I bought new radio and speakers from Crutchfield and installed them a couple months ago. I’m now changing the rears to 6.5 inch and moving the 5.25 inch to the fronts and adding Rockville tweeters. I misplaced the wire splicing guide that Crutchfield sent me so I found one on the12volt.com website. The chart on the 12volt.com shows I had the front speakers wired wrong but now I found the Crutchfield sheet and I had it wired it correctly per their sheet. Since I wired the radio harness using their instructions would I be safe saying Cruchfield’s sheets should match? Or is there a way to test them? The wire colors for the rear speakers match on both sites so who is correct for the front ones?
