp burned out but fuses still good?


this is caused by inproper wiring from the speakers/subs to the amplifier.. an amp will still put out power to subs and speakers when it's wired improperly but it won't last for very long doing it... 6 months is longer than usual....

Subs cut out


although an odd thing to have happen it does sound like you blew your amp. check the fuses in it to see if you can avoid having to replace the amp and instead replace a few dollar fuse also check the fuses where you had this pluged in. hope this helps a little. if you give the amp type i may be able to help a little more

I had my subs installed a month ago and a few days ago the subs are working,everythings connected but not working and my subs aren't blown out because i don't have my music that loud so whats the problem?


what model kenwood speakers do you have? what head unit do you have? do you know how they hooked up the rca cables to the back of the deck? if this deck has got 3 pre outs you may have lost the sub pre-out. are you amp lights coming on? if you are still having problems you can take a 9v drill battery or bigger and touch the wires from the speaker to the battery, make sure positive to positive and neg. to neg. the speakers should pop if they are ok, that should re-assure you on the speakers. let me know and ill help where i can. good luck

Lanzar Vibe 1200D protection light


You will need to show it to a service technician as it seems the output section has blown so it remains in protect mode. One reason (could be) that the input to the amp was high and may have been clipping for some time before the amp decided it could take it no more

Protect light flashing/ticking


this problem sound like you have too low of power going to your amp, test your battery and make sure its putting out enough power for at least the mininum amount of power that your amp requires, you can find that information in your manual or sometimes they post it on the amp itself. i hope this info helps
