I've replaced the whole shootin' match with:

Alpine CDA-9820XM - fm, xm-sat, cd, 2 pre outs, sub out
Alpine KCA-420i - iPod interface
Boston Acoustics RX47 4.5" spkrs in front doors
Boston Acoustics NX57 5.25" spkrs in rear doors

Coolest coupla things so far (1st 24 hours of ownership, not nearly enough driving!):

(1) XM satellite radio - Out in the boonies, 200+ channels of non drifting/fading/garbled content choices - music without commercial interruption - is fan-freakin'-tastic.

(2)The Alpine Bass Engine, which I thought would be some horse's ass bass boost, instead turns out to allow you to choose a center freq, width of range affected and level of boost. So, in my case, with smallish speaks dropping away somwhere between 60-80, centering on 60hz with a moderate breadth and 3dB of boost improved the tonal balance dramatically.

(3) In theory, since no one in the family owns one yet, the iPod link allows the iPod to be treated like a server controlled from the head unit, with all menu information displayed and selected from among there, while the iPod rests, probably velcro'd in a well in the dash.

I guess this qualifies as a guilty pleasure for an all tube mostly analog two channel home audio guy . . . . ;-0
