I have a Dakota with a mid level Alpine deck in it, 18 RMS I believe. The stock speakers break up pretty early in the volume range, so I'm looking to upgrade. I went to Best Buy and listened to their R series and S series speakers. The S series was $50 less, and was only 2 way, but sounded much better dealing with the highs and mids. Their R series, a 3 way, sounded good with the mids and lows. Not what I was expecting. Anyway, since they are mixed, should I go ahead and pick them up, mount the S up front and the R in the rear? Should I just get the R series on all four corners? Despite the fact that the S series sounded better, I can't help but thinking maybe the R's on display had some issues with them. I might be putting an amp on them later, but I doubt it.
