yeah thats what i figured aaron because the momo website accually gave some specs to a ported box on their site. So mel u think i should jus keep the box i got now and throw 2 type R's and a bigger amp in? The type r's are on back back order and i didnt really wanna go wit a bigger amp but i mean i guess if its gonna b better than 2 ported momos on 600 watts i might do it
