Also, from what I understand the stock amp does not have non-fading bass, when you fade forwards you lose 6x9s. So if you upgrade the fronts and the R deck with less-efficient speakers, you need to disconnect the R ddoors or they overpower everything else.

Kapps, in my experience, are pretty inefficient too. Used to be an Infinity dealer, would not recommend any Kappa driver off of deck power. That 6x9 might be nice, but IMO it needs an amp.

I would politely suggest my avincar brand 6x9 woofers as being efficient enough for that. $90 a pair, if you're interested. I'll post some pics when I get time - nothing breathtaking, metal frame, poly cone with silver fairy dust on it that's supposed to be titanium (and I'm sure there are trace elements in there that CSI could find..., butyl-rubber type surround, vented pole piece on the back for cooling, bumped back plate for more throw.

I've got some people interested in them and I'll post pics soon, and get back to the PM's now that they are in stock.
