I was running the walmart scoshe brand RCAs and noticed that I had a ton of static and a small amount of engine whine when I tidied everything up in my truck. I saw a for sale thread here with the street wire RCAs for a good price so I thought I'd give them a try. Saturday I installed them and cleaned everything up. Went for a nice drive and found that all of the whine was gone and ~90% of the static was gone. Very well worth the price of $45 for 3 sets of RCA.

If you have tried everything like I had, try getting a pair of these.
