I built my box a while ago and i've finally gotten around mentally to carpet this thing but i am really affraid that i will mess it up. I want it to look seamless but i dont know how i would go about doing that. Its a 3 cu.ft. box and i dont know how many yrds. of carpet i will need and i dont know what i will use for the port itself so its not an "unfinished" look???? i've found that partsexpress.com has awesome prices and they have everything i need so can someone help me out.
