Im thinking of removing the double decker and designung a downfired, ported, false floor in my 4th gen cargo area. Im thinking ported to the rear door. 2 12" subs... single voice coil. Around 300-400 watts of class AB power.

Anybody heard the slim shallow mount subs? The specs sound good but im old school. I want some air to move!

The idea is to downfire the subs and use the trucks floor as the bottom of the enclosure to save on weight and to reduce thickness. I'd want to keep it under 5" high from the floor.

If i went slim sub i could get it to 3" off the floor. Anybody know of any installs like this?

Nice job, SV_Dude! Just gotta ban drinks in the rear seats. :)
BTW, what thickness mdf have you guys found effective enough for subs? For Regular speakers (6.5")?

If you're building a regular sub enclosure then I would use 1/2 or 3/4 mdf. For my application I just lined the steel enclosures with 1/2 mdf. For 6.5 mid bass speakers you normally wouldn't build an enclosure. I used some 1/2 and 1/4 mdf for my mid bass door speakers just to build the spacer rings.
 
Thanks!

Thanks, SV_Dude! I just think that an enclosure would help get cleaner sound and it's additional barrier between cabin and side body panels.

That depends on the mid bass speaker. In my tundra I used 2 layers of sound deadening in the front doors to get rid of any vibrations.

I know that this is kind of off topic but it pertains to the enclosures that you're talking about. When you're choosing your mid bass speakers you need to determine where you're putting them. If you're putting them in a door (the door being the enclosure) then you want to find a mid bass speaker with a high fs rating and a high qts spec. If you're putting a mid bass speaker in your kick panel (kick panel being the enclosure) then you'll want a speaker with a low qts rating. When I said that you don't need an enclosure you kind of need to read in-between the lines. All speakers need enclosures. If not, then you won't have any pressure behind or in front of the speaker and it won't really do much for excursion (cone moving in and out to give the sound wave) and your sound will be horrible. But the location of the speaker usually is the enclosure unless it's a sub woofer and you need a specific volume of sealed or ported space.

Hope this helps! Here are a few good sites to give you some more understanding of how speakers work and it will give you a basic understanding of how to choose each speaker for certain applications.

I'm not sure how much real estate you have under your runner, but I did this on my 2010 Tundra Double Cab.

I'm not too big of a fan of ported boxes, I prefer the quick snappy bass. I was able to fit these boxes in because they were sealed. If you are wanting to try and save some space maybe you can use a sealed enclosure and use a full size sub that has a lot of punch.
