OK the SEL comes standard with a 6 disc In-Dash Changer w/MP3 and 6 spkrs. For $420 more you can get the Audiophile 6-Disc In-Dash Changer w/MP3 Player and 8-Spkrs . As near as I can tell you are effectively playing $420 to only gain 2 more speakers. Could that be correct? Maybe they up the wattage too but that seems like a lot of $$$ for a minor stereo upgrade.
