i would like an idea on how a pair of these(http://mbquart.com/2003/en_US/products/prod_detail.asp?isArchive=&cat=auto&series=reference%20series&strt=1&model=RKC+116) up front and a pair of kodas in the back (no tweets) would sound? and do you think that those mb quart speakers i posted the link for are better than these (http://mbquart.com/2003/en_US/products/prod_detail.asp?isArchive=&cat=auto&series=discus%20series&strt=1&model=DSD+216)? i would be running 50 watts to each with a 4x50 watt audiobahn amp.
