Bonburner I'm actually using the 5.25" versions of the Reference in my Yaris running off only an Excelon HU (tuned the gains, placement, and distance of all speakers), which is why I'm considering them for the FR-S. The stock 3.5" speaker is a 4-ohm speaker, iirc, so the 3-ohm would definitely be louder than it.
But it seems like more people have experience with Daytons, so I will most likely go that route. I can always put them in the rear for rear fill duty should I replace them.
