Not sure whats causing this?

Just finished my install last night and cleaned up wiring this morning. Car was sounding great while running errands this morning, but then when we left to go to gym around 6pm the speakers were making a crackling noise. It happens on al sources, radio, cd, bluetooth. I checked voltage to amp and its 14 volts while car is running. Fuses look good everywhere, rcas and speaker wire are snug.

Not sure what the deal is? Maybe a bad ground? I ground it under the back seat and used a dremel to clean off any paint, so its going to bare metal.

Forgot to mention this is a FSD 125.4, 4 channel amp for my mids and tweeters.

Hmm.. are you sure it was 6pm?

If it were 5pm, the most common issue would be insufficient ground under load..

But, if 6pm, i would say perhaps one of the speakers are grounding out in the door possibly or somewhere else.

Ironically.. still a grounding issue, but at a different time = different place //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

If a speaker were grounding out in one door would it cause all speakers to crackle?

If all the speakers are connected to the same amplifier, yes.

However, the question itself is limiting your troubleshooting.

Don't assume anything.

Something isn't right so expect anything to be the cause of the problem.
