trying to build a custom box for 2 sa8's on 800 watts rms. The max size of a box I can get in the space I have is 3.2 cubic feet (not taking into account port and sub displacement) and for 2 sa8's sundown recommends .5 to .75 cubic feet. So for 2 I would need only 1.5 cubic feet. How does building the box bigger than recommended size effect performance? The box is going in a 2011 crew cab Silverado, ported, out fire. Also with this being said only having a height of 11.5 inches to work with could an sa10 work or would it be too close to the edges? Also considering the box angles downwards toward the back woukd mourning depth be an issue with the 10's?
Also how would selaed 10's in the right box compare to ported 8's? It looks like selaed isn't recomended on the sa8 or 10? Thanks
