Ground loop isolators do not resolve the problem they only mask it. I would suggest to anyone to fix the problem correctly first. There are a handful of steps involved in troubleshooting noise and not all situations are the same. a bad ground and a ground loop are not the same thing, they could be from a similar cause but both may require different repairs. As I said before 9 times out of 10 (maybe I should have said 8 out of 10). dnorrell's case may have been one of the 1 or 2 out of 10, or maybe it was a different ground that needed repair, or maybe (and I'm not trying to offend) his new ground connection, location, or length was not good.

 

No offense at all; we are here to help one another so I am always open to new ideas

Being an engineer, I took a very systematic approach to resolving my problem (granted, I was running low on patience). I had tried several different approaches to the ground (paths, location, wire, etc), but none made one bit of difference. I would argue that ground loop issues and "bad" grounds are very much related though, and I consider my issue more resolved than masked as the only symptom evident to me has disappeared. I wholeheartedly recommend taking a long look at working through various ground options first, as that is the more likely culprit. There are some great tutorials online if you google something like "car audio ground buzz" or the like. Good luck and keep us posted!

What was the fix? I have the exact same situation as you? I'd really appreciate it if you could update with your findings.

Cheers

 

I'm having the same problem. What was the result of this?

 

For me, I ended up ripping half the truck apart before deciding to just run new wiring/speakers/amp.

In doing so though, I decided I wanted to tap into the factory wires up front for my rear speakers rather than run new rear. That is where I found a splice that someone had done to still keep the rear subwoofers working.

If you have an aftermarket deck and your subs are still working, I'm willing to bet you have that same splice.

After finding that though I still went ahead with the new setup.

 

BUT DID YOU GET THIS FIXED AND HOW?!?

This is exactly the problem I'm having.
