i got a 99 crown vic , thinking about going with 2 vvx15d2's just wondering how hard are they gonna beat ? i had 2 rockford p3 12 in vented box and was very unhappy with them . plan on building my box of 3/4 or 1 inch mdf . size of box will be around 35 w 20 h 20 d if made of 1 inch it will be 6.1 cubic ft . and how do i go about tuning the box ? ive built sealed boxes before but no vented. and will a hifonics brutus brz1700.1d push them alright ? any info or input welcome.
