yah, those are three 10's. i had a friend make the box to fit exact so i didnt loose any leg room, and it worked. i forget the dimensions. i will get them for you though. i am selling those to a guy though, and have another set up. i will get that done in month prolly.
i know that if i had a bigger box, which could happen if i had a cut out, and i would love to have an extended cab, but since i dont have those i just have what u see. i dont think the air space is correct for it. it could be louder w/ a larger box. the subs are thunder4000's. just 400 max w/ each speaker. the amp is on the other side, the box doesnt go all they way across. talk to me on sonoma2002 if ya want.
i sold those subs tonight. i am savin up for a 5" t.v. screen and hook a dvd and playstation up to it. i am gonna put in my gove box door. there is a dude on here w/ that done. i like it. thats what i plan on doin next though. and then some more subs, and a BA setup.
