Question about building a sub box

[dman4486 5,000+ posts]

Ok screw it I am building one myself.
Ok so I need wood from home depot (I can get them to cut it to the right sizes for me I think)

then box terminals, screws, and what kind of glue do I need?

Can anyone help me find a box plan for a single 12" kicker CVR

wood glue, and yes...hd will cut it for a price and you will have to make the cutout yourself.

I still might be building a box I am getting a quote from someone that lives near me but if it is to much im gonna build it myself

Here is what I want to build

2.25 ft3 (63.7L) + port displacement

3 x 12.5” (7.6x31.8cm) port, 20.5” (52.1cm) long

Power Handling = 300W RMS

Here is my question, What the hell does that mean?

Am I suppose to be able to get the wood sizes I need outta that?

2.25 is your internal displacement, add your port displacement to that number and this gives you an overall displacement. all you have to do is come up with some dimensions that give you the overall displacement.

take your pick. Just make sure the front baffle, where the sub will be, is tall enough for your sub.

Ok I went to home depot and had them cut the wood for me (they did it for free so I figured why not)

I also got titebond II Wood glue and should have some screws in the basement or garage. Anything else I need? Where can I get stuff to carpet it? And should I put it together then cut the hole out or cut the hole out first?

Heh I am a dumbass. I got the box cut to these specs........

Baffle: 23.75x11"

Back: 37.5x11"

Left Side: 12.5x11.75"

Right Side: 11x11"

Bottom and Top: 37.5x12.5"

Port 1: 8x11"

Port 2: 19x11"

2.25ft^3 at 36 htz.

I have a 12 inch sub.........

wow im a jackass

I think I have enough wood left over to make a 12.5 inch front, back and 2 sides. would that still work?

 

[darkhunter139 10+ year member]

Oh wait a min is that ok? The circle does not need to be 12 inches obviously and it should be about 12.5 inches tall if you count the edges of the other pieces of wood (which I can screw the sub into)
