hi, i just got a 12 inch pioneer sub for 30 bucks from my friend. it says 800 max, 150 nom or something like that. i want to build a box in woodshop and i was wondering what kind i should make. ported? what dimensions? all information would be appreciated. and also what type of amp should i get? i have stock speakers right now but eventually i want to get all aftermarket ones, so keep that in mind. thanks
