sub box materials

hey, im looking into building a buddy of mine a sub box, i was wondering where the best place to buy the box inserts for the power in and audio in, its gonna have 2 10" and an amp, want to make it look clean, plan on doing all the wiring for the amp and subs inside the box so i just need to run the power and audio plugs from the stereo to the box

Visions or off the internet what ar eyou making the box out of

make the box ONLY out of 5/8 MDF. Don't use anything else, or it is ot going ot be dense enough, and it will probably sound like ass
