i have all factory h/k stereo. this morning the radio stopped working and a loud pop comes from the speakers about every 5 seconds. i turned the radio off and it still made the noise. i turned my car off and back on and it still makes the noise. any idea what this could be?? please help! thanks.

 

Is your battery good? Alternator going bad? Autozone can check these things with their battery cart.

If it's not that, then I have no clue what it could be.

 

Most likely the H/K amp giving up the ghost.
