I have friend with a regular cab Ford Ranger and he wants to build fiberglass boxes to go behind the seat. It is a 93, and he only has a little bit of room to work with. I told him that shallow mounts would fit easily, but he says that he wants to go with a pair of 8s, because he is big into SQ, and really doesn't care for the heavy bass (puss can't stand listening to my Mojo). Anyway, he asked for my advice, but I have never run 8s, or a true mid bass sub. I am seeing a lot of REs avaiable, as well as JL, RF, and MB Quarts. Anybody running 8s now that can help me out? Aslo, I was really surprised by the crazy low sensitivity ratings on these speakers. Most that I have looked at are in the low 80s, even the JLs. Thanks for any help.
