Question
in my Nissan spec-v 2002, i put a jvc radio, i have the stock amp and sub. There is no more sounds coming out from all of my speakers, it work for a while, but suddenly no more sounds?

Answer
Don't know this car so I cannot imagine what the interface and wiring would be for the stock amp/sub and you did not give a model number on the JVC so can't be very clear with you about that.

So, here is what might be going on - guessing as best as can be done:

ONE:  The amplifiers maybe went into protection mode from overdrive.  To reset, remove power from them for a few minutes then power them up again.

TWO:  You could be overdriving the input of the amp due to a high output from the JVC. If it is too high it can overload the input circuits and wipe them out.

THREE:  The JVC radio has maybe developed a failure problem internally.  Do the lights come on the front display of the JVC?  If no lights you have taken out a fuse or the 12v wiring has failed.
