[Bigrick31 10+ year member]

well i going to go do some more work on it. gotta figure out the air space so i can calculate my ports/s

 

[Bigrick31 10+ year member]

so my box is 4.824^3ft frigin huge!!!!!! well the sub displaces .9 cu ft so im down to 3.924 and then port area as well. just gotta calculate my ports now.

might be late. but Kitty Hair would have been better to fill the gaps then using the fleece

yea im going to lay that over the top of the fleece. some of the gaps were kinda big thats why i went with fleece first and i didnt feel like messing with fiberglass at that moment either. lol.

so if anyone is board and wants to give me port dimensions useing either 3 or 4" pvc to tune my box to 35hz that would be kick @ss!

Lol, keep it up, you'll ahve a ton of sanding ahead of you it you wanna make it look real nice.

Two 4" PVC ports with each of them being 12.5" long will give you a 35hz tuning frequency and a net volume of about 3.6 cubic feet. Three 4" ports each being 21" long will give you a 35hz tuning and a 3.4 net box volume.

Is this for a single 10"? If so, it's going to be way too big.

Looks like a 12. IMO, too big for a box under the rear seat. But looks like he's making it possible.

 

[Bigrick31 10+ year member]

one single 12 and and im going with 2 3" ports with a flare 5.52" long that should give me 35hz at the 4.634^3ft of space i have my sub only displace .19 not .9 like i mis read

so heres what we got today

this is where i planned for the stock bolts of the truck the ones that usually hold dont the seat to come in through the speaker box. as you can see i took a piece of wood for the bolts to go through and then using wooden dowels i hot glued the piece to my box to figure out the depth of the wooden bracket.

here i covered the bracket with fiberglass

laying out my ports. got some nifty stuff from the hardware store to make my ports out of

 

[Bigrick31 10+ year member]

so i went to the plumbing section of the hardware store to find some pipe to use for my ports. i cant remember what the stuff is called its black tubing not pvc well anyways as i was heading out i noticed the plugs used to mount in floors so the description said and i really liked the shinny blue ring on them so i decided i would use them as the flare end for my ports making them much easier to attach to my box.

here i cut the tubing and inserted into the plugs the measure 5.52" long and have a 3" inner diameter.

and here i sealed everything up with liquid nails for one to hold everything together and two to stop any air leaks.
