Crutchfield has a well-deserved rep for being very customer friendly. I lost interest in car stereos though once I had a house where I could jam. Did your wife kick you out RJ? Do you spend a lot of time in your truck?
I find the stock stereos in the Silverado and the SRX pretty damned good and louder than I need these days. If I really want to get into some music I prefer my garage Frankenstein system built from garage sale acquisitions. Something about a good garage stereo that can't be beat. Really booms. Maybe it's because of the old big woofer speaks that I have in the upper corners.
