Everything others are saying, but if possible even make a rack for a regular HD in it (if theres room inside.. if components arent too big ya know..). then people can just buy the thing itself, put their own HD in it, and save a ton of $.. I think thats empegs problem, fixed space. Also a USB connection for external HD like they said (hey, every car should have 40+gigs of music space). And ya must support CDR/CDRW.. DVD wouldnt be much plus i think, but could be.. The 3 sets of outs would be a major plus. front rear and sub would help alot.. Also how about a universal infrared sensor (instead of only being restricted to the companies remote, how about let everyone use companies or their own and program its buttons? save alot of headache if someone could go buy a $10 remote instead of waiting months on a factory list only to pay $50 for a remote control..
My 24 cents.
