What kind of wood did you use?

[ANeonRider 3]

Looks to be 1/2" particle board, and the port doesn't have an opening inside the box that is big enough...

Almost TCAB worthy.

well i got it from home depot i think total was 44 dollars, 3/4 a pain in the a?s to get it home since i dont have a truck, some of my friend do but i didnt wanna ask since they have nice trucks they probably woundnt want their truck scratched, so i used my sis explorer the one on the above pic they berley fit inside the truck, thebox is 42.5"W x 18"H x 26"D the vent is 3"w and 16.5" H the port length is 22.5 hopefully it will sound good.

box is 3.70 cu ft per chamber aftert port and subwoofer displacement total box gross =9.59 cu ft

Did you even read your own thread? You used the wrong wood. That box doesn't have a chance.

Wrong wood is debatable. As long as the cuts were good and it is secured at the joints correctly for a good seal, I highly doubt much difference can be heard between MDF and small particle board. At least it isn't ugly OSB or something.

Someone said the opening for the port internally wasn't big enough. It looks to me that the opening is just as wide inside as the mouth on the outside. Is there a reason to have it wider than the mouth? Serious question.

Umm, no its not. Regrettably son you have just built a box that will be better suited to start a fire than hold subs. You need to go back and buy MDF.

I wasn't bashing you for trying, but you really should have asked a bit deeper when going into something you don't know how to do. It is great that you tried, and almost succeeded but regrettably particle board is no where near a viable solution for a sub box.

I AM A try it out and if it doesnt work good I AM A switch to mdf wood,, the box building process took me like 6 hours i can spend another 6 making another one, but like i said my current box is made out of particle wood and its sounds really good no problems at all for more than a year.
