I don't see why it wouldn't work. Give it a shot.

Could be defective, bad ground situation, head unit. First thing I would try, turn the amount on, recreate negative sound. Low volume. Now take a short piece of wire touch one end to the ground connection for the amp, and the other end touch to ground connection on rca (that's the outside ring) if it stops. Shut everything off, disconnect your negative battery terminal from the vehicles battery. Now go back over every bit of your wire job. Verify you have the correct wire size for length ran and projected amp draw.

Also, check every connection, power and ground, and not just on your amp, check the ones under the hood. Don't wrench then, just try to unscrew it with your hand. If you can, duh.

This will not only improve sounds quality, but it will save you cash. Bad connections drain battery, tired battery needs more help, helpful alternate gets tired, if alternator does not keep battery in top condition, starter starts to prematurely wear. Those three items are $500 and that's just parts.

Also, if the amp starved for ground, it will find one, at the RCA. Will burn up cable and fry the outputs on the radio. There is all the tools you need to succeed. Let me know what you find.

I had the same problem with my Pioneer AVH-P4000DVD. Just got my 16GB sandisk micro cuzer in the mail from Radio Shack. Here is what I did to solve it:
  1. Copied all the files that came with the Sandisk device to another location (in case I need them again)
  2. Copied all the music I had put on the Sandisk since I got it to another location
  3. Using a Windows PC, I right clicked on the drive in Windows Explorer and selected "format"
  4. I re-formatted the cruzer mini to FAT 32, default size (yes, I know it was FAT 32 already)
  5. Copied the music back to the cruzer mini
  6. Plugged it into my radio and it works GREAT! instant access to any track
Before you do this: Reformatting the drive also gets rid of the software that makes the cruzer mini copy files super fast. It will take a lot longer to copy music to the drive. For me this is no big deal as the only reason I bought the drive was to put a bunch of music on it and then leave it in my truck.

Hi,

A fix that often works for this problem is to pull the fuse for the radio from the fuse block out and leave it out for 10 minutes or so and then re-insert... HOWEVER, make sure you have the radio's security/unlock code handy because it will reset this and you will need to re-enter it after you re-insert the fuse and power the deck back up.

You could try removing the radio fuse for 60sec and reinstalling it. Sometimes this will allow the audio unit to “reset” and start working again.

If your talking about a Kenworth T680, static Is almost always a bad or loose ground connection. Did you add anything like a CB or new antennas?

Because of the multitude of possible problems associated with radio static in a big rig, you may have better luck in asking in a trucker forum. Someone there may have direct experience the same problem.

Good place to start.
