Default Help troubleshoot Audio Crackle

I have done a bunch of reading of problems existing with the crackling of the factory sound system. I found that the ones that were fixed are different symptoms than mine. I don't know if there is an amp in the system that I am not seeing. I have a 2002 WRX wagon that has the factory sub (unhooked). I have had a terrible crackling noise in in the audio system. I does not get any better when I am driving or with the engine off. It is ok as long as I do not turn it up to where I can hear it. My first guess was bad speakers. Here is what I have done:

I replaced the front door speakers with Kenwood Excelon's.
I replaced the head unit with a Pioneer AVH-X2600BT

The crackling is still there. I have new speakers to go in the rear also but haven't done it yet. Do I need to run all new speaker wire or is there an easy fix for this?

Thank you in advance!!

wish it were white


If you turn the bass down does it get better? If so you might want to cross the speakers over around 100, that is if your head unit has an electronic crossover. If not you might have to throw some capacitors inline.

I would suggest your next troubleshooting step is to determine if there's an issue with the wiring.

It's unlikely that you just have "bad wire." However, there may be a break in the wire that is causing issues. Or, there may be a short at either end near the connections. Try taking a direct path. That is, grab some speaker cable and run it from the back of the deck to the speaker itself. You should remove your deck and your speaker while you do this. Just run the cable externally - no need to re-route it through your dash.

If you're still getting the crackling, then it's not the cable. If you are, then look for obvious shorts. Look for cable fraying, etc.

Another obvious question - have you isolated which speaker is crackling? Is it all of them? Or just one.

If it's all of them, it's highly unlikely that it's bad speaker cabling. It's more like a bad ground or similar. If there is an amp in-between, the ground could be a problem at it, or at the head unit. Or, of course, if there's an amp in between, it could just be toast.

You shouldn't need to HPF a pair of Kenwood Excelons. You should easily be able to run those full range and have no problems. Granted, a gentle slope at 50Hz may be better for your overall sound, you shouldn't be having audible distortion at the volumes you hint at.
