    Sony xm1s 290rms and JL W3v3 12inch sealed, Passat 2012 cheep sub setup

    Hi, This would be my 1st sub and amp in car Is there anything wrong with my setup or i am asking for too much bass on low budget 290rms? Does trunk in sedan block a lot of bass ? Do i need to move my sub position ? is .75 inch layer of fibreglas on all sides of enclosure and .25 inch on top...
