Hey guys, new to the site, in fact i was referred her for this reason. I need to build a speaker box for two JBL 10's that will fit in a 1999 Dodge Ram 1500 ext cab. Under the rear seat so i wont lose the rear seating. I'm experienced enough to go at it alone although I have built speaker boxes before just not without dimensions. So there's my problem. I need print's or some dimensions for a sub box for JBL 10's to fit under my rear seat. Any help would be greatly appreciated cause I have no sub's in this truck and I'm suffering haha.
