can someone give me all the dimensions and stuff on how to build a single 12 for the back seat of my 2004 f150 4 door?
thanks

get a tape measure and be creative more air space the better

Don't trust anyone else's dimensions. You have the truck in your driveway and thats the best way to get your dimensions. Just keep a few things in mind that a lot of people over look.
You need 1.5" of clearance between the baffle and floor. If the sub is against the floor the surround will get damaged and sound doesn't get out. You were looking at a 12" box on ebay that has rubber feet that are only 1" long. Those feet will sink about a 1/4"-1/2" into the carpet and your sub will end up smashed against the floor. Not good.
You can also make your box come out about 3-4 inches in front of the seat for extra air space. It may look a little funny but it won't affect the foot space since nobody rides with there feet tucked up against there seat anyways. Since your using 12's your going to need all the air space you can get.
Good luck.

he is very correct about that is there a reason your going with 12s in a truck 10s will be much better imo

The only reason i was going with a 12's is cause i already have one and it is in a box under the rear seat but the box was built by the guy that had it before me and has a couple wholes in the bottom because he tried to build it out of fiberglass so i would like to build one out of mdf that is sealed and mabye a little bit bigger.

I wasn't going to argue the fact that 10's will smoke 12's in the limited space available but if your open to suggestions then go with 10's.
10's in there optimum air space will sound better than 12's in there minimum or in this case....bellow minimum air space.

With one 12 you might have the minimum air space but you need to calculate for internal air space. Check your mounting depth on that 12 also. There arent many 12's that will fit under your seats. keep in mind that you can buy a pair of new JL Auido 10wo v2's for $100 each and they are a very impressive sub for the price.

ok well what are the best subs that are shallow for a good price that will work good?

joefox

Try to stay away from "shallow mount" subs. If shallow Mount subs were just as good as regular full depth subs they would all be shallow mount.
What you need to do is.....
1.Measure your truck.
2.Draw out your design that you intend on making.
3.Draw a side profile so you can figure out your maximum mounting depth.
4.Find the best sub thats within your budget and will also fit the box.
My enclosures have a molded top cap that allows the magnet to stick out the top of the box and the mounting depth is 6.125"

If you click on the picture it will show the rest of the pictures and there is a drawing that shows how the magnet cap on top works.
You can make a regular box that has a mounting depth around 4.75"-5" if built right.
Good luck.
