Recently my left tweeter started hissing when I start the car/turn the HU on. It pops when I turn the car off. Then it goes away but the tweeter cuts in and out randomly. I took out the speaker and didn't find anything wrong with it and hooked it back up. Later while going to work, ALL the front speakers started cutting in and out, especially on the drums and snares of the song. It was wild. I don't know what the problem is.



I know it's not the HU because the bass wouldn't cut out. That leaves the speakers or amp. Or maybe that left tweeter is causing all the trouble?

I'd triple check all the wiring from the HU to the speakers as well as power and ground. If you can lay hands on another amp for troubleshooting, that'd be my next guess.
