need an idea on what speakers to put in, size and all. i can put in 6.5 in factory door panels, i planned to do 4 6.5 on these doors, but thought maybe some 8s would be needed to keep up with this set up.
So far my set up is in a 2004 chevy tahoe z71
crescendo BC 5800 @.5 ohm
four Fi Bl 18 with cooling option in a 38 ft^3 box @ 35 hertz
