I thought replacing my front door speakers should be no problem. So I picked up a set of 6.5" Infinity speakers. 2 hours later while being interrupted a half a dozen times by the phone ringing the thought of the $50 Best Buy wanted to install my speakers was starting to seem like a good deal. Never did I think that installing a pair of speakers could be so much trouble. After I got the drivers side in I decided that I should button every thing up so I could get ready and go to work. At this time I though I should turn the radio on and see what the one new speaker sounded like. This is the best part, now I have no sound at all. Not anything from any of my speakers. Is there something to not having a matching set that did this?
