Need your opinions and suggestions

Ok I looked around and have seen  Alpine and Rockford seem to have the most possitves among the people in here. I went to the Alpine web site and this is what they set up for my car, a Alpine CDA-7893 in-dash CD player, 4 Alpine SWR-1221D type R subwoofers, 2 Alpine MRD-M500 V12 accuclas S-D mono amplifier, a Alpine MRV-T420 2/1 channel power amplifier, 2 Alpine SPR-136A 5 1/4 Speakers and 2 Alpine SPR-694A 6X9 speakers. Now I know this is some big bucks but I can get it for $2100 compaired to $3700 that they quoted. Now is it worth the money or am I going to pay for the name?
