Hi guys, i have two Cvr12, i will construct a ported box for them. I have two question, the first is what can of wood i have to use to construct a good box? the second is that kicker recommends rectangular ports, i will go with them but i cant do it at sides of the box because they will be obstructed with the trunk, so i will do each port ( 2 port) at the fron of the box, what will change that? i always see that the ports that are in the sides always the sub its at the same side of the port, why is that? how will be eith the port in the front? will be the same dimensions of the port? thx guys.
