Default Can anyone tell me WTF is wrong with my system?

I get this crackling sound from my tweeters. It didn't happen until I changed out my dash kit (yeah I know, weird eH?) I've changed RCA's, wires are ran on opposite sides, changed the grounds and everything. I have not grounded the HU (older Alpine CDA-7893) or the HU RCA's. Will try it tomorrow. Here's a vid of the sound.

Anyone have any suggestions? That crackle sound is there when the HU is on AUX (volume at 0) when its on CD and radio, all with volume at 0 so..

I believe you have induced noise. If your RCAs have a wire in them, you aren't using it for a remote wire are you?

What is the total ohm load on each channel from the HU? We dropped my buddy's down to 2 ohms per channel and it started doing that but when we had 2 ohms on the front channel and 4 ohms on the rears it was fine.

I don't believe they have a wire in them.

I believe the fronts are 4 ohms per side and the rears are also 4 ohms per side. It's safe to run two different final ohm loads on the same amp?

You can run 2ohm (or lower if the amp will handle it) per one pair and 4ohm on the other pair with no ill effect.

I've learned that tweets will not change the ohm losd, You can try what I tried and had no more probloems. Take every thing (the radio, eq, xover, )and run a seperate battery and with an switch on them, when I changed mine the clarity was amazing.!!!!!

^ I have my tweets/mids on some Cadence xovers. I guess they are passive xovers. Could this "static" be due to having 1 messed up xover to my rear 6x9/tweeters?
