Crackling speakers PLZ help!

[mode101]

I have been scratching my head on this crackling speaker. I need to ask the experts!

My setup is this:

avic d1 head
focal 165kp with crossovers in front
focals in rear (not sure the model)
jl audio 300/4 amp

The problem: very loud crackling noise from driver side door speakers coming from both the tweet and woofer, happens at all audio volumes.

Troubleshooting:
Since the fronts have crossovers, I swapped the driver and passenger door crossovers.. Problem stayed with driver door.

Next moved to the amp: I moved the RCA cables coming from head to the amp from left to right. Problem stayed with the driver side door.

Next moved to wiring: I had a spare speaker wire that I just plugged into the front left output on amp to the drive side crossover input. Problem still there.

OK, so in my mind, I have eliminated the crossover, a bad front channel off the amp, and the inside speaker wire from the amp to the front crossover.

What else is there? Someone please help!

Are the speaker leads grounding out out on the door?

do you mean at the crossover? i made sure that when i swapped the driver and passenger side crossovers I tightened the wires carefully.

i mean if the speakers are mounted to sheet metal, are the terminals grounding on the door

try hooking up another side of speakers to the driver side terminal on the amp if it crackles on the other speakers its the amp. if not try swapping speakers in the door to see if the speaker is bad. sounds like a bad terminal on the amp or bad speaker.
