Hello everyone, I just got a pair of hcca 15's not to long ago and the time has come to build them a box. Unfortunately I am noob when it comes to sub box designs lol, I am looking for something tuned around 32-35hz my max width is 38in,max depth around 26in and max height around 20in. It will be in a Nissan pathfinder so I'm looking to get about 7.5-8 cubes. For payment just let me know how much ahead of time and I will have paypal ready. Also forgot to mention, subs must be facing up and port towards the rear door.
