Okay...so let me get in some back ground story:
I have a 1997 Z71 extended cab chevy truck. I have the rear seat removed. I am planning on putting 4 JL 12W3v2's into the back. But for now i only have 2, the other 2 will wait till after the baby (real child) has arrived. SO, in the mean time, i will just be putting in 2.
So on to some of the cab dimensions and what i have to work with.
The cab from one side to the other is 63". From back of the cab to where i want to stop the box is about 32". My height from the floor to the bottom of the window is 30 inches.
On to my box idea. My plan is to build 4 individual chambers. I have plenty of room to do 2 ported, but prefer 4 sealed. So that argument is dead and over with. A few models of my basic box idea"
A few things on the images, the area shown is internal dimensions, the gaps between the textures represents a 3/4 MDF wall. I didn't want to go too deep just to make it look pretty, just give a general idea.
The internal dimensions are the same for each, 14.5h X 16.5w x 9.5d Gives me 1.32 cubes. My driver displacement is .07 which brings me to 1.25'^3, which is what JL recommends.
Now on to the part which will be somewhat hard to explain. Basically the 4 boxes will be built in rings. As in 5 walls (leaving the hole side open) will be built and glued together, then 4 walls glued/secured to the side of the first box, and then so on and so forth until 4 chambers are together.
Then the plan is to "float" the chambers in the cab. This will give me a chance to still have my jack kit, wiring, whatever else i need hidden between the rear of the box and the rear of the cab. And when i mean float, i mean float. Because the box will not actually set on the floor board. It will be generously supported and bracketed, but free space will the had under the box.
Now you ask, what am i planning on doing to the front face of the chambers that was left open? Well, i am going to cut a full sheet of MDF to cover all 4 open chambers, and then the holes for the subs and blah blah blah.
Now the box will eventually come up just under the bottome of the window. I am going to build a box type enclosure out of MDF and plexiglass to house my amps. I won't worry too much about lack of airflow and overheating my amps because i will have installed some very quiet yet powerful computer fans in calculated positions to keep the amps nice and cool.
Also, since i am only installing 2 subs and leaving the 2 chambers unused, i will only cut out the 2 sub ports that i need, and leaving the other 2 sealed for when i have the other speakers.
So through the poor explanations and jibberish, anybody have comments or suggestions?
