1 hd315" in a GMC Envoy, how should I have the box design, sup up and port back? sub back and port back. I was thinking of doing sub up and port back so he has the other half of the trunk to use.
lol i got the same exact setup cept mine is in a trailblazer ( which is pretty mucvh the same vehicle with a different grill ) lol i did sub up port back it sounds amazing, i can get u the plans if ya want, dave drew them up for me. its 4 cubes to 35hz and with 4 cubes it pretty much takes up the whole back lol
