Well i am going to attempt to build a sub box for under my rear seat of my 03 screw. Right now i am not sure what sub will go into it either a kicker compvr 12 a rockford punch 3 12 inch sub or an alpine type r (i think) 12. What ever sub it will have it will be powered by a 800 watt amp at peak so i am considering building the box out of 3/4 mdf. Will 3/4 be enough or should i go to 1 inch?

 

3/4 will be enough, watch out for 05 alpine type r's, they are fairly deep subs. But they are propablly the best sub on your list.
