but is not solving the root problem was the point, and fixing a ground is free the isolator is not


I am just trying to correlate that this is the same process as used in college logic 212 or in differential math or in any other logical process we engage in every day

....the more trouble shooting you do and the more you try ... and try... and try to teach others how to do it on their own the more you try to simplify the thought process

 

I hear ya John... but the root problem is generally in the equipment and not the install... so troubleshooting is out...

 

I used a canadian tire noise filter. in the dash, only for the HU and interfaces. It stopped the clicks from when the car turns things on and off, wipers, rear defog, etc.

 

Well i grounded the deck's ground to the amp in the trunk and viola!
No more noise...
woo hoo.!!!!!

 

i need one for my fm antenna lol, i get serious noise after about 30 mins of listening to the radio

 

you can get isolators through DLC distributors, check out there site "DLC distridutors.ca"
cheers

 

you need to source the problem instead of masking it imo..

 

sorry just read the rest... glad to hear you fixed the issue!
