Just a quick note on the Kenwood KDC-X702. I've never paid much attention to single din head units as they just never crossed my mind for use in any of the four installs I've done...until I saw and heard this HU last night at the informal gathering a few of us have in the Canadian Tire parking lot every so often. I was rather surprised at not only how good this HU sounded but the features included at the $239.99CDN ($179.99 USD) price. HiRez FLAC playback, two USB ports HD Radio, lots of sound tuning options etc. and while the onboard DSP offers lots of basic tuning control, IMO this might make an excellent HU for a DSP based SQ system for those who don't want or need a DD NAV./DVD HU.
The system I heard it in last night used the HU on board amplifier to drive Focal components up front with a JBL amp driving a Kenwood Excelon 12" subwoofer and while the Focals could have used more power it sounded pretty good.
