actually u have about 2.9cuft before any displacement

and for a 15 before any displacement to have it in a ported box i dont think thats gonna work might want to step down to a 12 and consider aeros or a sealed box

I already got the sub and amp. would the measurements that I gave before be good for a sealed box. I'm trying to build a box for a reg. cab 03 Dodge Ram1500 and the measurements I gave before are the maximum I could use to build this box?
