I've gone and done a little bit of a switcharoo. I'll be putting the Focals in my Tour, and I've already got the Partsexpress components installed in my wife's Miata.
I must say for a ~$58 component system, I'm amazed by how good it sounds (and with only a Sony HU pushing them at present).
The Attitude woofers are great with the bass and midrange, and the Ultimate tweets cover the upper frequencies well (possibly a little bright for some people, but perfect in a convertible).
I'm looking forward to getting the amp hooked up on them and cutting the low bass at 60Hz or so. The single 8" sub will take care of the low frequencies.
If anyone is interested, here are the part #s:
299-100 Attitude 6.5" Woofer - 2 @ $15
265-342 Ultimate 1/5" Titanium Tweets - $18
269-668 Ultimate 2-way X-over - @ @ $5
