Just got through tuning the new amp/speaker combo from Wayne (firecap). I did the mini amp, 6.5" fronts and 5.25" rears...I took it a step further. The amp is solid down to 2 ohms, dont hesitate to run the front and rears in parallel. It sounded good with the amp running the fronts (4ohm), but it completely kicks azz in the 2ohm. This was a very good mod and money well spent.
