Yeah...ya did. But that's ok lol. It's not hard to confuse me. I'm still learning the ways of the ICE Guru. *bows*

Anyway...if anyone gets into a conversation with kiki/glass, tell him to bring him & his all knowing self over here!

You can drop down to 5\8"s MDF, save some space. is this a regular cab ranger? are you 4 feet tall? you are going to have a lot of trouble getting a 12" sub back there if its a regular cab. I would do a slot port, you'll get less port noise and it will be easy to build. a 15x1 slot port x 14" long will tune it at 30hz

scratch that, that was for 2.5". at 2 cubes it needs to 18" long. this is for any sub, not taking in to account how the sub will react to the box will will alter tuning freq.

MDF isn't "heavy," it's "dense." :)
you want a very dense grainless material to resist flex. MDF works well for that and it's easy to work with. There are assorted hard woods you could use but they're heavy as well and three times the cost, at least.

Well I ended up building the box out of 1/2" MDF. I'd say it worked just about as well. And yes it is a Std cab ranger. Put me forward a bit from where I usually sit but it isn't too bad. The box itself is only 5" deep. Part of the box extrudes forward in the center (between the seats) to accomidate the double-stack magnet's depth. My dad came up with the genius idea to make it out of a bucket...lol we'll see how well that works; it was just the easy way out, if it doesnt work we're going to build the extrusion out of MDF. I'll post pics of the cardboard mock-up version and the wood version installed today...that is if anyone's interested--anyone?

I'm always interested in seeing install pics :) The box is only 5" deep? How much room does that leave behind the driver's magnet? If it is only an inch or two you will want allow some more room.

I think we left all of 2 1/2 inches behind the mag. Hoping that'll be enough. I'll take pics later, I just woke up like 20 minutes ago. I'm thoroughly enjoying summer *yawns & stretches* :)

PS-when I do post pics, keep in mind that I haven't carpeted the box yet. And I need to go buy some 50w fuses...damn thing blew both my 40 and my 30...*cries*

You used a bucket as part of your box?

Better fiberglass it or else face the flexing issues...

Bleh, it's very temporary. 6 months tops. *scroll up and read about the supra*
