I have a box that fits under the seat in my truck. it's .74cf and the subs I have are .6cf. will this make a differance? can I do something to cut down on the cubic feet in the box? It's a sealed box.
you mean your subs require .6cuft and the box you already have is .74?
if thats the case just stick the sub in that box. it won't make much of a difference. besides the subs take up space when you put it in the box so your box cuft becomes less.
