My life speaker randomly goes out, then comes back on a few days later, but only for a bit, starts fading in and out, then out for a few more days.

the speaker isn't blown i've checked myself, the tweeter still works, just the speaker doesn't.

my setup is still 100% stock.

so my question is why would my speaker be doing thing? head unit problem? blown capacitor? and how do i go about finding out, and fixing?

thanks,
Cole
