I am planning on building an amp box to put in the back of my jeep to hold a jbl 80/4 and 600/1. It will be a box with hinges and a top so it looks just like a carpeted box from the outside but when you open it up the subs are there. I have a few questions though. How much room does there need to be around the amp for it to ventilate and should I cut holes in the side to let it cool easier. Secondly, should I use MDF or does it not matter what kind of would I use? Also, do you guys think it would be better to just mount one of my amps on the box and the other under a seat or should i try this amp box idea.
