Chris, I had a funny feeling that a cap was just what you needed. I am glad to know that it did indeed solve your problem. I will be busy this weekend installing new custom stereo in my XF now that it is above 20 degrees. I will let you know how it goes, starting w/ all new infinity speakers throughout (all component), 2 caps, and a single 12 to start, may add another one down the road haha.
