Maybe time to sneak in some 2"~3" at the base of the "A" pillar of the 4Runner. I vote Fountek, Fostex or maybe Dayton. You heard the 4runner first hand and would know what I should use. Plus you know how bright I like my music. Don of SDS has the TB W3-1364's: http://www.parts-express.com/pe/showdetl.cfm?partnumber=264-844 They were brighter than my Founteks, maybe a little more on axis demanding, but also a pinch more towards your ear on pin point precision compared to mine. The Aura 3" FR I have in the bedroom towers, are REALLY impressive for the price, but personally I think the Founteks are a pinch better for in cabin. These TB's caught my eye: http://www.parts-express.com/pe/showdetl.cfm?partnumber=264-812 before I bought what I have now. I love underhung top end, as what I have now are, but these are more competitively priced. Sean did not seem to like them all that much if I remember correctly, along with the TB 1878's I ALMOST pulled the trigger on. I will have to look it up, but I specifically remember the Fontek FR58's getting really strong reviews, as they are what lead me to the 89's. What do you think about these http://www.madisoundspeakerstore.com/approx-3-fullrange/fountek-fr89ex-3-full-range-4-ohm/ They are the 4 ohm version of what I have, so you have heard them before.
