[QUOTE="Beatin2door, post: 8356876, member: 664842"] I slid my old enclosure back in my trunk today its 11 cubes empty, anyway if I pull it out towards the cabin of the car 4 more inches I can port the top of the box and still have my sub's and ports firing into the cabin, and I cznstill easily seal it from the trunk. I was gonna try and build a slot port across the top and angle it towards the inside of the cabin with most of the port wall out of the box. I think instead I will try 5 6 inch round ports this will give me 141 square inches of port area, I've been reading and some say round ports need less area. If this is the case I can use smaller or not so many ports. I plan to leave most of the port out of the box and I'm gonna angle them maybe 45 degrees towards the cabin of the car. I been using calculators trying to figure out how long they need to be for 34hz tuning in 9 cubes with subs in box. Can someone help me with this? I get different lengths using different calcs. My other question is am I still gonna need close to 144 sq inches of port if I use the round ports? [/QUOTE]
