I bought Pioneer for an Escort, and didn't like them. Slow to learn, I also purchased 4 of the Pioneer A68565 for my Mystique, and was very unhappy with the results. I was using the stock "80 watt - haha" premium amp, and the speakers sounded very harsh to me, and bass was reduced. On my next car, the Contour, I bought Kenwoods 6X8's that fit (I can get exact model if you want) and they were much smoother, better bass, and cheaper $79 vs. $99 Pioneer's.
Also, I used Crutchfield, and word of caution - they will tell you that only 2 Pioneer 6X8 models will fit Contour exactly, and technically this is correct because you can use existing screw holes (no drilling), but as I found out with the Kenwoods, drilling is no big deal, and the instructions Crutchfield sends for door trim panels makes it pretty straight forward. My advice, avoid Pioneer.
