I am about to get a system, but i need to get all of it except the enclosure and the install from Best Buy. I am thinking 2 Alpine 12" Type R's and 2 sets of 6.5in Components and then the Alpine Hu for 279.99 and then the Alpine V12 Amp (would that even power everything). Is that set-up good or what do you think would be better, All from best buy though.
