My tweeters are dash mounted w/ a black and red wire attached to it. In an attempt to cut noise from my system, I twisted the wires together on the driver's side only. I started at the bottom of the tweet down to the end of the stock wire. From there, it connects to aftermarket wire that goes to the crossover.
I'm not sure if I can describe it, but I'm quite confident that it sounds different than the passenger side which leads to my question. Does twisting speaker wire together do anything compared to being attached together running parallel?
