Replace Alpines with Infinity Reference 4002CFX. The Infinities are slightly lower rated for power (35 watt continuous vs. 45 for the Alpines) but have a much better sensitivity of 92db vs. the Alpine's 86db. That 6db difference equates to 4 times the volume at the same input power level. This means the amp doesn't have to be driven so hard to produce the sound.

The improvement in midrange is considerable. This really helps "fill out" the sound, from the rear speakers. Even at the highest volume level the Alpines could not produce the same amount of low/midrange as the Infinities do at half volume. The Infinities are rated at 75-21kHz. The Alpines at 97-22kHz.

One note, the Infinities are a slightly deeper speaker and magnet bottomed out on the passenger side (1 7/8" vs. 1 11/16".) It doesn't seem to cause any issues with output or vibration noise. If I were to do it again I'd look for a shallower 4" speaker with the similar efficiency and performance.

Discovered another "surprise and delight" with the Pioneer 6200. When listening to a CD a little red symbol would sometimes appear at the lower corner of the screen. It was the road speed limit and it would flash on any time I exceeded the speed limit. Nice touch.
