ok i think i made up my mind.. Im wanting to go with two 10" Alpine type Rs for my single cab truck.. i currently have two 12" alpine type Es in now and they sound great but just dont get loud enough for me. So do you guys think two 10" type Rs running at around 400 watts a piece would be louder then the two 12" alpine type Es i have right now running at 250 watts a piece? or should i say scratch all the alpine bull and get a single massive 12" sub and make a ported box for it?
