Well Ive decided on the alpine type rs they are in my price range and get loud enough for me, I am going to go with a dual sub setup so what would you guys recommend, do I get 2 12s or 2 15s, I listen to rap/hip-hop and like the lows and want SPL not too much of an sq guy, will my amp even power 15s? I have a Viper D1200.1 (1200wrms@1ohm) so each sub would be getting 600wrms, The 12s are 500wrms and 15s are 750wrms, I think the 15s would be louder but what the hell do i know??
